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 be using the USB connection (Built into the CPU) as well as an 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 are programmed from CX-Programmer. CX-Programmer is part of the 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 PLCs, Special I/O units, components, networking start-up, and monitoring. This improves the efficiency of the 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. Continue Reading!
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.
We will be looking a the Omron 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 Omron 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 expansion 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 hardware.

Microsoft SQL Server Express 2014 is a free, edition of SQL Server this is ideal for learning and developing desktop, web, and small server applications. The database size can be 10 gigabytes in size. SQL Server Express 2014 release includes the full version of SQL Server 2014 Management Studio. This is a method to read, write and maintain our database. (Tools) We will be installing this SQL Server database so we can connect to it for data acquisition (data logging) from our PLC applications.
Installing the software – SQL Express
Download the software
The download file can be obtained from the website for SQL Express 2014.
We will be installing the ExpressAdv 64Bit\SQLEXPRADV_x64_ENU.exe on a windows 7 64 bit machine.
This is the latest software that can be installed on the Windows 7 operating system. Continue Reading!
