Yokogawa ALP111 Communication Module

Product Introduction

The Yokogawa ALP111 Communication Module is a high-performance communication interface designed to connect control systems to remote I/O networks via PROFIBUS-DP. It acts as a key communication bridge in distributed control environments, enabling seamless and deterministic data transfer between Yokogawa’s CENTUM VP or CENTUM CS 3000 systems and field devices that support the PROFIBUS-DP protocol.

The ALP111 enhances automation flexibility by integrating third-party field instruments, valves, actuators, and sensors into the centralized control environment. It is especially valuable in large-scale plants requiring interoperability, reduced wiring complexity, real-time control, and efficient maintenance strategies. As part of Yokogawa’s Field Control Station (FCS) communication architecture, it ensures high availability, diagnostics visibility, and excellent performance in mission-critical industrial applications.

Technical Specifications

Applications

The ALP111 is widely applied across various industries that rely on PROFIBUS-DP for field communication. Common applications include:

• Oil & Gas
  Integration of PROFIBUS-compatible valve positioners and flow meters into the central DCS for precise process control.

• Chemical & Petrochemical
  Interfacing multiple intelligent field devices in hazardous zones with full diagnostics and control access.

• Power Generation
  Communication with field I/O, sensors, and actuator networks for turbine and boiler management.

• Pharmaceuticals
  Enabling validated and traceable communications between DCS and manufacturing field equipment.

• Food & Beverage
  Ensures fast, consistent, and synchronized control across production lines with PROFIBUS-DP compatibility.

• Water Treatment Plants
  Offers seamless remote communication with distributed valve actuators and monitoring devices.

Key Advantages
