Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge talk (Post)}
Some new test. Now I cannot connect from Automation server to my gateway in any way also from my office setup with my unit directly connected to my router by dhcp. I can use the IDE and the tool "Connect Edge Gateway" and successfully connect to my server/link to my Automation server account. However no PLC will respond from Automation server "Network scan". I guess the traffic should be initiated by the gateway towards automation server? Any tips on how I can diagnose my problem? Ports to be opened etc? Thing is that this has been working previously but not now (base system has been updated from debian 12 to debian 13, but I dont know at which point it has stopped working). Setup as before. A "Codesys Control for Linux SL" running on a debian 13 installation. Any help/tips appreciated! Per Update. Found the error. Had a wrong gateway-setting. Which meant the PLC could not reach internet. Checked by "ping google.com" from the PLC.

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Hello Mr. Seidel, both the master and the slave axis are modulo. Basically the situation is as follows: One master cycle is 100 units. Slave's modulo length is 2000 units. In the CAM table I defined 10 master cycles on X axis - 1000 units and on the Y axis is the slave - 2000 units. Then depending on the master position 0 to 1000 units the slave's position is plotted on the Y axis - 0 to 2000 units. For example, while the master is executing the 3rd cycle i.e. above 200 units, I trigger the STO function of the slave and it stops. The master executed his cycle but the slave was stopped during the execution. How can I set the slave to continue the CAM sequence from the point where it stopped i.e. third cycle of the master? When I reset the slave error and sync again, everyrhing starts from master's 0 position. Best Regards Konstantin Kolev

Post by ryandmg on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
Hey Everyone, I'm having a bit of a struggle finding settings that will reliably maintain a connection between the webvisu and a touchscreen client. Every so often the HMI disconnects and will perpetually display the red spinning arrow with the "Error Happened, Will resume automatically" text. Power cycling the HMI to force a reconnect will re-establish comms. It seems to happen during periods of inactivity if that's a clue. From what I've gathered so far this seems to have something to do with the webvisu update rate, buffer size as well as the visu task scan rate. We first tried the default settings as follows: Webvisu Update Rate: 200 ms Webvisu Buffer Size: 50,000 Visu Task Scan Rate: 100 ms Priority 31 Other Tasks for Reference: Main Task Scan Rate: 100 ms Priority 1 Alarm Manager Scan Rate: 50 ms Priority 31 Ethercat Task: 4 ms Priority 1 This would disconnect some what regularly. We then made the following changes to try and stabilize: Webvisu Update Rate: 150 ms Webvisu Buffer Size: 75,000 Visu Task Scan Rate: 75 ms Kept other tasks the same. This seems to disconnect even more frequently. Also for reference the network is very small and only consists of the PLC, a small switch and the HMI. We're also not controlling frames from outside the visu program itself. The frame changes are all done natively. Any suggestions to get this to stop disconnecting? Oh and whatever the issue is the log does not record it. Figured I would ask here before opening a ticket. Thanks in advance for your help!

Hello, I am using codesys Modbus TCP client (4.4.0.0) to communicate with a python modbus server (package pyModbusTCP). I first start my python server on the distant machine. After a fresh codesys compilation, a plc connection/transfer and a PLC run, the modbus connection is OK. Every time in this context the connection is created correctly. When I shut down the server, the modbus connection falls, that is normal. When I restart the python server, impossible to recreate the modbus connexion. With the client autoreconnection, I see on my server that the client tries to connect but unsuccesfully. I have the following message : DEBUG:pyModbusTCP.server:accept new connection from ClientInfo(address='192.168.1.20', port=33476) DEBUG:pyModbusTCP.server:Exception during request handling: NetworkError('recv return null') I tried to stop the codesys client and to restart it with these commands : Modbus_TCP_Client.xStop := True; // Or False Modbus_TCP_Client.Enable := True; // Or False Modbus_TCP_Server.Enable := True; // Or False I tried to confirm the error manually to force reconnection with: Modbus_TCP_Server_Motors.xConfirmError := TRUE; I tried also this command to STOP/RESET/START client and server (codesys side) but nothing happens : status_client := Modbus_TCP_Client.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.STOP); // .RESET & .START The answer of this function when executed is "status_client = NOT_SUPPORTED" It seems that is a socket problem, but I do not understand if it is on the client or server side. I tried a modbus simulator called "ananas.exe" and the result is the same. Impossible to get a modbus reconnection. What is different at the first connection and at a reconnection attempt ?

