Yokogawa ALE111-S53 S1 | Ethernet Communication Module

The Yokogawa ALE111-S53 S1 is a high-performance Ethernet communication module designed for the Centum VP and Centum CS 3000 Distributed Control Systems (DCS). This module enables the Field Control Station (FCS) to communicate with external subsystems—such as PLCs, gas chromatographs, and power monitors—via Ethernet using various protocols. The “S53” designation indicates a standard type with support for dual-redundancy, while the “S1” suffix denotes the specific hardware style and revision for modern system compatibility.

Product Instructions for Use

  1. Redundancy Setup: For high-availability applications, install two ALE111 modules in adjacent slots of the AFV or ANB unit. Configure them as a redundant pair in the system software to ensure bumpless communication failover.

  2. Cable Installation: Use high-quality shielded twisted-pair (STP) or unshielded twisted-pair (UTP) Category 5e cables. Ensure the cable is securely latched into the RJ45 port on the module’s faceplate.

  3. Software Configuration: Use the Yokogawa System View (Engineering Station) to define the IP address, subnet mask, and communication port for the module. Define the scan rate and data mapping for the target subsystem devices.

  4. Diagnostics: Monitor the front-panel LEDs. The “RDY” LED should be solid green. Flashing “TX” and “RX” LEDs indicate active data transmission and reception.

Q&A: Frequently Asked Questions

Q1: Does this module support 100Mbps or 1Gbps speeds? A1: No, the ALE111 is a 10BASE-T module designed for 10 Mbps. While this is slower than modern PC networking, it is highly stable and more than sufficient for industrial process data exchange.

Q2: Can I use this module to connect the FCS to the HIS (Human Interface Station)? A2: No. The ALE111 is intended for Subsystem Communication (FCS to external devices). Communication between the FCS and HIS is handled by the Vnet/IP or V net control network modules (e.g., VI702).

Q3: Is the ATK4A terminal block required for this module? A3: No, the ALE111 utilizes a standard RJ45 Ethernet port for connection, so it does not require a traditional screw-terminal block for its primary communication link.
