Product Overview

The Yokogawa ALP111-S01 is a dedicated PROFIBUS-DP Communication Module for CENTUM VP and CS 3000 Distributed Control Systems (DCS). This module enables high-speed, bi-directional data exchange between Yokogawa Field Control Units (FCU) and PROFIBUS-compliant field devices, such as motor starters, frequency converters, and remote I/O stations. As a 100% Brand New original product made in Japan, it ensures deterministic control in demanding industrial environments.

Technical Specifications

Engineering Advantages

• Seamless Field Device Integration: The ALP111-S01 integrates PROFIBUS-DP slaves with the CENTUM VP system, eliminating complex wiring and reducing commissioning costs.

• Deterministic Real-Time Control: Independently processes PROFIBUS cyclic data, ensuring predictable, high-speed control of devices like motors and valves.

• Robust Hardware Reliability: Built in Japan with industrial-grade components, the ALP111-S01 is designed to withstand vibration and thermal fluctuations in process environments.

• Simplified Troubleshooting: Built-in diagnostics report device status and bus health directly to the Human Interface Station (HIS), reducing Mean Time to Repair (MTTR).

FAQs

Does the ALP111-S01 support redundancy?

Yes, two ALP111-S01 modules can be configured in a duplexed setup for redundancy, ensuring uninterrupted PROFIBUS-DP network communication in case of failure.

How many PROFIBUS slaves can a single ALP111-S01 module manage?

A single module can manage up to 125 slave devices, depending on your application’s data volume and cycle time.

Is this a genuine Yokogawa part made in Japan?

Yes, the ALP111-S01 is a genuine Yokogawa part, 100% Brand New, with "Made in Japan" labeling and original serial numbers.

What type of connector does the module use for the PROFIBUS link?

The module uses a 9-pin D-sub (RS-485) connector. We recommend shielded PROFIBUS cables and active terminators for optimal signal integrity.
