Whether it’s a PLC, a PAC or a PC, a controller is a fundamental piece of hardware required for an automated system to function. Controllers have been around for decades, and have faced great technological automation. Specifying controllers for a particular application has gained increased amount of complexity due to the many options available. Quality, cost, ease of use, functionality, etc. are just some of the factors that have to be taken into account before specifying a PLC.
Be True to the Requirements
Every project has its own specific requirements. When working with a controller, it’s important to know its functionalities and limitations. There’s nothing worse than selecting a particular device and then uncovering its pitfalls halfway in the project. Before you commit to a controller, its best to bench test the process.
