Product Introduction
YOKOGAWA ALE111-S50 is an Ethernet communication module designed for the CENTUM CS3000 DCS environment. This AWA card bridges the Field Control Station (FCS) to the upper-level control network, enabling reliable data exchange and remote monitoring.
Built for harsh industrial plant floors, the AWA operates without explosion-proof housing, making it ideal for safe-area control racks. It supports standard Ethernet protocols to maintain seamless integration with Windows-based engineering and operator stations.

Quality Control Process
Communication cards are the backbone of the DCS. Every AWA undergoes rigorous network validation before shipping. We perform a live ping test and verify link integrity at 10/100 Mbps speeds. Data throughput is stress-tested to ensure no packet loss under heavy load. We inspect the backplane edge connectors for oxidation or wear using magnification. Finally, we verify the module boots correctly and reports its hardware ID to the host controller. Units failing handshake tests are immediately quarantined.
Replacement Pitfall Guide
❗ Suffix Code Decoding: The “-S50” suffix is critical. “S” means standard, “5” means non-explosion proof, and “0” means basic type. Swapping this with an “-SE0” (explosion-proof) or “-S51” (ISA G3 option) can cause mounting or configuration mismatches.
❗ Backplane Slot Assignment: This module must be installed in the designated communication slot on the FCS rack. Plugging it into a standard I/O slot will prevent the system from recognizing the network interface. Always check the rack layout diagram first.
❗ Ethernet Cable Integrity: Network timeouts are often blamed on the card when they are actually caused by bad cabling. Use shielded Cat5e/Cat6 cables and verify the shield is properly grounded at the cabinet. Unshielded cables in high-noise environments will cause intermittent packet drops.
❗ IP Address Conflicts: Before installing the new AWA , verify the IP address matches the original unit’s configuration. A duplicate IP on the control network will cause massive communication collisions and potential DCS crashes.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| Direct | Exact match; plug-and-play replacement | ||
| -S51 | Needs Adaptation | S51 includes ISA G3 option; S50 is basic. Verify environmental specs | |
| -SE0 | Not Compatible | SE0 is explosion-proof; S50 is for safe areas only | |
| ALR111-S50 | Not Compatible | ALR111 is RS-232; ALE111 is Ethernet. Do not confuse |
- Network Throughput: Standard 10/100 Mbps Ethernet
