The Omron CP1H series of programmable logic controllers are capable of having 4096 timers. There are twelve different timing instructions in the PLC. Six binary and six BCD instructions for the set values of the timers separate the six basic instructions. The memory area for timers have separate areas for the Timer PVs (Present values) and the Timer Completion Flags. We will be looking at the timer instructions in the CP1H along with some programming examples. Continue Reading!
The Omron CP1H series of programmable logic controllers has a fixed input and output addressing system. Every PLC has its own way of addressing its inputs and outputs. We will be looking at how the CP1H series of controller addresses its inputs and outputs. Numbering systems used in this controller will also be looked at as well as addressing. Addressing can be direct or indirect. We will look at how this can be accomplished using examples in the CP1H controller. Continue Reading!
The Omron CP1H series of programmable logic controllers is 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 scan will now solve the new or modified logic in the PLC. CX-Programmer can also set or force inputs and outputs in the controller. This is usually used for troubleshooting and testing of the PLC logic. We will use the Start Stop and Jog circuit that we have developed to test the program in the PLC. Forcing and setting the inputs and outputs will demonstrate to us the operation of the logic. Online programming (online editing) will also be done with our CP1H controller. Continue Reading!
The Omron CP1H series of programmable logic controllers is programmed from CX-Programmer. CX-Programmer is part of Omron CX-One Factory Automation Integrated Tool Package. We will now establish communication to our CP1H PLC using CX Programmer. We will be using the USB connection (Built into the CPU) as well as a RS485 connection using the CP1W-CIF11 module. The Start Stop and Jog circuit that we developed last time will be transferred to the PLC unit. We will then verify that the program in the PLC is the same as the program logic in CX Programmer.

The Omron CP1H series of programmable logic controllers is programmed from CX-Programmer. CX-Programmer is part of Omron CX-One Factory Automation Integrated Tool Package. This software package integrates support software for Omron PLC and other components. Traditionally you had to purchase and install individual support software compatible with each unit and then connect to each PLC and component. CX-One FA Integrated Tool Package eliminates this by providing one package for operating and setup of Omron PLC’s, Special I/O units, components, networking start up and monitoring. This improves the efficiency of PLC system start-ups. We will be looking at starting CX-Programmer within the CX-One Software package and starting a new project for our CP1H PLC. Let’s get started.

The Omron CP1 series of programmable logic controllers consist of three different units. CP1E is the cost effective unit, CP1L is the high performing controller that can come with embedded Ethernet and the CP1H is the position control and comprehensive programmable logic controller.
We will be looking a the CP1H for this series, but a majority of the information can be applied to the CP1E and the CP1L controllers as well.
Let’s start by looking at the CP1H hardware.
The CP1 series is designed with the same basic architecture as the CS and CJ Series. The special I/O units and CPU bus units of the CJ series can then be used. Always use CPM1A expansions units and CPM1A expansion I/O units when expanding the I/O capacity. The following diagram indicates the position of the unit with respect to the CJ and CS series.
