BRX Do-More PLC Modbus RTU to Solo Controller

by

We will now look at using serial Modbus RTU to communicate to 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 setup can be ASCII or numeric (binary). ASCII (American Standard Communication for … Read more

BRX Do-More PLC Drum Instruction Sequence

by

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

by

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

PLC Programming Example – Palletizer

by

We will apply the five steps to PLC program development to a palletizer example. Our example will allow you to determine how many layers of boxes you want on each skid. Developing the PLC program is a process that can be clearly defined. In our series on the five steps to PLC program development, we … Read more

BRX Do-More PLC Math Instructions

by

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

by

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
