User Defined Modbus Map
It is possible to map the controller’s fixed Modbus registers to a set of Modbus D-registers from 1200 – 1219. These
user defined registers can be any Modbus registers from the set of tables above.
The user defined Modbus map is assigned using D-registers 721 – 740 (addresses 40722 – 40741). To create the
user defined Modbus map, write the D-register number of the desired parameters to D-register 721 (address 40722).
That parameter’s value will be available in Modbus D-register 1200 (address 41201).
For example, to configure a custom Modbus map of D-register 1200 to D-register 0 for NPV, D-register 1201 to
D-register 1 for NSV, D-register 1202 to D-register 5 for MVOUT, D-register 1203 to D-register 207 for AT, D-register
1204 to D-register 210 for 1.P, D-register 1205 to D-register 211 for 1.C, and D-register 1206 to D-register 212 for
1.D, set the user defined Modbus map as shown below.
