i have a Modbus RTU system with MicroLogix 1400 as master and 3 Eurotherm instruments (2404, 2704)+ Allen Bradley drives as slaves (total 7). Facing problem of communication going too slow if one or more slaves are switched off or goes fault. sometimes communication stops also. in normal case when all are healthy then communication is very good.
used channel 0 and NC01 cable.
