BRX Do-More Simple Modbus Serial Communication

The newest version of the Do-More Designer Programming Software (2.9) includes a Modbus I/O Scanner. This will simplify Modbus RTU serial communications to any device. Communications are done independent of the PLC scan time and will have little or no ladder logic for the program. We will be communicating to a Solo process temperature controller via Modbus RTU RS485. (twisted pair) Setting up the Modbus IO scanner, and reading the present value (PV) and set value (SV) of the Solo. We will also write the set value (SV) located within the BRX Do-More controller. This will all be done without using any ladder logic code. Let’s get started. More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/brx-do-more-...

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 their communication capabilities. https://www.accautomation.ca
