in a project we should control 24 AC drive(VFD-B), 12 drives connect to one SE plc via modbus serial and other 12 drives connect to another SE plc via modbus serial and 2 SE plc's connect to one SA2 plc+Ethernet module via Data exchange which configured in Delta DCI-SOFT software, the registers and coils collect in master plc(SA2) and i can visit them in plc master(SA2) in WPL-SOFT(online mode) but we have a SCADA software from Schneider company clear SCADA and when we set scanners to tag collected data in clear SCADA for 6 drive every thing is normal but when we set more scanners,scanner stat change to offline we set 3 scanners for each drive and we have only 10 registers and 16 coil for each drive,my question is the problem is for master plc( DELTA DVP-SA2) or from SCADA?
