Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by mariussandu on OPC-UA ^{CODESYS Forge talk (Post)}
Hello, I am experiencing an intermittent OPC UA server issue on CODESYS Control for Raspberry Pi SL 4.21.0.0. Runtime information: codesyscontrol 4.21.0.0 Raspberry Pi 4 Model B Rev 1.1 - 4Gb OPC UA Server: CmpOPCUAServer 3.5.22.x Server IP: 192.168.0.110 OPC UA endpoint: opc.tcp://192.168.0.110:4840 The main OPC UA client is Node-RED running on 192.168.0.111. This has an active subscription with some tags and also some write functions active. The system normally works correctly for a period, but at some time the OPC UA communication stopped. Node-RED started reconnecting continuously but could not reconnect. I also tried connecting using UaExpert, but UaExpert returned: BadTimeout At the same time, the PLC application itself was still running. Before restarting CODESYS, I captured the TCP connections. The OPC UA server was still listening: tcp 11 0 192.168.0.110:4840 0.0.0.0:* LISTEN However, there were many connections from the Node-RED client stuck in CLOSE_WAIT: 192.168.0.110:4840 192.168.0.111:45008 CLOSE_WAIT 192.168.0.110:4840 192.168.0.111:53678 CLOSE_WAIT 192.168.0.110:4840 192.168.0.111:44032 CLOSE_WAIT 192.168.0.110:4840 192.168.0.111:36612 CLOSE_WAIT 192.168.0.110:4840 192.168.0.111:45012 CLOSE_WAIT 192.168.0.110:4840 192.168.0.111:36592 CLOSE_WAIT ... Some of these sockets also had data remaining in Recv-Q, for example: Recv-Q = 61 Recv-Q = 121 There were roughly 15–20 OPC UA connections in CLOSE_WAIT. Restarting only the CODESYS runtime immediately restored OPC UA communication. After restart: LISTEN 0 10 192.168.0.110:4840 and both Node-RED and UaExpert can connect normally again. There are no obvious OPC UA errors during startup or in log. On RPI 2 I had a memory leak regarding OPCUA so I had to upgrade to RPI4. What can I do in this case? Thank you!

Post by darko7417 on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
I run CODESYS runtime as a service and use CmpLog (the LogAdd2 function) to log different events to a file. I have done this many times before on various projects and hardware, and it works fine. On this particular system, I have CODESYS 3.5.20.40 running on a Windows 11 PC. The CODESYSControlService autostarts (with Local System credentials, the default), and the application runs fine. However, the configuration file is not read (or at least not the one that should be, or not the CmpLog section), and log files are not written to the disk. I would be thankful if anyone knew why this is happening and how to fix it. A note to CODESYS people: you must provide more information on the codesys configuration file, CODESYSControlService.exe and other major components and system behaviour. You created the service and various features (i.e. logging), but haven't explained how they work, which, in my opinion, is below standard for industrial automation software. These are my observations: - When running as a service, the config file is not read (none of them), or at least the CmpLog section is not read. I checked the log using Codesys IDE, and the CmpLog parameters are not the ones I have set in any of the config files. Which CmpLog config values does the service use, and where does it read them from? I have no idea, but it's not the config files. Here are the codesys config files I located on the PC's disk: o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControl.cfg (only 2 lines in this config) o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\AppDataFiles\CODESYSControlWinV3\CODESYSControl.cfg o C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\tempCFG\CODESYSControl.cfg - When I run codesys as an app (e.g. by clicking the icon), this config file is read C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg and log files are written ok. The icon target is "C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControlService.exe" -d o the -d option, I think, starts a cmd-like window showing service debug output (the output shown in log in the IDE) o the -i option, again I think, means install the service - I tried adding -d to service start parameters in the registry, but it started only once and after that it refused to start. Knowing what -d does and which other options are available would be great (e.g. can I make the service read a different config file). - Syslog UDP logging works fine in any case. - These are my CmpLog parameters ~~~ [CmpLog] Logger.0.Name=PlcLog3 Logger.0.Filter=0xFFFFFFFF Logger.0.Enable=1 Logger.0.MaxEntries=10003 Logger.0.MaxFileSize=50003 Logger.0.MaxFiles=33 Logger.0.Backend.0.ClassId=0x0000010B ;sends logger messages to SysOut Logger.0.Backend.1.ClassId=0x00000104 ;writes logger messages in a file Logger.0.Backend.2.ClassId=0x00000135 ;sends logger messages as UDP syslog Logger.0.Type=0x314 ;Set the timestamp to RTC ~~~

