ALE111-S01 CENTUM VP Ethernet Communication Module | Yokogawa

Product Overview

The Yokogawa ALE111-S01 functions as a high-performance communication gateway within the CENTUM VP and CS 3000 Distributed Control System (DCS) architectures. This module establishes a robust Ethernet link between the Field Control Station (FCS) and external subsystems, including PLCs, smart instruments, and laboratory management systems. By facilitating real-time data polling and command transmission, the ALE111-S01 centralizes plant-wide information into a single operational interface. We supply this unit as 100% Brand New and Original, ensuring full compliance with factory safety and network protocols.

Part Number Breakdown

The ALE111-S01 utilizes a specific alphanumeric suffix to define its hardware grade and functional parameters:

Technical Specifications

This module integrates directly into the FCS backplane to provide high-speed industrial networking.

• Protocol Support: Supports Modbus/TCP and standard TCP/IP communication layers.

• Data Transfer Rate: 10/100 Mbps (Full/Half Duplex).

• Mounting: Plugs into the Field Control Station (FCS) I/O module slot.

• Redundancy: Supports dual-redundant configuration for mission-critical paths.

• Isolation: Galvanic isolation protects internal DCS circuitry from network-borne surges.

• Condition: Guaranteed 100% Brand New and original factory sealed.

Engineering Advantages

The ALE111-S01 addresses critical integration hurdles in modern process plants:

• Seamless Subsystem Integration: Engineers often face "data silos" when connecting third-party PLCs to a Yokogawa DCS. The ALE111-S01 eliminates this barrier by providing a standardized Ethernet gateway, allowing the DCS to read and write variables directly to external controllers.

• Deterministic Network Performance: Unlike commercial-grade switches, the ALE111-S01 manages communication traffic within the DCS environment to ensure that process data packets maintain priority. This prevents network latency from affecting critical control loops.

• Hardened Industrial Design: High-voltage transients in motor control centers often damage standard network cards. The ALE111-S01 features industrial-grade shielding and noise rejection, maintaining stable communication in environments with severe electromagnetic interference (EMI).

• Rapid Hardware Deployment: The "Plug-and-Play" architecture allows for quick installation into existing FCS racks. The module integrates with the CENTUM software suite for streamlined IP addressing and tag mapping, significantly reducing commissioning man-hours.

FAQs

• Does the ALE111-S01 support dual-redundant network paths?

  Yes. You can install two ALE111-S01 modules in a duplexed configuration. If the primary module or network cable fails, the standby unit assumes communication tasks instantly to prevent process data loss.

• What is the difference between the S01 and S00 versions?

  The S01 designation typically identifies specific internal revision levels or basic type functionality as defined by Yokogawa's current manufacturing standards. Both follow the "Standard" hardware path, but you should verify your software revision for exact driver compatibility.

• Can I use this module to connect to an external OPC server?

  The ALE111-S01 provides the hardware layer for Ethernet connectivity. While the module handles the physical data transfer, your CENTUM software must include the appropriate communication drivers (such as Modbus/TCP or OPC) to interpret the data.

• Is this a refurbished or "pulled" unit?

  No. We sell only 100% Brand New ALE111-S01 modules. Every unit arrives in its original factory packaging with intact seals and a full 12-month warranty.