Post by jeindhoven on Deploying to raspberry pi 5 hangs ^{CODESYS Forge talk (Post)}
Yep sure, though now that i think of it, its a pi 4. My bad. The whole ordeal was necessary to use the VGA666 adapter. That needs the old graphical system and GPIO directly on the CPU. Edit: Putty on the virtual development machine connects fine. But i did change the login/pw. The account is still a sudo'er so that should be all right. Edit2: Sorry i get a "Comment rate limit exceeded" from the forum. Then i'll add it as edit here. So i have tried the stock raspberry pi image on a different pi5 (truly 5 this time). Packages updated. Standard password. Same symptoms, no runtime deployed and long hang time. Versions of this pi: pi@raspberrypi:~ $ uname -a Linux raspberrypi 6.12.25+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.25-1+rpt1 (2025-04-30) aarch64 GNU/Linux pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm pi@raspberrypi:~ $ apt list --installed | grep openssh-server openssh-server/stable,now 1:9.2p1-2+deb12u6 arm64 [installed,automatic] Attached is the Device information and error text that Codesys comes up with. Edit 3 (Comment rate limit, otherwise it would be a new post) Now i have tried booting an older native Windows 10 machine (no virtualization), and it just works as expected. I have now a raspberry pi 4 and raspberry pi 5 with version 4.16.0.0 of the control application. Windows 10 native: build 19045 (same as virtualised Win 10), same .NET version, same CODESYS version. It seems that running CODESYS virtualized somehow messes with the deployment?

Post by serwis on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Post by tk096 on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

(What ever reason I’ve been told this is “normal”). If I use Device License Read It will successfully read all the licenses correctly. Now the issue is every 2 hours and between 4. For what ever reason the communications seems to end and lock up for about 20 seconds. During this time even if I was logged into the PLC it would kick me off and I’d have to re type the password to enter. Most of the devices can handle this however the RTU flags up a communications failure at the SCADA and is raising alarms every 2 hours and 4 mins. We’ve had multiple people go through the code to check for anything obvious. Does anyone have any ideas?

Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled. See following issue: CDS-81506 - CODESYS Control SysFile system file access vulnerability. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2.

Post by mgabryel on Problems with CAN 2.0 comunication on Wago PLC (Codesys 3.5) ^{CODESYS Forge talk (Post)}
Hello, I am trying to program CAN Bus comunication on WAGO PLC (more precisely on WAGO Touch Monitor model TP600). I am using for this purpose library "WagoAppCanLayer2" from Wago company. My IDE for programming this device is CODESYS V3.5 SP19 Patch 2 + (64-bit). My program is written in Structured text using function blocks from previously mentioned library. Here is code of this program: 1) Variables declarations: PROGRAM PLC_PRG VAR oOpenInterface : WagoAppCanLayer2.FbCanL2Open :=( udiBaudrate := 125000 ); xInterfaceIsOpen : BOOL; sInterfaceInfo : STRING; oReceive : WagoAppCanLayer2.FbCanRx29BitFrame :=( xBufferMode := FALSE, wCanId := 16#181 ); xRecv : BOOL; sReceiveInfo : STRING; oSend : WagoAppCanLayer2.FbCanTx29BitFrame :=( dwCanId := 16#100, //was 16#201 xRtrFrame := FALSE ); xSend : BOOL; sSendInfo : STRING; oCanDiag : WagoAppCanLayer2.FbCanErrorInfo; xRst : BOOL; aSendData : ARRAY [1..8] OF BYTE; bSendLen : BYTE; TON_0 : TON; TON_1 : TON; END_VAR 2) Program body: oOpenInterface( xEnable := NOT xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE ); sInterfaceInfo := oOpenInterface.oStatus.GetDescription(); xInterfaceIsOpen S= oOpenInterface.xValid AND NOT oOpenInterface.xError; oReceive( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xRxTrigger := xRecv ); sReceiveInfo := oReceive.oStatus.GetDescription(); IF NOT xRecv THEN IF oReceive.bRxNBytes > 0 THEN oReceive.aRxBuffer[1]; oReceive.aRxBuffer[2]; oReceive.aRxBuffer[3]; oReceive.aRxBuffer[4]; oReceive.aRxBuffer[5]; oReceive.aRxBuffer[6]; oReceive.aRxBuffer[7]; oReceive.aRxBuffer[8]; END_IF xRecv := TRUE; END_IF aSendData[1] := 224; aSendData[2] := 13; aSendData[3] := 14; aSendData[4] := 15; aSendData[5] := 222; aSendData[6] := 13; aSendData[7] := 14; aSendData[8] := 15; bSendLen := 8; TON_0(IN:= NOT TON_1.Q, PT:= T#2S , Q=>xSend, ET=> ); TON_1(IN:= TON_0.Q, PT:= T#2S , Q=>, ET=> ); oSend( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, aTxBuffer := aSendData, bTxNBytes := bSendLen, xTxTrigger := xSend ); sSendInfo := oSend.oStatus.GetDescription(); oCanDiag( xEnable := TRUE, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xTriggerResetCounter := xRst, xValid=> , xError=> , oStatus=> , wBusState=> , wBusDiag=> , uiRxOverflowsL2=> , uiTxOverflowsL2=> , uiRxOverflows=> , uiMsgTimeouts=> , uiBusOffs=> , uiBusWarnings=> ); Program first opens comunication on CAN 2 device and then periodically try send one CAN data frame. After starting program CAN 2 interface is properly open. The xSend variable is toggling with period 2s. When program sends data an "Tx overflow" error appears. When I am watching CAN_H line on DSub 9 socket i am not able to see proper CAN frames - see screenshot attached to this message. Could somebody help me determine what is wrong with this program. Best regards

