BRX Do-More PLC Counters

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 Values), and the Counter Completion Flags. The default size of the counter area is CT0 – CT255. This size can change to the amount that we need for our program. Please see BRX Do-More PLC Numbering Systems and Addressing on how to change the memory configuration of the controller. https://accautomation.ca/brx-plc-numbering-systems-and-addressing/ We will be looking at the counter instructions in the BRX PLC along with some programming examples. As a system integrator, this ability can prove very useful to you in the field when commissioning your automation system. When dealing with counters, we need to look at timing charts. The Secret of Using Counters is a good refresher on using timing charts. https://accautomation.ca/the-secret-of-using-counters/ Let’s get started with the BRX Do-More PLC Counters.
