Currently, the driver only works for windows. Is there any guideline to get edcon working on ubuntu as well?

Actually it should also work on Linux Systems. It is even running on Raspberry Pi. Do you have more detailed information what's not working?

jb-chossat commented 2 weeks ago

Based on my tests, the package can run for a limited amount of time on Raspberry Pi OS and arch linux. However, there is a bug, probably in the code managing the communication protocol (Modbus or ethernet/ip), that leads to the communication dropping. Anyone doing more than a few seconds of demonstration should assume it is NOT going to work on linux at this moment.

Can you provide the log output when this error occurs? Does setting the modus timeout to 0.0 in the ComModbus constructor change your behavior?

jb-chossat commented 2 weeks ago

Sure. No, ComModbus at 0 does not change anything in my experience. All data files here: The code run, the console output, the wireshark trace Modbus fail.zip

Thanks! I will try to get access to a Linux PC to investigate the issue.