Post by gustavocsw on MQTT memory leak problem ^{CODESYS Forge talk (Post)}
Hello everyone, I'm using the IoT Library to implement the MQTT communication with my local broker server in order to publish and subscribe at specifics topics to share and consume information about my application. But, it seems that are occurring some memory leak problem in a "high" frequency (more than 10 Hz) subscribe process. I follow the same method as in IoT Lib exemples, and at first looks perfect but my PLC was rebooting frequently and when I check its memory usage that was increasing as fast as the subscribe massage was sent. I'm using a WEG PLC410 and a WEG PLC500, and this error occurred in both of them (including in CODESYS Control Win x64). The application sends to the system a message JSON with the float payload Ex. {"data" : 0.8500}, but this happens with a INT, or BOL as well. I use the follow code in my application to find the value: //FindFirstValueByKey VARs PROGRAM JSON_VELO VAR //------Setting the JSON Subscriber to Set the Relay Value jsonDataVelo : JSON.JSONData; jsonByteArrayReaderVelo : JSON.JSONByteArrayReader; xST1okVelo : BOOL; FindFirstValueByKeyVelo : JSON.FindFirstValueByKey; jsonElementVelo : JSON.JSONElement; xDoneReaderVelo : BOOL; xDoneFindVelo : BOOL; //STRING and WSTRING for Subscribe the massage sPayloadJsonVelo : STRING := 'opa'; psPayloadJsonVelo : POINTER TO BYTE := ADR(sPayloadJsonVelo); //wsPayloadJsonRelaySet : WSTRING := "opa"; wsPayloadJsonVelo : WSTRING := STRING_TO_WSTRING('opa'); pwsPayloadJsonVelo : POINTER TO WORD := ADR(wsPayloadJsonVelo); lrVelo : LREAL; xKeepAliveVelo : BOOL; xSetVelo : BOOL; RSSet : RS; LIMPAR : STRING; //Find the msg end sFindVelo : STRING := '}'; psFindVelo : POINTER TO STRING := ADR(sFindVelo); iLenVelo : INT; iSizeVelo : INT := 12; udiContMsg : UDINT; END_VAR // FindFirstValueByKey CODE // Relay Set configuration xSetVelo := MQTT_SUBSCRIBER.RSVelo.Q1; IF xSetVelo THEN xKeepAliveVelo := TRUE; END_IF IF xKeepAliveVelo THEN udiContMsg := udiContMsg + 1; iLenVelo := TO_INT(StrLenA(psPayloadJsonVelo)); iSizeVelo := iLenVelo - TO_INT(MQTT_SUBSCRIBER.udiPayloadSizeVelo); StrDeleteA(psPayloadJsonVelo,iSizeVelo,iLenVelo); wsPayloadJsonVelo := STRING_TO_WSTRING(sPayloadJsonVelo); pwsPayloadJsonVelo := ADR(wsPayloadJsonVelo); //MQTT.ConvertUTF8toUTF16(sourceStart:= ADR(sPayloadJsonVelo), targetStart:= ADR(wsPayloadJsonVelo), dwTargetBufferSize:= TAM, bStrictConversion:= 1); //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := TRUE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := xDoneReaderVelo, wsKey := "data", diStartIndex:= 0, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); IF xDoneFindVelo THEN lrVelo := jsonElementVelo.value.lrValue; //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := FALSE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := FALSE, wsKey := "data", diStartIndex:= 1, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); xKeepAliveVelo := FALSE; GVL.xSetVeloRead := TRUE; END_IF END_IF And this to subscribe at the topic: //SUBSCRIBE VAR: //----------------- Subscribe Velocity ----------------------- MQTTSubscribeVelo : MQTT.MQTTSubscribe;//Variable MQTTSubscriber block -X - function-X wsTopicSubscribeVelo : WSTRING(1024) := "CORE/odometry/GET/data/simp"; // Topic to publish a message sSubscribeMassageVelo : STRING; udiPayloadSizeVelo : UDINT; xSDoneVelo : BOOL; xSErrorVelo : BOOL; xReceiveVelo : BOOL; eSTypeVelo : MQTT.MQTT_ERROR; eSMQTTErrorVelo : MQTT.MQTT_ERROR; RSVelo : RS; udiCont : UDINT; //SUBSCRIBE CODE: MQTTSubscribeVelo( xEnable:= MQTT_CLIENT.xConnection_Broker AND NOT xSErrorVelo AND NOT JSON_VELO.xKeepAliveVelo, pbPayload:= JSON_VELO.psPayloadJsonVelo, udiMaxPayloadSize:= SIZEOF(JSON_VELO.sPayloadJsonVelo), udiPayloadSize => udiPayloadSizeVelo, mqttClient:= MQTT_CLIENT.ClientMQTT, wsTopicFilter:=wsTopicSubscribeVelo, xDone => xSDoneVelo, xError=> xSErrorVelo, xReceived => xReceiveVelo, eMQTTError=> eSMQTTErrorVelo ); RSVelo(SET := xReceiveVelo, RESET1 := JSON_VELO.xKeepAliveVelo);

