7 Best PAC and PLC Controllers for Industrial Machines

Programmable Logic Controller (PLC) and Programmable Automation Controller (PAC) are the most efficient industrial computer devices that are designed and developed to assists manufacturing operations. It is often regarded as the brain of the manufacturing process as they efficiently control automation processes/equipment with high reliability. 

PLC and PAC are similar as both have standard features and functionalities, which have been developed over the years. While PLC has been around for more than four decades, recent advancements in technology have obscured the lines between both controlling pieces of equipment.

Advance Applications Of PAC and PLC

PLC has in-built networks enabling it to communicate between multiple PLCs, I/Os and human-machine interfaces, and SCADA systems (or Supervisory Control And Data Acquisition). In contrast, PAC is incorporated with modular design open architecture use for communicating, monitoring, and controlling equipment covering multiple networks and devices.

While PLC applications are perfect for high-speed and straightforward machine controlling, PACs have ideal applications for large-scale automation projects and operations. It is because they differ in architecture, enabling them for different operations.

Depending upon functionality, programming, memory, process modules, and various other parameters, you can choose PLC and PAC controllers for various applications.
