Practical Tips and Techniques
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
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
A majority of the programmable logic controller (PLC) programs will include a timer instruction. The BRX Do-More series of programmable logic controllers have several different timers available for your program. There are nine different basic timing instructions in the PLC. The memory area for timers includes the Timer PVs (Present Values) Timer SVs (Set Values) … Read more
We will apply the five steps to PLC program development to a pick and place robot example. The example will use a BRX PLC communicating to Factory IO (3D Software Simulator). 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
We will now look at monitoring and testing our BRX Do-More program in our controller. Our first program for the BRX Do-More PLC involved a start-stop jog circuit. We will now use the Do-More Designer Software to monitor, test, and modify this program. As a system integrator, this ability can prove very useful to you … Read more
We will now look at writing our first program for the BRX Do-More PLC. The Do-More Series allows us to write programs online or offline with the PLC controller. The series will also allow us to do online editing. We can change program information and download the new program between scans of our controller. As … Read more
