Modbus Error Log
#2
It means that there are some minor issues with the RS485 communication.
Some things to consider:
1. Connect GND between all Modbus devices (read this: https://store.chipkin.com/articles/rs485...wire-rs485)
2. Install 120 ohm terminator resistor on both ends of the RS485 bus
3. Topology: daisy-chain connection is recommended. Short stubs are OK as well, never use star topology
4. Try using a lower baud rate if devices allow this
