Yokogawa A2LP131-S00 PROFINET communication module for CENTUM VP

Seamless Integration of Industrial Ethernet with DCS Architectures

In continuous process and hybrid automation industries, connecting modern field smart instruments and subsystem controllers to a central Distributed Control System (DCS) requires fast, standardized communication protocols. The Yokogawa A2LP131-S00 PROFINET Communication Module acts as an advanced PROFINET IO-Controller within the Yokogawa CENTUM VP platform. Installed directly into Field Control Stations (FCS) or expansion ESB node units, the module establishes high-speed 100 Mbps data exchange with field PROFINET IO-Devices, bringing field-level diagnostic and measurement data into central control function blocks.

Certified Compliance and Robust System Capabilities

The A2LP131-S00 module is officially certified to comply with PROFINET Specification Version 2.35 Conformance Class A (CC-A), while also supporting CC-B and CC-C devices within the CC-A functional scope. Each module features a single IEEE 802.3 100BASE-TX physical interface using a standard RJ-45 connector and 2×2 twisted-pair shielded cabling over segment distances up to 100 meters.

With an I/O communication data capacity of 1000 words per module and support for up to 128 connectable PROFINET IO-Devices, the A2LP131-S00 allows control engineers to map data types—including Boolean, Integer16/32, Unsigned16/32, and Float32—directly into CENTUM VP regulatory and sequence control function blocks.

Alarm Handling, Network Redundancy, and Modular Design

Beyond standard cyclic data transmission, the A2LP131-S00 actively processes alarm messages generated by field IO-Devices and routes notifications instantly to the Field Control Unit (FCU). In high-availability architectures, the module supports PROFINET network communication path dual redundancy when configured with managed switches running Media Redundancy Protocol (MRP) in a ring topology.

Compact and lightweight at approximately 0.31 kg, the module measures 32.8 mm in width, 125.5 mm in depth, and 130 mm in height. It operates on a maximum current consumption of 0.8 A, maintaining low thermal output in control cabinets.
