Omron CP1H PLC PLC Basics

Omron CP1H PLC Compare Instructions

We will now look at the compare instructions available on the Omron CP1H controller. Just about every program usually has some data comparison instruction. This is the ability to compare information from one area of the controller to another and act on results. The Omron CP1H series of programmable logic controllers provide several different ways to compare the information. We will be looking at several different ways in which we can do this with some programming examples. Sometimes the instruction used for data comparison in the Omron CP1H will determine the kind of data that we are comparing. You must look at the individual instructions to determine if this is the case or not.
