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.
