I have modbus network with 15 DC inverters.
The problem is that from time to time i get error and timeout (byModbusError - 163).
Some time i get it from first drive, and other time from second, forth etc. There is no rule.
For each inverter i set:
a. timeout - 5000ms
b. send 2 registers per 400 ms
c. receive 3 registers per 100ms
Baud rate of network 19200,8,1, and 5 ms as delay between frames (in PLC and in DC inverters).
In attachment i am sending my settings one of DC inverters
Do you have any idea where the problem is?