Post by scoob on ModbusFB - Slow Response Time ^{CODESYS Forge talk (Post)}
Hello, I have been trying to use the ModbusFB functions so I can put some code into libraries, but it seems to be very slow for me. I have a Modbus device with 100ms registers. I previously setup 10 channels in the 'traditional' Modbus Slave with channels and mappings - and set a cyclic trigger at 100ms - this worked fine. I then tried the ModbusFB example, and setup reading the same 10 blocks of modbus addresses, copying the example and putting all of the requests into an array and triggering the requests sequentially. I timed how long the requests are taking to get round to each one, and it is around 1s 450ms. How do I speed this up to match the cyclic time? IF NOT(init) THEN init := TRUE; // Set the required IP address: ipAddress[0] := 192; ipAddress[1] := 168; ipAddress[2] := 1; ipAddress[3] := 10; // Pass the required IP address to the clinet FB: client_NetworkSwitch.aIPaddr := ipAddress; client_NetworkSwitch.udiLogOptions := (ModbusFB.LoggingOptions.ClientConnectDisconnect OR ModbusFB.LoggingOptions.ClientReceivedValidReplies); // Try to connect the client client_NetworkSwitch(xConnect:=TRUE); // Configure all the channels to read connecting them to the client: portStatus_Request(rClient := client_NetworkSwitch, uiStartItem := 4096, uiQuantity := 32, pData := ADR(portStatus), udiReplyTimeout := udiReplyTimeout); portSpeed_Request(rClient := client_NetworkSwitch, uiStartItem := 4352, uiQuantity := 32, pData := ADR(portSpeed)); flowControl_Request(rClient := client_NetworkSwitch, uiStartItem := 4608, uiQuantity := 32, pData := ADR(flowControl)); linkUpCounter_Request(rClient := client_NetworkSwitch, uiStartItem := 5888, uiQuantity := 32, pData := ADR(linkUpCounter)); txPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8192, uiQuantity := 100, pData := ADR(txPacketCounter1)); txPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8292, uiQuantity := 28, pData := ADR(txPacketCounter2)); rxPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8448, uiQuantity := 100, pData := ADR(rxPacketCounter1)); rxPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8548, uiQuantity := 28, pData := ADR(rxPacketCounter2)); txErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8704, uiQuantity := 64, pData := ADR(txErrors)); rxErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8960, uiQuantity := 64, pData := ADR(rxErrors)); // Trigger all client requests initially FOR clientRequestsCnt := 0 TO (SIZEOF(clientRequests)/SIZEOF(clientRequests[0]))-1 DO pClientRequest := clientRequests[clientRequestsCnt]; pClientRequest^.xExecute := TRUE; END_FOR // Prepare sequential trigger / control of client requests. clientRequestsCnt := 0; pClientRequest := clientRequests[clientRequestsCnt]; END_IF // Call the client to do request processing: client_NetworkSwitch(); // Now we trigger client request sequentially ... IF NOT pClientRequest^.xExecute AND NOT pClientRequest^.xDone AND run AND client_NetworkSwitch.xConnected THEN pClientRequest^.xExecute := TRUE; END_IF // .. and check result/error IF pClientRequest^.xExecute AND run AND client_NetworkSwitch.xConnected THEN IF pClientRequest^.xDone THEN // Prepare next trigger of client request (a rising edge of xExecute) pClientRequest^.xExecute := FALSE; IF clientRequestsCnt < SIZEOF(clientRequests)/SIZEOF(clientRequests[0])-1 THEN // next client request clientRequestsCnt := clientRequestsCnt + 1; ELSE clientRequestsIterationCounter := clientRequestsIterationCounter + 1; clientRequestsCnt := 0; END_IF pClientRequest := clientRequests[clientRequestsCnt]; END_IF END_IF I did try a semi-coded way using the IoDrvModbusTCP library, and setting the slave com settings, then 10 commands and 10 requests, then using a TP on xDone as a pause, before triggering another request - this is time the delay is around 120ms - so the device is fine with the speed, just something I am doing wrong in the ModbusFB method I am sure.

