Practical Tips and Techniques
We will look at numbering systems in our BRX Do-More controller. This will include physical IO, casting, and indirect addressing. The BRX Do-More PLC like all of the PLCs in the Do-More Series use strong data typing. This means that there are fixed memory structures to work within your program. Errors will be displayed if … Read more
We will now use the Do-More Designer software to establish communication with the BRX Do-More PLC. This is the same software that we used in the Learn PLC Programming Fee Video Series. Using the Do-More Designer software, we will communicate via USB, RS485, and Ethernet. These three methods will allow us to communicate to our … Read more
Looking at a stop-start jog circuit in the PLC will help us understand the differences in hard-wiring the circuit and programming. Basic Start Stop Circuit Let’s start with the primary start-stop circuit. Here is what it looks like hard-wired. (Physical switches wired to outputs devices, such as motor contactors and relays.) When the start pushbutton … Read more