Post by george32 on Readable IO names ^{CODESYS Forge talk (Post)}
Hello Folks, I have a quite basic understanding of how PLC programming works. However I keep getting stuck on 1 problem I could not get my head around. The problem is as follow: I have a PLC with 60 IO (20 inputs, 40 outputs). Each IO is defined as a function block. Furthermore I have an external IO card connected trough a CanBus connection. This IO card has 4 analog input channels (USINT), 4 digital inputs (Bool) and 4, digital outputs (Bool) Because I have 2 different components which both has data have I made 4 arrays to store the data off every component in one variable. PLC_Input: Array [1..20] of BOOL; PLC_Output: Array [1..40] of BOOL IOCard_Input: Array [1..8] of BOOL IOCard_Output: Array [1..4] of BOOL Because the control and reading of the different in and outputs is done by a TCP connection I want to use some kind of enumeration or struct to give each index a name so that my main would be a little bit more readable instead of all the magic numbers. Also this would make my program more dynamic for the furter in case I need to changes some in the IO nummers. For example: pump is placed on the fysical terminal strip number place 54, which is the 3th output of the IO card in the program: if I am sending a message with value 54 I would like to control IOCard_Output[3]. If there is a solution or methode to get this done, I can eventually do the following in my main program: IOCard_Output[Pump]. I have tried the following: IOCard_Output[Pump - 51] with an enumration but this keeps raising an error I hope some of you could help me further with this problem. In gross lines: I want to couple all the different IO to a more readable name and this readable name should control the right Array index Thanks in advance, George

