Thanks for your quick help. It's working until I do a reboot of the raspberry PI. After that it goes back to 2024-04-20. How's that possible?

I am curious if there is a function block or function that will allow me to monitor the J1939 CANBus and pull out all of the SAs that are on a particular bus, without having to have them loaded in the J1939 manager?

It is either my installation is bad, or there is a bug. I re-created the project in 3.5 SP19 and there are no errors or warnings. Compiles with no errors or warnings. The original was done in 3.5 SP20. Thoughts?

Post by mxj262 on FB having single input but initialized with Array ^{CODESYS Forge talk (Post)}
I am adding elements of an ARRAY using pointer to access each element inside a FOR loop and the FOR loop does not stop! What is the right way to use pointers in such case?? I have another loop that is not using pointer and it stops but the loop using pointer keep on adding. METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: the 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_IN_OUT // basically REFERENCE TO window_buffer: ARRAY [*] OF INT; // array of any size END_VAR THIS^.windowPtr := ADR(window_buffer[0]); THIS^.windowSize := UPPER_BOUND(window_buffer, 1) - LOWER_BOUND(window_buffer, 1) + 1; FUNCTION_BLOCK FB500 VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR windowPtr: POINTER TO INT; windowSize: DINT; currentIndex: UINT; element1:INT; element2:INT; i:INT; j:INT; sum:DINT:=0; END_VAR element1:=windowPtr[0]; // read the first element of the Array dynamic memorry element2:=windowPtr[1]; FOR i:=0 TO (TO_INT(windowSize-1)) BY 1 DO // this loop does not stop Sum:=sum + windowPtr[i]; END_FOR FOR j:=0 TO 5 BY 1 DO // this loop stops j:=j+1; END_FOR https://ibb.co/k3DhkZT

Ok yes now the loop has stopped when I set sum to zero before the for loop. Why will it retain the sum value from the last call?

I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

yes I think you need to build the kernel drivers for the CCAT driver for the backplane ETC networkcard https://github.com/Beckhoff/CCAT/

Post by tortilla on J1939 connection between two devices ^{CODESYS Forge talk (Post)}
Hey, I'm pretty new to CoDeSys so I don't know a lot of things yet. I have to create a connection between two devices (CANbus - J1939 connection). The idea for now is to send a message from one to another (one operates on 3.5 SP11 the other one on 2.3) I watched a few videos, worked with the documentation and worked with chatGPT 4o and was able to build the attached file. This part is about the device on 3.5.11: I'm using the J1939LocalECUDiag, TransmitParameterGroup, TransmissionTrigger Function blocks to send the message but my TransmitPG.xBusy / .xDone never turns to True and therefore my message is not sent while TransmitPG.xExcecute is True. I added the two devices in the CANbus in the J1939Manager and addapted the options like I've seen in the documentation. Can anyone explain what's wrong with my code in this casse or give me advices how to properly create a connection between my two devices? Thanks in advance!

Thanks Edwin. I have reviewed the example and I'm doing basically the same when calling the methods. The recipe files are in the right directory. Everything looks okay but simply it doesn't work. May migrating to Codesys 3.5.20 will solve this?

Hi, which CODESYS IDE version are you using? I think it's fixed in >= SP19 patch 7, maybe also in SP19 patch 6, but I'm not sure.
