BRX Do-More PLC High-Speed Input Counter
The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. These inputs can function in Counter, Timer, or Pulse Catch modes. Every CPU will have either 6 or 10 high-speed inputs (HSI) available depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input counts per second that can be coming from devices connected to your PLC like an encoder. Due to the speed of the inputs, they function on the BRX Do-More PLC asynchronous with the PLC scan time.
We will be looking at the wiring of an incremental encoder to our BRX Do-More PLC. The A, B, and Z phases will be connected. Using the high-speed input menus in the Do-More Designer programming software we will specify the counter mode of operation. We will also scale the input so we can determine the revolutions per minute (RPM) rate. This will be monitored on our data view window. Let’s get started with the BRX Do-More PLC High-Speed Input Counter.

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 their communication capabilities.
