Practical Tips and Techniques
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
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
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
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
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
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
