BRX Do-More PLC Modbus RTU to Solo Controller

We will now look at using serial Modbus RTU to communicate with a Solo process temperature controller using our BRX Do-More Controller. Serial communication instructions will allow you to send and receive serial data to an external device. The communication method that you set up can be ASCII or numeric (binary). ASCII (American Standard Code … Read more

BRX Do-More PLC Drum Instruction Sequence

We will now look at the drum instruction in our BRX Do-More Controller. Drum instructions are great tools when you have a simple sequence of events that need to occur at a set time interval or as a result of an event. They mimic an electromagnetic drum sequencer. The BRX Series PLC has a drum … Read more

BRX Do-More PLC Shifting Instructions

We will now look at shifting instructions in the BRX Do-More controller. PLC shifting instructions will move bits in memory areas a fixed amount when instructed. Bits are on/off, 1 or 0, and are usually associated together to form a memory location. The memory location can be used for numbers or positions. PLC BITS NUMBERS … Read more

BRX Do-More PLC Math Instructions

Math instructions are used to perform mathematical calculations. The BRX Do-More PLC has math instructions that can be used in a wide variety of applications. We will be looking at the INC increment, DEC decrement, LERP linear Interpolation, RANDSEED Random Number Seed, and the MATH Calculated Expression instructions. The automation system that you implement may … Read more

BRX Do-More PLC Compare Instructions

Compare instruction is often used in PLC programs to test pairs of values. The output of this comparison conditions the logical continuity of a rung. The BRX Do-More series of programmable logic controllers have the following compare contact instructions. = (if Equal contact) <> (if Not Equal contact) > (if Greater Than contact) >= (if … Read more

Modbus RTU BRX Do-More Master to Click Slave PLC

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 … Read more

BRX Do-More PLC High Speed IO (Input / Output)

The BRX Do-More series of programmable logic controllers has built in high speed inputs and outputs. 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 … Read more

BRX Do-More PLC Counters Explained

A majority of the programmable logic controller (PLC) programs will include a counter instruction. The BRX Do-More series of programmable logic controllers have several different counters available for your program. There are five different basic counter instructions in the PLC. The memory area for counters (CT) includes the Counter PVs (Present Values) Counter SVs (Set … Read more
