![]() The first few program control instructions are basic for all Omron programs. Sequence Control Instruction – Omron CP1H This will give you a general idea of the instructions available. We will now go over some of the program control instructions in the Omron CP1H. Please refer to the programming manual or help file in CX-Programmer for different variations of the instructions that you want to use. This will trigger the instruction to happen only once. SBS(091) 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. Let’s look at when this instruction will execute: 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. Several different program control instructions are available in the CP1H. Setting, Forcing and Online Editing – Video Previously in this CP1H series, we have discussed: Examples of some of the instructions will be presented. We will be looking at some of these instructions in the Omron CP1H PLC. Interlocks, Jumps, For Next Loops, Subroutines and Step instructions are some of the ways in which we can control our program in the PLC. Understanding the PLC program scan will explain the synchronous and asynchronous program scanning. These are just a few ways in which the controller will execute your logic using a synchronous PLC scan. Sequence control, Subroutines, and Step instructions can be used. ![]() The Omron CP1H programmable logic controller has several different ways to control the program and the way in which your program executes. ![]()
