Product Overview

ALE111‑S51 is Yokogawa FIO‑series Ethernet communication module for CENTUM‑VP DCS. It acts as a gateway between the DCS field‑control‑station and external third‑party automation devices. It supports Modbus‑TCP and multi‑brand PLC communication protocols, reducing custom‑gateway hardware requirements. This module is widely used in petrochemical, power‑generation and oil‑gas plants for cross‑system data integration. Available as refurbished and surplus spare parts for DCS‑system expansion and maintenance work.

Application Notes

‑ Install into designated slot of FIO node‑unit (AFV / ANB series hardware). ‑ Configure IP‑address and communication parameters via CENTUM‑VP engineering tool. ‑ Use 100‑ohm category‑3/5 UTP twisted‑pair cable for 10BASE‑T link. ‑ Typical deployment: petrochemical plant CENTUM‑VP DCS third‑party‑interface spare‑part stocking.
