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.
The PLC program must act in this function if required.
When using the BRX Do-More Modbus Client (Master) instructions all of the native and Modbus areas can be used.
See Memory Configuration (Topic: DMD0251) Help File Version: 2.8.3.19 in the Do-More Designer Software for more information.

There are also system configuration tools that will calculate the power budget, I/O count, and price.

There are several reasons why we are using the BRX Do-More Controller. Here are just a few.
– Standalone PLC with built-in I/O
– Built-in Data Logging
– Communication ability – Ethernet Port, RS232, RS485, USB – support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet)
– Built-in Analog input and output
– Integrated motion control
– High-speed counters
– Powerful instruction set (Video of Instructions in software)
– Ability to expand the system with a variety of modules
– Part of the Do-More series of PLCs which use the same free software. (Do-More Designer)
– Integrated simulator in the software capable of external communications for testing
