The above shows you one nested FOR NEXT loop. (Repeat 3 times)ДЇOR NEXT loops can be nested up to 15 levels. This means that our FOR NEXT loop will activate for one scan. If DM is equal to or greater than 3 the break will be activated. In our example, we are using a comparison to control the BREAK instruction. We could also use the JUMP and JUMP END instructions to exit out of this loop. We use the BREAK instruction to exit the FOR NEXT loop without finishing. The instructions between the FOR and NEXT are repeated for a specific number of times. The following chart will explain the differences between the instruction.ДЇOR-NEXT LOOPS: FOR(512)/NEXT(513) вЂ“ Omron CP1H MULTIPLE JUMP and JUMP END: JMP0(515) and JME0(516) The CP1H also offers other jump and jump end instructions. The instructions between the jump and jump end are not executed so the previous status of the outputs is maintained. If the condition is off then the program jumps directly to the first jump end instruction with the same number. When the execution condition is on, no jump is made and the program is executed normally. JUMP and JUMP END: JMP(004) and JME(005) вЂ“ Omron CP1H You can see that MILH 1 is nested within MILH 0. (MILH(517), MILR(518), and MILC(519)) Unlike the standard interlocks, these instructions can be nested together. The Omron CP1H also has multi-interlock differentiation hold, multi-interlock differentiation release and multi-interlock clear instructions. This will allow you to section off your program in blocks depending on the execution condition. You can have more than one interlock instruction for an interlock clear. If 21.00 is off the output of 100.00 is also off. When 21.00 (execution condition) is turned on the program functions as expected and turns on the output 100.00. In our example, we are using an always-on flag to turn on the first output between the two instructions. The following table shows various outputs and the way in which the interlock function will be executed. (Reset / Off) If the execution condition is on then the program executes normally.

When the execution condition is off, all of the outputs between the interlock and interlock clear are interlocked. INTERLOCK and INTERLOCK CLEAR: IL(002) and ILC(003) вЂ“ Omron CP1H (CX-Programmer вЂ“ View Mnemonics (Alt +M)) You will see this instruction past the END statement in your program. It is sometimes used as a place holder when programming in the mnemonic. The instruction has no function when scanned in the program. This automatically happens when you start a new project with CX-programmer. At least one END instruction must be present in your program in order to indicate the end of the program. It can also be used in interrupt tasks to indicate the end of the task. This instruction indicates the end of the program. The first few program control instructions are basic for all Omron programs. Sequence Control Instruction вЂ“ 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. LetвЂ™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 вЂ“ 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.
