Productivity 2000 Series PLC Online Programming

The Productivity Suite Software allows us to modify our existing program and execute the new code without stopping the scanning of the PLC. This is referred to as online programming or editing. We change the ladder logic code and when we save it to the PLC, the current scan of the PLC is held until … Read more

BRX Do-More PLC High-Speed Input Pulse Catch

BRX Do-More PLC High-Speed Input Pulse Catch

The High-Speed Input Pulse Catch will set an output that can be seen by the PLC ladder logic scan in response to an input pulse. Inputs that are too fast to reliably be seen by the ladder logic scan time will be seen. The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. … Read more
