Product Description

Overview

The ALR111-S00 is a dual-port Serial Communication Module (RS-232C) engineered for Yokogawa CENTUM VP and CENTUM CS 3000 Field Control Stations (FCS). It provides reliable, high-speed connectivity between the DCS and external equipment, including PLCs, analytical instruments, and monitoring devices.

Key Features

Dual-Port Operation

  • Two independent RS-232C ports allow simultaneous communication with multiple devices.

  • Supports baud rates from 300 bps to 115.2 kbps, ensuring timely data exchange for critical process monitoring.

Flexible Protocol Support

  • Native Modbus RTU/ASCII support for standardized industrial communication.

  • “No-Protocol” mode enables customized data frames for proprietary devices.

High Reliability and Redundancy

  • Supports dual redundant configuration for seamless failover between primary and backup modules.

  • Built-in error detection handles parity, framing, and overrun issues to maintain data integrity.

Seamless Integration with CENTUM VP

  • Communication registers map directly to FCS functional blocks for easy monitoring on the Human Interface Station (HIS).

  • Hot-swappable design allows module replacement without disrupting system operation.

FAQ

Q: Can I extend communication beyond 15 meters?
A: Yes, use an RS-232 to RS-422/485 or fiber-optic converter to maintain signal integrity over longer distances.

Q: Can this module operate while the FCS is online?
A: Yes, ALR111-S00 supports hot-swapping without interrupting the control system.

Q: How many modules can be installed in one FCS?
A: Depending on the FCS type, up to 8 or 16 module pairs are supported.
