Configuring Modbus
Modbus Point Mapping
The PowerSmart Socket PQM provides 120 user assignable
registers in the address range of 0 to 119. You can re-map
any register available in the device to any assignable register
so that Modbus registers that reside at different locations
may be simply accessed using a single request by re-
mapping them to adjacent addresses.
Initially these registers are reserved and none of them points
to an actual data register.
To build your own Modbus register map:
1. From the Meter Setup menu select Protocol Setup and
click on the Modbus Registers tab.
2. Click on the Default button to cause the assignable
registers to reference the actual default device register
11776 (0 through 119 are not allowable register
addresses for re-mapping).