Post by gmau on Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired ^{CODESYS Forge talk (Post)}
Hello, I am writing to You with the problem of Profinet communication in my Codesys V2.5 SP21 project working on Codesys Control RTE V3 x64 device. I have implemented multiple Profinet devices in the network, the Profinet itself is configured properly, based on the hardware and software parameters of the industrial PC (Windows 10 IoT). My Profinet network contains such Profinet devices as a robot, IO-Link master with some devices on it, IO modules, safety, vision sensor (the configuration is attached to this topic). Once every few hours, sometimes more often, sometimes not even once a day, the error show up at one, two or a few random modules at the same time, every one is the same: "Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired". The communication is then lost with that module, but it is up instantly. It is not such a problem when it comes to regular IOs, but with safety or rotation table, it causes errors and machine stops. I have tried multiple solution based on any forum suggestions, manuals, etc., but it is still happening. Mabye when I turned on the Watchdog for this communication, it is happening less times, but still, I could not turning up the Watchdog parameters at the expense of cycle time of the process. The same is with Send Clock, Reduction and DHT. I have one of the ethernet port on the PC configured with CmpEt1000Drv driver. The card itself is Intel Ethernet Connection I219-LM. These devices are connected to one EKI-2728-NI-A Profinet switch (it was changed from the standard non Profinet one, but still nothing has changed). As I said ealier, I am attaching all the configurations for each device and the communication itself - if any of You had the same problems or have any ideas what could be the cause, I would be much gratefull for any help. For now I am out of ideas, if You have any additional question, please ask. Sincerely, PF

Post by kurtk on SysProcess Execute Command unable to run commands with special characters ^{CODESYS Forge talk (Post)}
Thank you for this additional information. Could you please provide the references to the official documentation where you found this information ? I got as far as: Then insert this: [SysProcess] BasePriority=Realtime Command=AllowAll devoid of references of where the CodesysContol.cfg file was located or of the need to run codesys as root I incrementally located bits of information with perplexity searches but remained mired at error 25 ERR_NO_ACCESS I am curious whether root access is MANDATORY to run SysProcessExecuteCommand (- and/or any other SysProcess functions) or if a more access-constrained User=quasiroot could suffice without the security concerns ? Apparently codesys runs fine without User=root for almost everything... That raises the question: What IS the default codesys user ? I notice in the prototypes: VAR sCommand : STRING := '/usr/bin/whoami'; sOutput : STRING(255); refCommand : REFERENCE TO STRING; refOutput : REFERENCE TO STRING; resultCmd : UDINT; END_VAR whenever I attempt to build this Codesys v3.5 SP2 whines that "cannot convert type REFERENCE TO STRING to STRING" don't remember the exact message... Apparently this happens whenever a fixed-length string is involved. if I get rid of (255) and just set the string := ' '; that is sufficient to make the compiler happy. Is this a recently enforced constraint ? Why does this compile for you and not for me ? There are references to functions / utilities which are used/needed to massage the string references - but I see no specific details... I also notice you specify: Make sure the lib SysProcessImplementation, SysTypes, and CmpErrors is on the project. I don't comprehend why all of the dependent libraries are not automatically referenced, added ? I don't recall seeing anywhere but here that SysProcessImplementation must be included... It just seems odd that the default is to exclude essential libraries, or require alchemical conjuring to assemble all the ingredients for gnat soup ;-) Thanks a lot... I'm still a codesys newby getting my wheels on - or sometimes just partially on

Post by spiessli on Raspberry Pi 4 with Legacy Drivers and Codesys 3.5.19 Patch 4 ^{CODESYS Forge talk (Post)}
Hi, I wanted to use the Adafruit Hat for the Raspberry and get acquainted with Softmotion using servos for RC models. This did work great with Codesys 3.5.19 Patch 1, but with Patch 4 and 5 i get errors. I suspect changes in the SoftMotion library have broken dependencies in the legacy drivers, might that be true? Thanks for any hint, spiessli Here the error log: ------ Übersetzungslauf gestartet: Applikation: Device.Application ------- Code typisieren... Code erzeugen...

