2. Key Selling Points

1. RS-232C Serial Communication Interface Module
   Provides a dedicated RS-232C serial port for connecting the CP1-series PLC to external devices such as HMI terminals, barcode readers, printers, scales, PCs, or legacy equipment—enabling seamless data exchange and system integration.

2. Compact Size & Direct CPU Integration
   Part of the CP1W expansion module series, it connects directly to the CPU unit (e.g., CP1E, CP2E, CP1L, CP1H) via the backplane—no external power or additional mounting space required—ideal for space-constrained control panels.

3. High-Speed Asynchronous Communication
   Supports baud rates up to 38.4 kbps with standard protocols (e.g., Modbus RTU, Omron Host Link, or custom ASCII protocols), ensuring fast and reliable data transfer for real-time monitoring and control applications.

4. Software-Configurable Communication Settings
   Fully configurable via Omron CX-Programmer software—set parameters such as baud rate, data bits, stop bits, parity, and protocol without DIP switches or manual jumpers—reducing setup errors and commissioning time.

5. Supports Multiple Communication Protocols
   Compatible with:

   • Omron Host Link Protocol (for programming, monitoring, and data access)
   • Modbus RTU (Slave mode)
   • Custom ASCII messaging (for integration with third-party devices) This flexibility makes it ideal for diverse automation environments.

6. Robust & Reliable Industrial Design
   Designed for industrial use with EMI/EMC protection, signal filtering, and noise-resistant circuitry, ensuring stable communication even in electrically noisy environments.
