Yokogawa | A2LP131-S00 PROFINET Communication Module

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.
