ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
Almost every PLC program includes a timer instruction. The Productivity Mini PLC P1-M622-16DR (P1 Mini) offers several timer instructions. (P1 Timer) We discussed the Timed Coil (TMC) and Flasher Coil (FLS) in our last post as part of our discussion of contacts and coils. In this session, we will review the instructions for the Simple … Read more
Master the Clock: Orchestrating Automation with Click PLC Timers. The hum of the conveyor belt was off. Not entirely stopped, but hesitant. Mark, a veteran automation engineer, frowned as his eyes scanned the control panel of the small packaging plant. “Another bottleneck,” he muttered, running a hand through his already disheveled hair. The current system, … Read more
Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs. This visual … Read more
The High-Speed discrete inputs can be configured to measure the amount of time between pulses. When you want a scaled value representing a speed or rate, the high-speed input timer is a better option for pulse rates below 5 kHz. This is compared to using the high-speed input pulse counting selection. The BRX Do-More series … Read more
