Modbus Point Mapping

The PM130 PLUS provides 120 user assignable registers at addresses 0 to
119. You can re-map any register available in the meter to any assignable
register so that registers found at different locations may be accessed with
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 Modbus register map:

1. Select Protocol Setup from the Meter

Setup menu, and click on the Modbus
Registers
tab.

2. Click on the Default button to cause the assignable registers

to reference the actual default meter register 6656 (0 through
119 are not allowable register addresses for re-mapping).

Figure ‎5-20: Protocol Setup Dialog Box – Modbus Registers Tab

3. Type in the actual addresses you want to read from or write to

via the assignable registers. Refer to the PM130 PLUS Modbus
Reference Guide for a list of the available registers. Note that
32-bit Modbus registers should always start at an even register
address.

4. Click Send to download your setup to the meter.
