Configuring Modbus
Modbus Point Mapping
The EM13X Series 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:
Select Protocol Setup from the Meter Setup menu, and click on the
Modbus Registers tab.
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 5-21 : Protocol Setup Dialog Box – MODBUS Registers Tab
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.
Click Send to download your setup to the meter.
