Post by tama00 on GPIOs not running with Raspberry Pi 4 (and SPI connection) ^{CODESYS Forge talk (Post)}
Hello everyone, I have a working SPI connection (with transferExt) between a Raspberry master with Codesys and an ESP32 slave. I would also like to use a few GPIO pins. Is there a problem with using SPI AND GPIOs? Environment: Raspberry Pi 4+ with Raspian from Oct 23 Codesys V3.4 SP19 Patch 5 with Runtime Version 4.10.0.0 Device: GPIOs B+/Pi2 My problem: The status is displayed as “GPIOs : not running”. And also during mapping the message “The bus is not running. The values shown are perhaps not actual”. However, the variable changes that I make in my program are displayed under “Current Value”. In the Logic Analyzer, the pin toggles during transmission with small intervals of +-4us (seems to be a cyclical disorder, but I don't know where exactly it could be coming from). This applies to pins that I actually use (output) but also to the other GPIOs (not used). With GPIO 4, the line remains permanently high. Attached is a screenshot from the Logic Analyzer. Channel 1,3,5 were GPIO pin 26, 22, 17 Would be very grateful for help. Best regards

Post by nikgind on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying to import a custom information model that I created using UA Modeler. I have only added two new methods and two new object types. It is possible to add the information model to the Communication Manager and the two new object types are shown in the Information Model tab. After compiling i get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://yourorganisation.org/Bsp_3.1/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway I have installed the information model from 15/12/2023 but not from 15/09/2021. Which makes the error message even stranger.

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
I have a Raspberry Pi 4 we have been using for years to run CODESYS for development purposes. I recently have had to re-install the OS (Raspberry OS lite). The only change to the default configuration is not creating the "pi" user during install. I (apparently successfully) installed the 4.10.0.0 control on the Raspberry Pi. We have licences on a dongle. I am able to start the control. systemctl status shows it as running for a little while (exactly, precisely 30 seconds as per my tests, every time), then it becomes exited. I can restart the control, and the same thing happens again. Every time. In the brief moments it is running, I can log in to the PLC. Working fast and restarting the control many times, I have been able to configure users. I have been able to download my application. I have been able to run the application, and stop on a breakpoint. I have been able to connect with the licence manager and confirm the dongle is detected and licences are listed as OK. I see nothing wrong until the service just exits. I have found nothing in the logs. It is like the runtime just terminates with no error code or message after exactly 30 seconds. Any help would be appreciated.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
So here's how: I manually installed the following packages: codemeter-lite_8.30.6885.501_amd64.deb codesyslicenseserver_licenseserver_4.18.0.0_all.deb codesyswbmbase_wbmbase_4.18.0.0_all.deb codesyswbmlicensing_wbmlicensing_4.18.0.0_all.deb Of course, the license server appeared immediately. Trying to install it again using Install in the Deploy tab, the same error appears. Of course, the information that such a server is already installed is also there. Configuring PLC, S_PLC, EDGE, and SAFE_TIMER_PROVIDER went smoothly, and basically everything works. I wrote a simple program for S_PLC. I'm loading the programs into PLC and S_PLC. When loading the program into S_PLC, a message appears stating that there is no connection to the S_PLC controller. Timeout error. Restart the controller, attempt to load, and see the above. After changing the cycle time for S_PLC to 50ms, the problem no longer occurs. My question, besides the difficulty of installation for a new user, is what causes the cycle time for S_PLC to be so long, and how can I fix it?

Post by tjacks on Opc UA Data Source Client Browse Error in Codesys HMI ^{CODESYS Forge talk (Post)}
Codesys V3.5 SP21 Patch 3 Codesys HMI 3.5.21.30 I'm trying to connect to an OPC UA server on a Kuka robot controller using Codesys HMI's data source manager. I get through the login phase and the client browses most of the data structure on the server but errors out toward the end with a generic: Error while browsing the client, Failed with service result: BadUnexpectedError. If I complete the data source setup and try to update variables, I get the attached stack trace for the error. I've tried several different endpoint and security options. Most get me through the login but all error out while browsing. UA Expert happily connects and browses with the same configuration. I've connected this same version of Codesys to TwinCAT OPC UA servers and Siemens PLC OPC UA servers. Any ideas on what may be causing the generic BadUnexpectedError during OPC UA server browse?

Post by jv-certhon on Io driver Scan functionality ^{CODESYS Forge talk (Post)}
Hello, Codesys IDE is 3.5.21.30 IoDrvBase is: 3.5.17.8 I am working on implementing Codesys on our I/O product line, using the IO driver examples, and the Linux UDS socket approach. I have sucessfully created an implemetation where I have a Device with mutiple slots, on which I can plug modules. These modules represent our IO modules, and communication is successful. (For this question the assumtion can be made that Codesys commucates with 1 'master' device, which handles further communcation with the IO modules. For the next part of the question it can be assumed that the Master device has a list of which modules are attached/available) I'm now trying to implement the 'Scan for Devices...' feature, but I'm completetly lost on what to do once the IoDrvScanModules method is called in my IoDrvFB. I'm guessing that the ppConnectorList has to be filled with the found devices, but I have no idea if that is the correct approach. And Codesys is not triggering my breakpoints in the method, which makes things more difficult. I hope someone could provide some examples or guidance on what steps I should take to implement the scan feature. Thanks in advance.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Yes, this is the error the sometimes show up. What make me crazy is the fact that it happens randomly and not each times. I know very well where the problem is, in wich one program row it's located. For each actions of the state machine I have all events recorded with log on text file. it is not problematic for me to find the application point of the fault, but I need to understand why occasionally and for no apparent reason, switching the state machine and thus changing the motion FB, sends the axis into failure (but only occasionally). For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

