Product Description
The ALR111 is a high-performance serial communication interface module for the Yokogawa FIO system. It enables reliable data exchange between the CENTUM VP Field Control Station (FCS) and third-party subsystems such as PLCs, gas chromatographs, and power monitoring equipment.
The ALR111 (Model: ALR111) supports RS-232C asynchronous communication, making it an essential bridge for integrating diverse industrial intelligence into a centralized DCS environment.

System Integration and Redundancy
-
Supports dual-redundant configuration when installed in adjacent node slots, maintaining serial communication during module failure.
-
Acts as a gateway to non-Vnet/IP devices, centralizing third-party field hardware management via the standard operator interface.
Frequently Asked Questions
What protocols are natively supported by the ALR111?
-
Primarily Modbus RTU/ASCII with third-party PLCs.
-
Supports “no-protocol” mode for custom C-language scripts to handle unique instrument data.
Can the ALR111 be used for RS-485 communication?
-
No. The ALR111 is strictly RS-232C. Use the ALR121 module for RS-422/RS-485 requirements, which provides longer distances and electrical compatibility.
