For example, if the values of Phase A Current (register address 0229H) and RTD 1 Celsius Temper-
ature (register address 0240H) are required to be read from a 239, their addresses may be
remapped as follows:
1. Write 0229H to address 0180H (User Definable Index 0000) using function code 06 or 16.
2. Write 0240H to address 0181H (User Definable Index 0001) using function code 06 or 16.
A read (function code 03 or 04) of registers 0100H (User Definable Register 0000) and 0101H (User
Definable Register 0001) will return the Phase A Current and RTD 1 Celsius Temperature.
