This section covers the RS485 Modbus Registers and Proprietary CAN Parameter Map.
MPC-20-R2 RS485 Modbus Registers
NOTE: The registers labeled Read/Write will allow the operator to change values through the
Modbus as a temporary modification. If power is cycled to the MPC-20-R2, the values changed
via Modbus will revert back to the last value entered locally at the MPC-20-R2 unless saved
using Register 40240. Writing a 1 to register 40240 will allow saving register changes to the
controller.
