Product Overview
The YOKOGAWA AIP171 is a high-reliability transceiver control module engineered by Yokogawa, a global leader in industrial automation and DCS (Distributed Control System) solutions. Specifically designed for Yokogawa’s CENTUM VP DCS—a cornerstone system in petrochemical, power generation, and large-scale manufacturing industries—the AIP171 serves as the critical communication hub for V-Net (Yokogawa’s proprietary industrial bus) repeater systems. Its core function is to enable stable, long-distance data transmission between V-Net repeaters and transceiver units, ensuring seamless flow of control signals, process data, and diagnostic information across large industrial facilities.
Compliant with industrial-grade standards for environmental resilience, the AIP171 operates reliably in harsh conditions with electrical interference and temperature fluctuations. Key features include high-speed data transfer (up to 10 Mbps), redundant configuration support, and comprehensive diagnostic tools—all of which minimize network downtime and ensure uninterrupted operation of mission-critical processes. Whether extending communication distances to 4 kilometers in offshore platforms or maintaining fault tolerance in refineries, the YOKOGAWA AIP171 is an indispensable component for scaling CENTUM VP DCS networks while preserving data integrity.

Key Features and Benefits
The YOKOGAWA AIP171 delivers targeted value for industrial network scalability and reliability, with features optimized for large-scale CENTUM VP DCS deployments:
Long-Distance, High-Speed Communication
With support for optical V-Net transmission, the AIP171 extends communication distances up to 4 kilometers—critical for large facilities like oil refineries, where control rooms may be located far from field equipment. Its 10 Mbps data transfer rate ensures real-time transmission of process control signals and sensor data, avoiding delays that could impact process stability. For example, in a combined-cycle power plant, the AIP171 can link turbine sensors (located 3 km from the control room) to the CENTUM VP DCS without signal degradation.
Redundant Configuration for Fault Tolerance
The AIP171 can be configured as a redundant pair (1+1), meaning if one module fails, the backup automatically takes over—eliminating single points of failure in the network. This is essential for safety-critical applications like petrochemical distillation, where network outages could lead to process upsets or safety hazards. The module’s seamless failover ensures zero data loss and uninterrupted operation, aligning with industry requirements for 99.99% network availability.
Comprehensive Diagnostics for Rapid Troubleshooting
Built-in diagnostic tools simplify network maintenance and reduce downtime. The AIP171 provides real-time status monitoring via LED indicators (e.g., power, communication link, fault) and logs detailed fault information (e.g., signal loss, module overheating) that can be accessed through the CENTUM VP HMI. Loopback testing allows technicians to verify module functionality without disconnecting field wiring, cutting troubleshooting time by up to 60%. This is particularly valuable in remote locations like offshore platforms, where on-site maintenance is costly and time-consuming.
