BRX Do-More PLC to Modbus Remote IO Controller BX-MBIO

The BRX Do-More PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol. Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.
We will connect the BRX Do-More PLC to the Modbus remote IO. This will be done using the Modbus TCP and Modbus RTU protocol. Ethernet and serial RS485 communication to the BX-MBIO unit will be the media. Let's get started.

There are several reasons why we are using the BRX Series 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

The BRX series of programmable logic controllers consist of four different units. They differ depending on the Inputs and Outputs built into the unit and if it has the ethernet port.
No I/O Micro PLC unit – (BX ME)
10 Point Micro PLC unit – (BX 10/10E)
18 Point Micro PLC unit - (BX 18/18E)
36 Point Micro PLC unit - (BX 36/36E)
These CPUs (Central Processing Units) are also known as MPU (Multi-Processing Units) because of the communication capabilities.
