How to interface PLCs with 6 digit modbus addresses in Ignition SCADA?
I am not able to get the Data in Ignition SCADA with modbus address 40XXXX address. With same PLC, I could able to get the datas in SCADA with ‘Wonderware/Vijeo Citect’ software.


Take a look at this portion of the manual.

Usually the 1/2/3/4 prefix is just indicating the area. 4xxxxx is Holding Registers.
