Product Details

The Yokogawa ALP111-S00 is a high-performance PROFIBUS-DP Communication Module designed for the CENTUM VP and CS 3000 Distributed Control Systems (DCS). This module provides essential PROFIBUS-DP master functionality, allowing the Field Control Station (FCS) to manage and exchange data with a wide array of field devices. We supply this unit as 100% brand new and original in factory packaging, ensuring seamless integration and industrial-grade reliability for your FIO (Field I/O) units.

Product Overview

The ALP111-S00 operates as a dedicated communication gateway between Yokogawa's control stations and PROFIBUS-DP slave devices such as remote I/O, PLCs, and smart transmitters. By supporting the DP-V0 standard, this module facilitates deterministic data acquisition and control commands across the fieldbus. It offloads complex protocol management from the main processor, ensuring that your DCS maintains peak performance even when managing high-density fieldbus networks. This module is indispensable for plants utilizing multi-vendor field devices within a unified Yokogawa control environment.

Technical Specifications

Engineering Advantages

• High-Speed Determinism: The ALP111-S00 supports transmission speeds up to 12 Mbps. This allows for rapid I/O updates and minimizes loop latency, making it ideal for high-speed manufacturing and safety-critical process controls.

• Isolated Signal Integrity: The EIA-RS-485 interface features full signal isolation. This hardware barrier prevents ground loops and protects the DCS backplane from electrical surges and EMI noise generated by field-side equipment.

• Versatile Deployment: The module fits into a wide variety of Yokogawa node units, including the ANB10 (ESB bus) and ANR10 (ER bus). This flexibility enables engineers to place PROFIBUS-DP master functionality exactly where the field density requires it.

• Long-Distance Connectivity: By supporting lower baud rates, the module facilitates communication segments up to 1.2 km. This eliminates the need for expensive repeaters in large-scale plant layouts.

• FIO System Efficiency: The compact 2.2 cm width allows for maximum card density within the FIO rack. This reduces the total number of node units required, lowering the overall cost of the control system infrastructure.

FAQs

Does the ALP111-S00 support the DP-V1 or DP-V2 standard?

The ALP111-S00 is primarily compliant with the PROFIBUS-DP V0 standard. It focuses on high-speed cyclic data exchange (Input/Output data). For applications requiring acyclic communication (DP-V1), please verify your specific DCS software revision and GSD file requirements.

Can I install this module in an active Field Control Unit?

Yes, Yokogawa FIO modules generally support hot-swapping within redundant configurations. However, we recommend following the procedure outlined in the CENTUM VP hardware manual to ensure the bus remains stable during the insertion of a new ALP111-S00 module.

What is the maximum number of slave devices per module?

The ALP111-S00 can theoretically address the standard PROFIBUS limit of 126 devices; however, the actual number of connected slaves depends on the bus speed, the amount of data per slave, and the DCS station's total I/O capacity.

Is there a specific cable required for the 12 Mbps speed?

Yes. To achieve speeds up to 12 Mbps, you must use PROFIBUS-certified Type A shielded twisted-pair cable. Standard RS-485 cable may not provide sufficient signal integrity for the higher frequency data rates supported by the ALP111-S00.
