    RLPC MODBUS Register Map v1.44 Data Units Registers The 42xxx register series identifies the units used by data items in the 30xxx series. These registers run in parallel with the Data Registers. For example, Data Register 30010’s Units Register is 42010. Note: Units are stored as 4 character ASCII strings across 2 registers.