Post by bschraud on Speicherbegrenzung für lokale Variablen ^{CODESYS Forge talk (Post)}
Aufgrund einer Schnittstellenänderung muss ich meine Messagebuffer erheblich vergrößern. U.g.

Post by george32 on CSV file and string manipulation. ^{CODESYS Forge talk (Post)}
Dear folks, I think I have a rather simple question but I could not find the right answer to my question: I have made with Excel a CSV file where I would like to have some general data regarding my program variables. I have made an program what let me read the file. The string I am currently get is at follows: 'IP_Adres;192.168.45.12$R$NPort_number;2000$R$NCycle_time;43$R$NStart_Standard_IO;20$R$N' Now I want to split the string in multiple part, which I later would connect to the right variable. By Google and experimenting I have reached to the following code for the first part of the splitting proces: // Splitting the BOM of the string: Received_string := FileReadString; IF LEFT(STR:=New_string,3)= '' THEN Received_string_without_BOM :=RIGHT(STR:= Received_string,SIZE:= (LEN(STR:= Received_string))-3); END_IF //Splitting the remaining string in part for later declaration. WHILE index = 0 DO index_split_part := FIND(STR1:= Received_string_without_BOM,STR2:= '$R$N'); Part_of_String[index]:=LEFT(STR:=Received_string_without_BOM, SIZE:= index_split_part); index := index + 1; END_WHILE However in the splitting proces I could not understand what is really happening. I understand that the Find() function returns the first value the $R$N in the Received_string_without_BOM. This would mean that the index_split_part := 23 I|P| _ |A |d|r|e|s|;|1_|9 |2 |. |1 |6 |8 |. |4 |5 |. |1 |2 |$ |R |$ |N |P | 1|2| 3 |4 |5|6|7|0|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27| So the next part is to read the first 23 characters of the Received_string_without_BOM with the LEFT() function. I expected that the outcome the following was: 'IP_Adres;192.168.45.12$'. However the outcome is: 'IP_Adres;192.168.45.12$R'. I do not understand where the R after the $ sign comes from, because its place is 24 so it would not be added to the part_of the_string[index]. If I hard coded value 24 for the size it gives me the following return: 'IP_Adres;192.168.45.12$R$N'. I would expect everything till the R but the code adds the $N also to the string. I hope someone could explain to my what I am seeing wrong in my point of view? With kind regards, George

Post by gilbert-mh on CAA net base TCP client cause PLC to crash - Kernel message : N0HZ_local_softirq_pending 80 ^{CODESYS Forge talk (Post)}
Hello all, I have been trying to implement a TCP client on a Festo PLC (CPX-E-CEC-M1) and it looks like it works well except that after some time (greatly varies between a few hours to more than 100h) my PLC crash. When I look into the log file the only thing I see is that before the crash happens a few kernel warnings : N0HZ_local_softirq_pending 80 and then the crash. I've looked into this warning and from what I could find on the net it seems that this is warning is triggered when the ethernet link is down. I've tried to correct this bug for quite some time and what I know is that : - The crash is caused by my TCP client, when I remove it from my code I see no crash - The crash happens more quickly the more the TCP client is used. - The time before the crash is not directly proportional to the number of communications or their size. But it looks like it is just more likely to happen if the client connect to the server at a higher frequency. - The precedent observation makes it seem unlikely that the crash is caused by some memory overflow because