Post by ara32 on CODESYS 4 Linux: ^{CODESYS Forge talk (Post)}
Hello! I managed to correctly launch CODESYS Developer Studio 3.5.17, almost all functionality works. The only issue remaining is that when connecting to a device and obtaining its public key, the NCryptEncrypt function is called, which is not fully implemented in the DLL source code, resulting in the connection not being established. Currently, the code of this function in the Wine repository looks like this: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG || flags & NCRYPT_PAD_OAEP_FLAG) { FIXME("No padding and oaep padding not supported\n"); return NTE_NOT_SUPPORTED; } if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } The program crashes due to the NCRYPT_PAD_OAEP_FLAG flag. I'm not proficient in C++, but I attempted to add handling myself, and here's the result: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG) { FIXME("No padding not supported\n"); return NTE_NOT_SUPPORTED; } BCRYPT_OAEP_PADDING_INFO oaepInfo = { 0 }; oaepInfo.pszAlgId = BCRYPT_SHA1_ALGORITHM; NTSTATUS status = BCryptEncrypt(key_object->key.bcrypt_key, input, insize, &oaepInfo, NULL, 0, output, outsize, result, flags); if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } Now, when calling the connection, it crashes with the error "bcrypt:BCryptEncrypt flags 0x4 not implemented." Can anyone help with enhancing this functionality or at least point me in the right direction?

Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

Post by risele on dynamic modbus devices ^{CODESYS Forge talk (Post)}
Have the same issue: I'm making a test setup for modbus devices testing and calibration. One is run for every possible address, and it starts with minimal request: if the device is found, it continue to work with it, otherwise it's set to Disabled temporary. Those state machines are running under FOR cycle, and disabled are just skipped. Every instance have its own timer for not running too frequently and a start delay, so the actual requests are separate in time. I also check not for a single error, but have some timer to allow one-two timeouts. The small program disables and re-enables devices temporary (manually, since i could not iterate over MB devices). VAR Reset:ARRAY[1..GVL_MB.MD_COUNT] OF R_TRIG; i:INT; END_VAR {IF hasconstantvalue(GVL_MB.MD_COUNT, 1, >= )} i:=1; MD_1.Enable:=GVL_MB.MDPortsEnable[i]; Reset[i](CLK:=GVL_MB.MDPortsEnable[i]); MD_1.xReset:=Reset[i].Q; {END_IF} {IF hasconstantvalue(GVL_MB.MD_COUNT, 2, >= )} i:=2; MD_2.Enable:=GVL_MB.MDPortsEnable[i]; Reset[i](CLK:=GVL_MB.MDPortsEnable[i]); MD_2.xReset:=Reset[i].Q; {END_IF} There is also program to re-enable devices periodically. METHOD ScanBus VAR_INPUT END_VAR VAR j:INT; (*block auto scanning if calibration is running for any device since it's data-reach process that should not be interrupted with modbus timeouts *) CalibrationBusy:BOOL:=FALSE; END_VAR CalibrationBusy:=FALSE; FOR j:=1 TO GVL_MB.MD_COUNT DO CalibrationBusy:=CalibrationBusy OR MD_Calibrate.AutoTesters[j].xBusy; END_FOR; IF CalibrationBusy THEN RETURN; END_IF tBusScanSchedule(IN:=(NOT tBusScanSchedule.Q), PT:=tBusScanPeriod); IF (NOT tBusScanDelayer.Q) AND (tBusScanSchedule.Q OR (NOT xFirstScanPerforemed)) THEN xBusScanBusy:=TRUE; MissingCounter:=0; xFirstScanPerforemed:=TRUE; FOR j:=1 TO GVL_MB.MD_COUNT DO (* MD_Calibrate is main calibration program. Identifiers - is array of State machines mentioned above Phase_Faulted is a state of Identifiers where I'm sure device is missing on the bus *) IF MD_Calibrate.Identifiers[j].state=eStateMDIdentifier.Phase_Faulted THEN MD_Calibrate.Identifiers[j].Rescan(); MissingCounter:=MissingCounter+1; END_IF END_FOR END_IF tBusScanPauser(IN:=tBusScanDelayer.Q AND (MissingCounter>0),PT:=tBusScanDelay*MissingCounter); xBusScanBusy:=tBusScanPauser.Q; xFirstScanPerforemed:=xFirstScanPerforemed OR tBusScanPauser.ET>=tBusScanPauser.PT; Also the GUI have buttons for each address possible that re-enables the device if required.
