I can control 2 devices via Modbus RTU communication with each device connect to 1 X20CS1030, so I use 2 CS1030, when I try to give same command at the same time via 1 variable, my devices not moving at the same time, there is a little delay from 1 device to the other one, how can I synchronize move 2 devices with Modbus RTU 485?
Hello,
neither Modbus nor RS485 are synchronous. Therefor you will always have a delay in between two devices as especially RS485 is not able to send 2 frames “in parallel”
best regards