then the crash speed would be more proportional to the amount of data exchanged. SO from these observations, I believe that the crash could be caused by the PLC trying to connect to a server while there is some kind of issue with the ethernet link resulting in the PLC getting stuck in some indefinite state and making it crash. This still seems a bit unlikely to me because if the ethernet is down it simply shouldn't be able to contact the server and the communication would just fail which doesn't cause my PLC to crash. Has anyone encountered the same kind of problem (with the same kernel message) ? I am pretty sure the warning is not the direct cause of the crash but just an indicator that something is wrong with my PLC. Thanks in advance

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Hi, everyone! I'm trying to set up a PLC controller and a connection to an EtherCAT slave device in Codesys. I want to create a flexible program that I can upload to multiple controllers with different remote IO connected (same program). On one plant i may have 5 AI-cards and 3 DO-cards, and on another I may have 4 AI-cards and 2 DO-cards. For not needing to maintain several different programs wih different devices defined in the program (one for each set up) I thought that using a remote IO would make it easier having a single program. That way I could refer to different memory addresses instead of predefined slots/channels and IO's, that would give me errors if there was a different IO on the plant than what the program expected. When I tried setting up the etherCAT master, I saw that I had to define the etherCAT slave devices with the different IO'cards for me to be able to refer to the memory addresses in a PRG. Exactly what I was trying to avoid. My setup is something like a program that can handle 16 separate pump controls. In a year maybe 6 plans get deployed, and depending on how large the project is, the number of pumps can vary between 4 and 16. And the managers dont want to have IO's for all 16 pumps on every cabinet, and I dont want to maintain 16 separate projects files in case of updates etc. I thought the best way to tackle this was having a single project that read/write data to the different pump IO's by remote IO (fieldbus ethercat) addresses. And the number of pump controls are activated by an external GUI. If pump 1-6 is activated by the GUI, then the PLC-program tries to read/write input/outputs from predefined addresses for the expected IO's. My test setup is a PFC200 WAGO controller and a EtherCAT fieldbus coupler (750-354) with some IO. I hope I didn't explain this too horrible, and if there is a more easy and elegant solution for this challenge I appreciate a feedback on this.

Hi, I am trying to load a test application into a DSE M840-001-02 display, but after reboot the device still shows: “No application loaded” I would like to understand whether the problem is in my project, the package creation process, or firmware/runtime compatibility.

My questions If DSEServiceTool shows Status OK and package ACK, but the device still says “No application loaded”, does that mean: the .pkg was transferred but not accepted as a valid application? the package was built incorrectly? the boot application / runtime / firmware versions are still mismatched? What is the correct procedure to generate CodesysApp.pkg for M840-02 V4.1? Is there any known compatibility issue between: DSE CODESYS Package 1.5.44 M840 MKII Firmware 4.1.2 CODESYS 3.5 SP12 Has anyone successfully loaded even a minimal empty test project into M840-001-02, and if so, what exact versions/process did you use?

