Delta HMI Omron C Series PLC Connection Manual
Summary
This manual provides comprehensive technical guidelines for the integration of Omron C Series PLCs with various Human-Machine Interfaces (HMIs) and control hardware. It details specific wiring configurations using both RS-232C and RS-422 protocols across multiple DOP series models, ensuring reliable system connectivity. The guide also serves as a crucial reference for memory mapping, defining every register type—including IR, HR, AR, LR, and DM areas—and corresponding address ranges required for accurate programming and robust industrial automation design. This resource is essential for control engineers and technicians implementing Omron PLC-based systems.

Frequently Asked Questions
What is the default communication speed for the controller?
The default communication rate is 9600, 7, Even, 2.
How should I connect an Omron PLC using RS-232 (DOP-A/AE/AS)?
Connect DOP-B to Controller via a 9 pin D-sub and ensure matching wiring for RXD, TXD, GND, etc.
What is the maximum addressable word area in the DM area?
The DM area supports addressing from DM0 up to DM9999.
Which communication protocol uses RS-422 connections when linking DOP-A/AE units?
RS-422 links for DOP-A/AE units require a 9 pin D-SUB male connection for both ends (RXD-, RXD+, TXD-, TXD+).
