BRX Do-More Modbus Addresses All Modbus Read and Write requests from external devices will be serviced from the four built-in memory blocks for use by the Do-more controller's Modbus Server (Slave) device. MC (Modbus Coils), MI (Modbus Inputs), MHR (Modbus Holding Registers), and MIR (Modbus Input Registers) The Modbus Server only has access to the MI, MC, MIR, and MHR memory blocks in the controller, it cannot access the other (native) memory blocks or the I/O in the controller directly.
