Post by paulpotat on Can't open license manager with raspberry CM4 ^{CODESYS Forge talk (Post)}
Hello eschwellinger, Thanks for your answer, with this I was finally able to make it work by doing the following : install CODESYS Control for Linux ARM SL v4.13.0 uninstall CODESYS Control for Linux ARM SL v4.13.0 and make sure to select "yes" when prompted to uninstall WIBU CodeMeter Lite Runtime (v8.10.6230.501) re-install "CODESYS Control for Raspberry Pi SL" v4.13.0 It looks like the issue was probably related to the CodeMeter Runtime ? Best regards

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library. i think the chip was all the time in use by the Raspberry pi itself. Thanks for your help!

Ok, for the sake of completeness in case anyone else has this problem. I can tell you that what finally worked for me was to change the line: // create an ExtensionObject to wrap the value to be written ExtensionObject extensionObject = new ExtensionObject( new ExpandedNodeId("GVL_StructA", 5), structAData ); to: // create an ExtensionObject to wrap the value to be written ExtensionObject extensionObject = new ExtensionObject( new ExpandedNodeId("GVL_StructA|defaultbinary", 5), structAData ); I'm sure there are many other problems that could cause this very generic error, but this was my problem.

Post by alex2 on How to uninstall SVN module ^{CODESYS Forge talk (Post)}
Hello, At work, I use Codesys V3.5 SP10. I wanted to run some tests with the SVN module, which I kept installed (without actually using it in the end). However, when I tried to launch Codesys today, I was informed that a license was missing. I suspect that this is due to the SVN module. Could you tell me how to uninstall it without launching Codesys? (as i cant proprerly start Codesys without the license) Thank you in advance.

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Hi Trusty-Squire, just seen you post , thanks for the reply. I was out on site the other day as it had done it again and changed a few things like cycle time etc. plc load is only 7% at its highest. I took a few screenshots while i was there to add to this post. its been up for about a week now but seems to happen at random every couple of weeks. fingers crossed!

Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Post by lbouchard on CANOpen SIL2 error: UNSAFESTACK_NOT_OPERATIONAL ^{CODESYS Forge talk (Post)}
Update: I still have no idea what was causing my issues, but it went away as soon as I identified that another device on the CAN was generating a Sync message at 16#7F. Changing this to be on 16#80 made the problem go away. I have no idea why this solves the problem and would love to hear from anyone who knows why these two things might be related.

Post by josul on Web Client HTTPS Communication Issue ^{CODESYS Forge talk (Post)}
Thank you for the suggestion. There is a certificate created in the quarantine directory relating to the URL used for the webclient FB. This certificate should have been valid as it was created only the week before this problem was encountered. I investigated a separate location using the same https URL and it has 2 certificates in the same quarantine directory, 1 is created almost 200 days ago, the other over 100 days ago. There have been no similar problems encountered with these certs or https at all.

Post by timl on BacNet Server ^{CODESYS Forge talk (Post)}
Hallo, für einen BacNet2 Server lassen sich mit zwei Ethernet Schnittstellen auch zwei Bacnet 2 IP Datalinks anlegen. Einen Datalink nutze ich für den UDP Port 47808 und einen für den UDP Port 47809. Dadurch ist der Server aus beiden Netzwerken erreichbar, was so gewollt ist. Allerdings verbindet er die beiden Netze auch miteinander, was zu Kommunikationsproblemen führt, da in beiden Netzwerken bereits gleiche Device ID's vergeben sind und diese sich dann doppeln. Lässt sich diese Verbindung der beiden Netze abschalten? Gruß Tim

It was not easy but I found this :) https://forge.codesys.com/tol/c2iec/home/Home/ Does anybody use it for a programm/library of a couple of hundred lines or more? How does one go about using the output? Is there a “converter” into the Codesys IDE? PLCOpenXML? Would there be interest in this? tib0r

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?

Okay, the solution was so simple... In my case, you first have to add the EL1918 and then the EL2904... then the connection is made automatically. I probably had something else before and then added the EL1918... then it doesn't catch the connection :/
