This will trigger the instruction to happen only once. MCMP(019) when used will be scanned and executed every cycle of the PLC that the input condition is when used will be executed when the input condition turns from off to on.
Several of the instructions can have different variations. Links are provided at the end of this post.
A full explanation can be obtained by using the help menu in the CX-Programmer software or the Programming Manual for the CP1H. We will be covering several different data comparison instructions. Setting, Forcing and Online Editing – Video Previously in this CP1H series, we have discussed: You must look at the individual instructions to determine if this is the case or not. Sometimes the instruction used for data comparison in the Omron CP1H will determine the kind of data that we are comparing. We will be looking at several different ways in which we can do this with some programming examples. The Omron CP1H series of programmable logic controllers provide several different ways to compare the information. This is the ability to compare information from one area of the controller to another and act on results. Just about every program usually has some data comparison instruction. We will now look at the compare instructions available on the Omron CP1H controller.
