Modbus Settings - Default Data Mapping
The default mapping is noted below.
-
Only Direct Address Tags can be used in the Modbus Settings fields. (No user defined variable tags can be used.)
-
We recommended using the M and W Memory types.
-
The default mapping uses the physical input (%IX) and output(%QX) addresses in the Bit read/write areas. These addresses will allow control of actual PLC I/O remotely.