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 martinlithlith on Device User Logon and No device is responding.. Pi4b codesys 3.5 SP19 2 + (64-bit) ^{CODESYS Forge talk (Post)}
Hi! Im slowly starting to loose it and i need som help! After a few night of reading up and testing i´m still stuck as a rock and you guys and girls are my last resort for this project. Basic facts; Win 11 Codesys 3.5 SP19 2 + (64-bit) Raspberry pi 4 model b 2 gb Raspian release 11 aarch64 What keeps me up late at night; Username and Password when trying to connect to device and device only beeing connectable for a few seconds. Some of the things I have tried; Username and passord; Credientials from the raspberry Administrator Administrator admin admin Admin Admin administrator administrator Usernames and passwords that I sometimes use (this was a longshot i know, but i was running out of ideas and energy). :) Epand filesystem, activating i2c, spi, 1-wire I can start the gateway and start the runtime. I cant install the edgearm64, arm64 runtime package eventhough I guess i should, i get code [ERROR] Error output: dpkg: error processing archive /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb (--install): [ERROR] Error output: package architecture (arm64) does not match system (armhf) [ERROR] Error output: Errors were encountered while processing: [ERROR] Error output: /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb code as a respons. I have tried to Reset Origin Device - no change. I have tried to remove the /etc/CODESYSControl_User.cfg [CmpUserMgr] but i could not find it and i was not sure if i should add it instead but i did not want to mess somthing up. I have tried to create a second gateway with the specific ip if the pi, that did not help. Could it be that i´m currently connected to the pi through WIFI? I can ping the pi and I can connect and control it through VNC. When i scan to select gateway target (scan edge gateway) i find 17-21 devices but can find the pi throug the mac adress. I started of trying to use the "CODESYS Control for Raspberry Pi SL" (I have a license sience earlier) as i read somewhere that this could be used on a Pi4 as well but now i´m trying with the MC SL, no changes, same problem. Right now - gateway version 4.8.0.0 (edgearmHF, armhf), Runtime Package 4.5.0.0 (raspberry, armhf). Any sugestions are very welcome! As mentioned above, theese are some of the things that i have tried/done - but i have been going at this for a while. Best, Martin

Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I had this code working in a previous version of CoDeSys to read variables from a GVL that were added to the Symbol configuration. The problem now is that when I get the _IBaseTreeNode_Parent, it returns a valid interface, but none of the methods or properties work.

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

Post by mondinmr on COL.IMap2 and HashTableFactory cause frequent Access Violation ^{CODESYS Forge talk (Post)}
Good morning, I’ve been using the Collection library for a long time, mostly with Stack, LinkedList, and List. From your examples I was able to manage the different factories, even for custom elements. Now I need a hashtable, but with this object I’m running into a lot of random access violations. If I append something inside FB_Init after constructing the hashtable, it crashes, even though the list was already created. If I only create the hashtable in FB_Init and append afterwards, it usually works. I don’t understand the meaning of the dispose call in this code: pSlave := ADR(slave); uSlave := TO_ULINT(pSlave); iKey := fKey.Create(uSlave); IF hash.CountKeys() = 0 THEN Service.logger.appendLog('Filling hashtable', 'HashManager', AdvLogType.AdvDebugMsg); ok := FALSE; ELSE eError := hash.ContainsKey(iKey, xResult => ok); END_IF IF NOT ok THEN pI := __NEW(UINT); iVal := fKey.Create(TO_ULINT(pI)); Service.logger.appendLog(CONCAT('New slave', TO_STRING(uSlave)), 'HashManager', AdvLogType.AdvDebugMsg); hash.AddKeyValuePair(iKey, iVal); appendNewSlave := pI; ELSE eError := hash.GetElementByKey(iKey, itfValue => iElem); xResult := __QUERYINTERFACE(iKey, itfIInstance); IF xResult THEN itfIInstance.Dispose(); END_IF IF eError <> COL.COLLECTION_ERROR.NO_ERROR THEN Service.logger.appendLog(CONCAT('ERROR ', TO_STRING(eError)), 'HashManager', AdvLogType.AdvCriticalMsg); appendNewSlave := nullptr; RETURN; END_IF __QUERYINTERFACE(iElem, iVal); {warning disable C0033} pI := TO___UXINT(iVal.UlintValue); {warning restore C0033} appendNewSlave := pI; END_IF Without the dispose call, every second cold reset crashes immediately when I try to access iVal, even if eError doesn’t report any error. With the dispose call, the cold reset issue disappears, but I get other problems: a) If I start the runtime using systemctl start codesyscontrol, it crashes at IF hash.CountKeys() = 0 THEN b) If I delete the files in PlcLogic and download again, it works and survives multiple cold resets. But as soon as I run systemctl restart codesyscontrol, everything gets corrupted again and it starts crashing at that point. FUNCTION_BLOCK SlaveMapCounter VAR hash : COL.IMap2; eError : COL.COLLECTION_ERROR; END_VAR In its FB_Init I create it: METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR hF : COL.HashTableFactory; END_VAR hash := hF.Create(256); In another FB I instantiate it statically: FUNCTION_BLOCK ABSTRACT AbstractServoEthercatController EXTENDS AbstractServoController VAR_STAT hashSlaves : SlaveMapCounter; END_VAR VAR field : REFERENCE TO ADVAbstractFieldUnitEthercatCia402; initCnt : REFERENCE TO UINT; END_VAR The append method is the one shown above, and I call it after the runtime has started. The accesses are performed by a single task, and in any case I’m working on an isolated single core. I’ve tried everything, moving the create, the instances, and all the rest several times, but nothing seems to work. I’d like to point out that these FBs are part of our own library, which is used in many applications.

Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge talk (Post)}
Hi all. I am currently struggling to get my Wago PFC200 running the Codesys Runtime in version 4.9.0.0 working. I am using Codesys V3.5SP19. I updated the PFC200 to the firmware version 04.01.10(23) after having tried the latest version (04.03.03(25) from Wago and not being able to start the runtime. After reading version 23 was needed, I changed to that and at least was able to have it start the codesys runtime. I also installed the "Codesys Control for PFC200 SL 4.9.0.0" plugin for Codesys to install the Codesys runtime in version 4.9.0.0 as well as update the Gateway on the device. While I seem to be able to connect to the gateway on the PLC (the dot is green) and when doing a scan, I do now find my PFC200, which is a huge improvement to before, where with firmware version 25 it just failed to start the runtime and I never found any device when doing a scan. Unfortunately I don't seem to be able to connect to the PLC in codesys. I logged in via SSH and changed the password and I can see that this password is correct as the stuff in the Codesys PFC200 tools tab only works if I use my changed password. And I used those credentials to update the installed Runtime version, which the log claimed to have worked fine. Now whenever I try to connect to the device found in the scan, I get a authentication pop-up with empy device name, device address: 000A. As User I use "root" and as password the password that I changed it to. As a response I just get "Ungültige Benutzerauthentifizierung auf dem Gerät" (Eng. probably something like "Invalid user authentication on the device". What could I be doing wrong? Admittedly I'm a bit lost here :-/ Chris

Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
CODESYS Control for PFC200 4.13.00 CODESYS IIoT Libraries SL 1.11.0.0 Application Based License: CODESYS Control Standard M I have (2) projects with similar code base and both using Wago PFC200. On the second project I am seeing 2 things that I have not been able to resolve: 1) Errors in the log under the Ethernet Item: IoDrvEthernet: [PCI\E1Q51CE62] Could not be found on target! Please check the Ethernet settings. 2) Exception for CPU Load. "Processorload watchdog: plcload=100, maxplcload=95" I have slowed down cyclic tasks on this project, even though on the first project there is actually more code - and it does not exhibit this behavior. In looking at the CPU loading via Linux 'TOP' command there appears to be 20% idle. So plenty of headroom (my opinion). In an effort to troubleshoot I have duplicated the target hardware on my bench. It ran overnight without a CPU load exception. On the test system, I have tried (3) version of the ethernet device. 3.5.16.0 3.5.17.0 and 4.2.0.0 Presently the log does not show the error, but status says the module reports an error. I really do not know if this issue is related to the CPU load exception. The issue does not appear to effect ethernet communications (ModbusTCP or SNMP or Webvisu or PuTTy into Linux Shell). On my test bench I have ModbusTCP slave simulators for all ModbusTCP slaves, but only (1) of the (5) SNMP devices present.

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I am looking for an example of how to run 2 applications on 1 device that would have global variables shared between the two apps. In this case what I am trying to do is to have the main program logic run as one application and then have the visualization run as a second application. I find this https://us.store.codesys.com/media/n98_media_assets/files/000013-F/0/Multiple%20Applications_en.pdf, that talks about exactly what I want to do, but I can't find the download. The main reason I want to do this is for download speed. Right now it takes at least a minute to download our application to the PLC. A simple program downloads to the PLC in a very short time, but add visualization and the download time gets much longer. If I could download the program separately from the visualization I think that a simple program change would take very little time to download. I have tried create a GVL in the POUs view. This partly works in that both applications can see the GVL, but they each create their own instance of it and the variables are not shared between the two apps. There are ideas of using OPCUA but this raises problems with licensing and having to move any variable that needs to be shared into the Symbol Configuration. This adds a lot of management to keep this up to date. Any ideas would be appreciated thanks.

Post by fmon on Modbus : dis- / re-connect cable: modbus does not re-start ^{CODESYS Forge talk (Post)}
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 ? Thanks for your help

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". Is it normal ? 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 client reconnection. What is different at the first client connection and at a reconnection attempt ? Thanks for your help
