PLCs & PACs: Is One Better Than the Other?

Programmable Logic Controllers (PLCs) and Programmable Automation Controllers (PACs) have a lot of similarities in how they are used in manufacturing automation. They each provide the programming logic behind controlling processes to boost productivity and they both are highly reliable.

Here at OSCO, we determine what is best to use based on the application and its complexities, and future capabilities that maybe needed.


We often recommend PACs if the application requires more high-level functionality and future expansion. Through various communication protocols, the PAC can monitor, control, and manage data across multiple systems. PACs can monitor and control a great deal of input and outputs, and because of its open architecture, adding or removing components is a simple change.


PLCs are intended for simpler processes and smaller automation projects that don’t require advance functionality or complicated programming. They are useful for basic control processes that won’t have the need for expandability. Advanced PLCs are capable of high-speed I/O and can be set up to communicate between other systems, but at this point, we would recommend going with a PAC. PLCs are more cost-effective when budget constraints are a factor.
