Product introduction
The YOKOGAWA AIP571 is an essential electrical transceiver Remote I/O (RIO) module within the YOKOGAWA CENTUM VP distributed control system. Unlike a typical analog input module that directly processes field signals, the YOKOGAWA AIP571‘s primary role is to facilitate high-speed, long-distance communication. It establishes a link between the RIO I/O modules, which are located closer to the process field, and the Field Control Unit (FCU), which houses the main control logic. This architecture allows for a decentralized control system, reducing field wiring costs and simplifying installation in large, geographically dispersed plants. The YOKOGAWA AIP571 uses optical fiber cable as its communication medium, offering excellent resistance to electromagnetic interference (EMI) and enabling data transmission over significant distances without signal degradation. This makes the YOKOGAWA AIP571 a fundamental building block for a scalable and resilient automation infrastructure. The module’s design is optimized for high reliability, ensuring that critical data communication remains uninterrupted, a key requirement for complex process control applications.
Core advantages and technical highlights
The YOKOGAWA AIP571 transceiver module offers distinct advantages centered on communication reliability and system architecture flexibility. A standout feature is its support for dual-redundant ESB bus configuration. This provides a backup communication path, meaning if one link fails, the system can seamlessly switch to the redundant path, preventing system downtime and ensuring continuous process control. This level of reliability is paramount for industries where interruptions can lead to significant financial losses or safety hazards. The use of optical fiber communication is another key technical highlight. Optical fiber offers immunity to electrical noise, which is common in industrial environments, and allows for much longer communication distances than traditional copper wiring. This extends the reach of the DCS, enabling the YOKOGAWA AIP571 to connect remote I/O subsystems located far from the main control room. The high-speed data transfer capability (up to 100 Mbps) ensures that process data is delivered to the FCU with minimal latency, allowing for real-time monitoring and control. Furthermore, the module’s robust construction and wide operating temperature range (-20°C to 70°C) make the YOKOGAWA AIP571 suitable for deployment in harsh industrial conditions, from cold utility rooms to hot, dusty plant floors.
Typical application scenario
The YOKOGAWA AIP571 is crucial in large-scale process automation projects where the control system needs to be distributed across a wide area. Its core application is within the YOKOGAWA CENTUM VP DCS platform, connecting remote field cabinets to the central controllers. Industries that heavily rely on the YOKOGAWA AIP571 include oil and gas, petrochemicals, power generation, and chemical manufacturing. In a refinery, for example, the YOKOGAWA AIP571 would be used to link I/O modules collecting data from hundreds of pressure, temperature, and flow sensors scattered across a vast tank farm or processing unit to the main control center. Its long-distance optical communication capability eliminates the need for numerous control rooms or extensive copper wiring runs, significantly simplifying the system layout and reducing installation costs. Similarly, in a power plant, the YOKOGAWA AIP571 would be used to connect I/O modules at the boiler or turbine hall to the central control room, ensuring that real-time performance data is delivered reliably. This module’s ability to maintain high-speed, redundant communication in challenging environments makes the YOKOGAWA AIP571 an indispensable part of modern, large-scale industrial control systems.

Installation, commissioning and maintenance instructions
Installation of the YOKOGAWA AIP571 module is straightforward, though it requires attention to detail to ensure the integrity of the optical fiber communication. Before installation, confirm the power to the remote I/O unit and FCU is disconnected. The YOKOGAWA AIP571 is designed to fit into a specific slot on the relevant YOKOGAWA RIO carrier. The key step is connecting the optical fiber cables. These must be clean, correctly terminated, and securely plugged into the module’s optical ports to ensure a stable, high-speed link. During commissioning, the system software will be used to configure the YOKOGAWA AIP571 and confirm its communication status. Built-in diagnostic LEDs on the module provide immediate feedback on its operational health and communication link status.
For maintenance, the YOKOGAWA AIP571 is a solid-state component with no moving parts, so it requires minimal physical maintenance. The main focus should be on the optical fiber connections; these should be kept clean to prevent signal loss. Regularly inspect the cables and connections for any damage. The hot-swappable design of the YOKOGAWA AIP571 allows for a failed module to be replaced without shutting down the entire system, a critical feature for continuous processes. Troubleshooting typically involves checking the module’s status LEDs and the system’s diagnostic logs. A spare YOKOGAWA AIP571 should be kept on hand to facilitate rapid replacement in case of a failure, maximizing system uptime.
