Practical Tips and Techniques
This offers ways in which you can learn PLC programming.
We will now look at another way of programming our palletizer using the PLC. How many ways can you program the PLC for the same function? The answer is a lot of different ways. You can have ten different programmers working on the same program and get ten different automatic control PLC programs. Sure they … Read more
I have recently come across a free virtual plc simulator called PLC Fiddle. It will enable you to create simple PLC ladder logic code within your browser free. This is an ideal way in understanding PLC concepts for industrial automation. All of the basic PLC instructions that come with most plc units have been incorporated … Read more
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
We will now look at program control in the BRX Do-More controller. The program control instructions will allow us to specify what parts of the logic get solved and when this happens. This will control how the PLC will scan and solve your logic in your program using a synchronous PLC Scan. Understanding the PLC … Read more
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
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