Post by rossanoparis on CAN TX regression in Control for Raspberry Pi 4.21.0.0 with CAN API library (RX works, TX silently fails) ^{CODESYS Forge talk (Post)}
Environment: Target: Revolution Pi (Kunbus RevPi), armv7l 32-bit OS: Raspbian GNU/Linux 9 (Stretch), kernel 4.19.95-rt38-v7 (SMP PREEMPT RT, built 2022-03-22) CAN: via SocketCAN (can0) Runtime: CODESYS Control for Raspberry Pi SL IDE: CODESYS V3.5 SP22 + patch 3 (previously V3.5 SP22 + patch 2, where everything worked with runtime 4.18.0.0) Library: CANBusAPI from the "CAN API" package, version 1.0.0.3 Summary: The setup worked correctly with V3.5 SP22 + patch 2 and runtime 4.18.0.0. After updating the IDE to SP22 + patch 3 and the runtime to 4.21.0.0, CAN transmission via the CANBusAPI library stopped working. Reception is unaffected. There are no error indications anywhere: the application runs normally and the CAN diagnosis reports a healthy bus. Systematic testing (below) shows the problem follows the runtime version, not the IDE update. Regression isolation: The same application (compiled under SP22 + patch 3, unchanged between tests) was downloaded to the same target with different runtime versions, changing only the runtime each time: 4.18.0.0: TX and RX both work 4.19.0.0: TX and RX both work 4.20.0.0: TX and RX both work 4.21.0.0: RX works, TX does not The behavior is fully reproducible in both directions (downgrading to 4.20 restores TX, upgrading to 4.21 breaks it again). Hardware, wiring, OS, project, and application code are identical across all tests. Diagnostic data (CANBusDiagnosis FB, while the application is transmitting on 4.21): ctSendCounter: incrementing normally ctTxErrorCounter: 0 ctRxErrorCounter: 0 eState: ERROR_FREE xBusAlarm: FALSE So the library accepts and counts the outgoing messages, no TX errors are reported, and the CAN controller state stays error-free, but the messages never reach the other nodes on the bus. Expected behavior: Messages sent via CANBusAPI (CANDriver / SendMessage) are transmitted on the bus, as with runtime versions up to and including 4.20.0.0. Notes: I am aware that the CAN API package (1.0.0.3, from 2016) is old; however, the regression is tied to the runtime version, since the identical binary works on 4.18-4.20. Questions: Is there a known change in CmpSocketCanDrv / CmpCAACanL2 between 4.20.0.0 and 4.21.0.0 that could affect TX via the CAN API library? Is runtime 4.21.0.0 still supported on Debian 9 Stretch (kernel 4.19, RT-patched), or is a newer OS required? If a minimum OS/kernel requirement was introduced with 4.21, is it documented?

Post by paulg on RasPi CAA Serial example - unexpected behavior during debug ^{CODESYS Forge talk (Post)}
I've trimmed down the CAA Serial Codesys example to only listen on one port but, when stepping through the Case structure in debug mode, it jumps out of the structure during a specific point in every scan (I'll point it out below after describing the setup and listing the code). I'm using a Pi 4 Model B, and I have an Arduino Nano Every plugged in via USB which is streaming the following serial message at 1 Hz: Time since opening connection: 1 s Time since opening connection: 2 s ...and so on. The Pi shows the Nano at /dev/ttyACM0 so I edited CODESYSControl_User.cfg to read: Linux.Devicefile=/dev/ttyACM The code in my PLC_PRG is (ignore some of the comments, I hadn't deleted them out from the original example): PROGRAM PLC_PRG VAR xStartTest : BOOL:= TRUE; iState : INT; xTestDone : BOOL;(* True, when the test was done succesfully *) (* Settings to communicate with the COM Port *) aCom1Params : ARRAY [1..7] OF COM.PARAMETER; como1 : COM.Open; comc1 : COM.Close; comw1 : COM.Write; comr1 : COM.Read; //sWrite : STRING := 'Test String!'; sRead : STRING(25); szRead : CAA.SIZE; xCom1OpenError : BOOL; xCom1CloseError : BOOL; xCom1WriteError : BOOL; xCom1ReadError : BOOL; END_VAR //This example shows the communication of two COM Ports with each other. //The first one writes a string of characters, which is read by the second one. //After successful execution, the two COM Ports are closed and the test is done. IF xStartTest THEN CASE iState OF 0: //The parameters are set for the COM Port aCom1Params[1].udiParameterId := COM.CAA_Parameter_Constants.udiPort; aCom1Params[1].udiValue := 1; // the correct Port should be adapted aCom1Params[2].udiParameterId := COM.CAA_Parameter_Constants.udiBaudrate; aCom1Params[2].udiValue := 115200; aCom1Params[3].udiParameterId := COM.CAA_Parameter_Constants.udiParity; aCom1Params[3].udiValue := INT_TO_UDINT(COM.PARITY.NONE); aCom1Params[4].udiParameterId := COM.CAA_Parameter_Constants.udiStopBits; aCom1Params[4].udiValue := INT_TO_UDINT(COM.STOPBIT.ONESTOPBIT); aCom1Params[5].udiParameterId := COM.CAA_Parameter_Constants.udiTimeout; aCom1Params[5].udiValue := 0; aCom1Params[6].udiParameterId := COM.CAA_Parameter_Constants.udiByteSize; aCom1Params[6].udiValue := 8; aCom1Params[7].udiParameterId := COM.CAA_Parameter_Constants.udiBinary; aCom1Params[7].udiValue := 0; //The first Port is opened with the given parameters como1(xExecute := TRUE, usiListLength:=SIZEOF(aCom1Params)/SIZEOF(COM.PARAMETER),pParameterList:= ADR(aCom1Params)); IF como1.xError THEN xCom1OpenError := TRUE; iState := 1000; END_IF //After a successful opening, the next state is reached IF como1.xDone THEN iState := 15; END_IF 15: // the reading process is started comr1(xExecute := TRUE,hCom:= como1.hCom, pBuffer:= ADR(sRead), szBuffer:= SIZEOF(sRead)); IF comr1.xError THEN xCom1ReadError := TRUE; END_IF //After completion the size of the written bytes are saved IF comr1.xDone OR comr1.xError THEN szRead := comr1.szSize; iState := 20; END_IF 20: // If everything was successful the ports are closed and the handles are released comc1(xExecute := TRUE,hCom:= como1.hCom); IF comc1.xError THEN xCom1CloseError := TRUE; END_IF IF comc1.xDone OR comc1.xError THEN iState := 25; END_IF 25: // The first port is closed and the used handle released xTestDone := TRUE; xStartTest := FALSE; iState := 0; como1(xExecute := FALSE); comw1(xExecute := FALSE); comc1(xExecute := FALSE); ELSE iState := 0; END_CASE END_IF I realize as I write this that the .udiPort should be 0 and not 1, but that shouldn't be causing the issue I'm seeing. I'm forcing xStartTest:=TRUE every scan so that I can step into each line and observe what's happening. What I see is that the port parameters are set and the port is opened with no errors, but the code jumps out of the case structure to the last line every time it reaches (and I step into) the iState:=15 line (at the end of the iState:=0 block). So every scan cycle it goes through the block for iState=0 and jumps out at the same spot. I'm a little new to PLC programming so I may be misunderstanding the flow, but shouldn't this case structure keep moving down in the same scan? If it only handles one case per scan, why doesn't the value of iState persist? Thanks! Update: I restarted the Codesys control today and I was then able to see an error for como1.eError of "WRONG_PARAMETER". I tried doing some digging and another post made me think I should add another line to CODESYSControl_User.cfg, so I now have: [SysCom] Linux.Devicefile=/dev/ttyACM portnum := COM.SysCom.SYS_COMPORT1 So now when I set .udiPort to 1, I get "NO_ERROR" but I also don't read anything from the port (i.e. szRead = 0 always). If I try setting the port to 0 (which I'm confused about, because I added a COMPORT1 line but the device shows on the Pi as ACM0), I get the "WRONG_PARAMETER" error again. Is there an easier way to troubleshoot the Pi and view what ports the Codesys runtime is actually able to see while the Pi is running?

