Practical Tips and Techniques
Automation Direct BRX Series PLC. This is part of the Do-More family of controllers.
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 online editing and the powerful debug mode of our BRX Do-More 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 modify this program while the PLC is scanning the logic. This is referred to as online … 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
We will now use Modbus RTU to connect a Click Master to a BRX Do-More Slave controller. Recently I was asked to demonstrate communication between a Click PLC and BRX Do-More PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many … Read more
