Recently I was asked to demonstrate communication between a BRX PLC and Click PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. It works on a Master / Slave configuration. You can have only one master per network on Modbus RTU (Remote Terminal Unit). A maximum of 32 devices (Nodes) on the network can communicate to the master. A review of the Modbus RTU protocol (RTU frames) can be seen at the following URL. www.rtaautomation.com/technologies/modbus-rtu/ Using the BRX PLC as a Master, we will be communicating to the Click PLC (Slave). Our example will read 10 registers from the Click PLC and write 10 registers from the BRX PLC. Let's get started! More information can be obtained at our website. This includes all of the links mentioned in this video. accautomation.ca/modbus-rtu-brx-plc-master-to-clic… 00:00 Modbus RTU BRX Do-More Master to Click Slave PLC 00:24 Overview of Communication - Modbus 01:40 Modbus RTU (RS485) Wiring 02:16 Click PLC Setup and Program for Modbus RTU Slave Unit 03:21 BRX Do-More PLC Setup and Program for Modbus RTU Master Unit 07:45 Running the programs and testing communication This post is part of our BRX Series PLC.

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 an 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. www.accautomation.ca/