Post by baltzer on ICertificateVerifier.VerifyCertificate doesn't appear to override an ERR_CERT_HAS_EXPIRED rejection in TCP_Client.Upgrade() ^{CODESYS Forge talk (Post)}
Setup: Net Base Services (NBS), TCP_Client + TLSContext, ePurpose := CLIENT_SIDE, connecting to a third-party embedded device (Velux KLF200 home automation gateway) whose factory-installed TLS certificate expired on 2026-07-12 and has no user-facing renewal path. Tested on both CODESYS Control for Raspberry Pi SL (3.5.19.0) and CODESYS Control Win V3 x64, with identical results on both. Goal: Accept the peer's expired certificate via a custom ICertificateVerifier implementation, since the certificate itself can never be replaced. Implementation: FUNCTION_BLOCK FB_MyCertVerifier IMPLEMENTS NBS.ICertificateVerifier VAR udiCallCount : UDINT; aeCurStateLog : ARRAY[0..9] OF NBS.RTS_IEC_RESULT; END_VAR METHOD VerifyCertificate : UDINT VAR_INPUT hCert : NBS.RTS_IEC_HANDLE; eCurState : NBS.RTS_IEC_RESULT; END_VAR IF udiCallCount < 10 THEN aeCurStateLog[udiCallCount] := eCurState; END_IF udiCallCount := udiCallCount + 1; VerifyCertificate := 0; // also tried: VerifyCertificate := eCurState; Wired in via tlsContext.itfCertVerifer := certVerifier at declaration time, alongside itfTLSContext := tlsContext set at TCP_Client's own declaration (per an earlier forum thread here on ensuring inline start-values on FB-typed variables are actually honored when nested one level deep - that fix was needed and worked correctly for getting the handshake to start at all). Observed: - VerifyCertificate is confirmed called exactly once per connection attempt (via the call counter above). - eCurState passed in = 0x709 = ERR_CERT_HAS_EXPIRED - correctly reflecting the actual state of the peer's certificate. - Packet capture confirms the full TLS 1.2 handshake completes correctly at the wire level: ClientHello -> ServerHello -> Certificate -> ServerKeyExchange -> ServerHelloDone -> our ClientKeyExchange/ChangeCipherSpec/Finished -> server's ChangeCipherSpec/Finished. Both sides successfully complete the cryptographic handshake. - Despite this, TCP_Client.Upgrade() subsequently returns NBS.ERROR.CONNECTION_ERROR, and the connection is torn down with a plain TCP FIN (not a TLS alert) roughly 7-8ms after our side ACKs the server's Finished message. - TCP_Client.eErrorID (inherited from LCon) remains NO_ERROR throughout - the failure is only visible via Upgrade()'s return value. - Returning 0 (ERR_OK/ERR_CERT_OK - confirmed via the CmpErrors2 Interfaces documentation that these are literally the same value) makes no difference. - Echoing eCurState back unchanged (on the theory that this callback might work like mbedTLS's native verify callback, where the incoming state is a flags value to be cleared/modified and returned, rather than paired with a separate fixed "accept" sentinel) also makes no difference. - Identical result across udiVerificationMode := 0, 1, and 2. - Importing the peer's certificate into the runtime's trusted certificate store via cert-import trusted makes no difference either. - With itfCertVerifer left at its default (no custom verifier) and udiVerificationMode := 2, the underlying engine sends its own fatal TLS alert (handshake_failure) immediately after receiving the peer's Certificate message - suggesting built-in validation may reject at the record layer independent of whether a custom verifier is even present. Questions: 1. Is there an additional step required for a custom ICertificateVerifier to actually override an ERR_CERT_HAS_EXPIRED (or more generally, any ERR_CERT_*) rejection, or is certificate validation enforced unconditionally for a CLIENT_SIDE TLSContext regardless of what the verifier returns? 2. Is 0/ERR_OK genuinely the correct "accept" return value for VerifyCertificate, or does it expect something else (a specific bit pattern, a different constant, a value that must be computed from hCert itself)? 3. Is there a supported way to connect to a peer presenting a certificate that is both self-signed and expired, short of the peer issuing a new certificate? Happy to share the full packet captures or additional test combinations if useful. Also worth noting for anyone finding this thread later: a maintained Node-RED library for this same device (node-red-contrib-velux-klf200, forked to handle this exact expired-certificate situation) solves it by disabling built-in TLS validation entirely (rejectUnauthorized: false) and doing fingerprint-based pinning by hand after the handshake completes, rather than relying on a validation callback - which may be the more realistic approach here too if ICertificateVerifier genuinely can't override this class of rejection. Thanks in advance /Jørgen Disclosure: most of the CODESYS code and this investigation was developed with the help of Claude (Anthropic's AI assistant) - the state machine design, SLIP/checksum implementation, and debugging methodology (including the packet capture analysis) were worked through in an extended back-and-forth with it. Posting here because we've run out of self-serviceable options and this now looks like it needs input from someone with visibility into NBS's actual implementation.

