Practical Tips and Techniques
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
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 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
