  1. Hello we have a problem with communication with Modbus slave V570. SCADA (as a master) send request READ HOLDING REGISTERS and READ COILS to slave. Function READ HOLDING REGISTERS works fine. SCADA read registers MI, but function read coils doesn't work. SCADA cannot read registers MB. I checked also the system bits SB305, and it is false.