Post by kuegerls on PROFINET Controller SL: WRREC remains BUSY forever, no DCE/RPC packets transmitted (RevPi Connect 5 + NORD SK205E) ^{CODESYS Forge talk (Post)}
Hello , I am currently evaluating the CODESYS PROFINET Controller SL on a Revolution Pi Connect 5 and have encountered a problem with acyclic PROFINET Record Access (WRREC/RDREC). System Hardware: Revolution Pi Connect 5 Runtime: CODESYS Control 4.16.0.0 (SDK 3.5.21.10) Development System: CODESYS V3.5 SP21 (64-bit) CommFB: 3.5.17.10 ProfinetCommon: 4.6.0.0 PROFINET Controller Device: PN-Controller 4.6.0.0 PROFINET Device: NORD DRIVESYSTEMS SK205E with SK TU4-PNT GSDML: GSDML-V2.46-NORDDRIVESYSTEMS-PNT-20251016.xml Network The PROFINET network is completely separated from the office network. RevPi: eth0 → Office network eth1 → PROFINET wlan0 → Visualization The PN Controller is configured to use eth1. IP configuration: RevPi (eth1): 192.168.100.1/24 NORD Drive: 192.168.100.3 Connection is established successfully. Current Status The PN Controller reports: Controller Status = Run Online = TRUE IP Active = TRUE Connections = 1 Cyclic PROFINET IO communication works correctly. Problem I am trying to access PKW parameters via WRREC (Record Index 100). The request buffer contains: 01 14 00 04 92 00 00 00 00 00 00 which corresponds to Reference = 0x01 Request = Read Axis = 0 Parameter = 170 + 1000 Subindex = 0 Value = 0 The WRREC call is fbWRREC( REQ := xWrReq, ID := ConnectionID, INDEX := 100, LEN := 11, RECORD := ADR(TxBuffer) ); REQ is pulsed for one PLC cycle only. Observed Behaviour WRREC enters BUSY state and never finishes. Observed values: BUSY = TRUE DONE = FALSE ERROR = FALSE STATUS = 16#FFFFFFFF indefinitely. Packet Capture A Wireshark capture was taken on the PROFINET network. Observed traffic: PROFINET RT LLDP DCP Observed: successful cyclic IO Not observed: DCE/RPC Record Write Record Read RPC Bind No RPC packets are transmitted at all. Diagnostic Messages The controller repeatedly reports AR alarm.ind(err) AR CMI timeout although cyclic IO communication continues to work. Already Verified The following points have already been checked: correct Ethernet interface (eth1) correct CREATE_ID result correct Device ID correct Slot/Subslot correct GSDML correct REQ pulse RECORD buffer is larger than LEN cyclic IO communication works different Record Indices (100...104) tested Question Is there any known issue or limitation where WRREC/RDREC requests remain permanently BUSY and no RPC Record Access packets are generated? Could this behaviour be related to Runtime 4.16.0.0, PN Controller 4.6.0.0, the missing runtime license (currently running in demo mode), or any known issue with the PROFINET Controller SL? I am currently evaluating the PROFINET Controller SL and therefore the runtime is operating in demo mode. Could you please confirm whether WRREC/RDREC (acyclic Record Data services) are fully supported in demo mode, or whether a valid license is required for these services? If required, I can provide: complete project archive Wireshark capture (.pcap) GSDML online screenshots diagnostic log Thank you very much for your help. Best regards, Stefan
