2024 State of Technology Report: PLCs & PACs

June 24, 2024

Programmable logic controllers (PLCs) have been a popular method of machine control since the PLC was invented in the late 1960s as a replacement for relay logic. The similarly utilized programmable automation controller (PAC), which evolved more than 20 years ago, combines the abilities of DCS, RTUs and PC-based control. Keeping up with advancements can be daunting.
This new State of Technology Report from the editors of Control Design:

  • defines the PLC
  • explains how programming languages have evolved
  • differentiates PLCs from PC-based control
  • investigates how packaging equipment is controlled
  • looks into PLC programming for vision systems.
