The YOKOGAWA AIP521 is a Control Bus coupler used in the Yokogawa CENTUM VP distributed control system (DCS). The CENTUM VP is a modular and scalable system that can be used in a wide variety of industrial applications, including oil and gas production, power generation, chemical processing, and food and beverage processing. The AIP521 provides a communication bridge between the CENTUM VP controller and the field devices, allowing the controller to monitor and control the process.
The AIP521 is a high-performance coupler that supports a variety of communication protocols, including Yokogawa's own VL-NET and VNET protocols as well as Modbus, Profibus, and DeviceNet. It also supports a variety of field devices, including sensors, actuators, and valves.
The AIP521 is a rugged and reliable coupler that is designed to withstand harsh environmental conditions. It is also easy to install and maintain, making it a popular choice for engineers and technicians.

Communication with HART Devices
The analog I/O modules (with HART communication function) communicate with field devices and store analog data and HART variables in the Input/Output image area in the communication module. An FCS refers to and sets the Input/Output image by accessing the analog I/O modules (with HART communication function). The FCS utilizes the field device data via I/O terminals of the function block in the same way as other analog/digital I/O signals.
