Omron CP1H Data Conversion Instructions

We will now look at data conversion instructions in the Omron Cp1H Controller. Programmable logic controller programming is all about manipulating the bits within the memory of the controller. Sometimes we need to convert from one form to another. This is where we will use data conversion instructions. BCD to Binary, Line to Column, Grey … Read more

Omron CP1H Data Shifting Instructions

We will now look at data shifting instructions in the Omron CP1H controller. PLC programming is all about how we can manipulate the information stored in the PLC. We have already looked at timers, counters, moves, and comparison instructions. Data shifting is a different concept that will move bits and words around in memory. This … Read more

Create an Analog Voltage Input Tester for a PLC

Create an Analog Voltage Input Tester for a PLC

We will create a simple and inexpensive analog voltage tester for a PLC using a potentiometer and a 9VDC battery. The potentiometer will be 5K ohms. This should be enough impedance for most analog inputs of the programmable logic controller. (PLC) Voltage impedance for analog voltage inputs is in the megaohm range where the current … Read more

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 … Read more

Omron CP1H PLC Data Movement Instructions

Every program usually has some kind of data movement. This is the ability to transfer information from one area of the controller to another. The Omron CP1H series of programmable logic controllers provide several different ways to manipulate this information. We will be looking at several different ways in which data movement can happen with … Read more

Omron CP1H Setting, Forcing and Online Editing

We will now look at online editing, setting, and forcing that can be done on the Omron CP1H controller.  The Omron CP1H series of programmable logic controllers are capable of online programming. This is when the PLC is solving logic and at the end of the scan, programming logic is added or modified. The next … Read more

Omron CP1H Establish Communication

We will now establish Omron CP1H communication using the built-in USB connection. CX-Programmer will be used to communicate. The Omron CP1H series of programmable logic controllers are programmed from CX-Programmer. CX-Programmer is part of the Omron CX-One Factory Automation Integrated Tool Package. We will now establish communication with our CP1H PLC using CX-Programmer. We will … Read more

Omron CP1H PLC System Hardware – CP1 Series

Omron PLC - CP1H Series (CP1 Omron PLC Family)

We will now look at the system hardware of the Omron CP1H controller. The Omron CP1 series of programmable logic controllers consists of three different units. CP1E is the cost-effective unit, CP1L is the high-performing controller that can come with embedded Ethernet and the Omron CP1H is the position control and comprehensive programmable logic controller. … Read more

How to Troubleshoot a PLC – Ladder Logic

We will look at how to troubleshoot a plc racing condition. Two examples are explained in racing conditions in the PLC. The PLC will update only at the end of the program logic. Items set will not happen until the I/O is refreshed. How to trigger events when you want them is discussed. Your control … Read more
