We will connect Node-RED to the Omron CP1H PLC. Node-RED has the ability to read and write to the Omron controller using special protocol commands.

Other protocols will allow you to collect and log information from the programmable logic controller. These methods of communication will allow you to program the controller.
#Omron plc serial communication protocol series#
High speed communications with NT/NS series message displays and touch screens using plug and play connection to the peripheral port or an RS 232C port is offered direct by Omron. This advance serial communication feature incorporates a separate co processor that allows a programmer to customize the string of serial communication that will communicate with any serial devices virtually. RS 485 and RS 422 communication ports can be implemented into your controller system for an easily configured multi drop serial network. The communication adapters can convert the peripheral port to use the RS 232C. To connect your personal computer for programming the controller can be used RS 232 port. Multiple ports are available for simultaneous communication to barcode readers, modems, HMIs, handheld programmers and other devices. The Omron models offer RS-232C communications, some with built in ports, others use an adapter. Most Omron controllers are accessible via a single programming cable, eliminating the need for multiple cables to support the installation. Many models have built in communication ports or can be upgraded via adapters or inner boards, enabling communications with Omron’s larger PLCs in an environment of distributed control. Communications between micro and small controllers and networks or other devices has never been easier.
