Steps to use the serial port on the CC100 with NodeRED in Docker. Disable the PLC Runtime [image] The serial port on the CC100 is called /dev/ttySTM1 and has the correct permissions by default. [image] Install Node-RED and attach the serial port in privileged mode. docker run -d --name…

NodeRed CC100 Modbus RTU: please do the following steps: stop the container delete the container and volume start the container new enter the container and build node-red-contrib-modbus new docker stop node-red docker rm docker volume rm node_red_user_data docker run --name wago-node-red --p…

Hi there Kurt, Thank you for the informative post. I was wondering if this is the same situation for the Wago PFC200 controllers? If so, how does one read up on the devices and there names? For example here the serial port is “/dev/ttySTM1”. Is this information freely available somewhere? Additio…

Just for a bit more information, here is a copy of the email I sent to Wago’s support for some more context of the issue. I have a pfc200, 8216 controller. I have been able to successfully run Modbus tcp/ip communication with a power meter in Node-RED. I’m now trying to do the same but with Modbus…

Please see this post; [image] How To: Using PFC200 Onboard Serial Port with Node-RED Node-RED To change the serial port mode you can use the command line tool found in /etc/config-tools directory called set_serial_mode. cd /etc/config-tools/ To use RS485 (default): ./se…

@WagoKurt thank you very much for the response, it has helped my understanding a lot. I have since set port ttyO1 to rs485 by using the command line tool (/etc/config-tools ./set_serial_mode_rs485). I also ensured that the necessary r+w permissions were allowed to ttyO1 for read and write access to …

Can you verify what containers are running with the command; docker container ls I would ensure only one container is running for the initial testing of the serial port. And also can you confirm that the Codesys runtime is disabled.

@Devlin_Hugo @WagoKurt I am experiencing a similar issue on my wago CC100 running node red in docker. I’ve spent the last couple of days trying to solve this but with no positive outcome. Even with only one modbus serial read node and a debugger, after configuring the modbus read node, node red imm…

Maybe something is helpful here with udev/symlinks: serialport permissions opened 01:52PM - 13 Mar 23 UTC (UTC) [thorgrimjansrud] thorgrimjansrud inf…

Thank you for responding @WagoKurt and @StefSoma . I can confirm that the runtime on the controller has been disabled. Each time Node-RED has crashed I have stopped and removed the container using the “docker stop containerID” and “docker rm containerID”. I would then run the “docker container ls” c…

@WagoGrim Thank you for the guidance. Unfortunately it made no difference. I modified the 99-serial.rules file, but still, the minute I add a modbus and a debugger (in a fresh clean flows, not other flows what so ever) and deploy. Node-RED immidiately goes into infinate boot-loop :frowning: root@C…

My only trick is to try something different docker container like Telegraf in the repo I linked to then we know if its only Node-RED or not in your setup… Recipe something like: docker pull arm32v7/telegraf You can modify this conf-file, you only need the serial driver app inside here… Wag…
