I've found the following problem:

  • set up uc in eva ics 3.2.0 as modbus slave on serial port
  • send a garbage to the port
  • controller modbus slave stops responding until restarted

I was able to reproduce this issue, yes, unfortunately it's a bug of pymodbus library. It seems to be fixed in 2.2.0 however since 2.2.0 isn't released yet, the only way is to build it from sources:

https://github.com/riptideio/pymodbus/releases/tag/v2.2.0rc4

we'll set pymodbus 2.2.0 in install requirements as soon as it will be released.
