System Architecture & Signal Flow
The AIP171 occupies a standard slot within the CENTUM CS/VP Field Control Station (FCS) I/O nest. Field wiring (4–20 mA transmitters or 1–5 V DC sources) terminates at the associated terminal board. The AIP171 conditions, isolates, and digitizes each analog channel, transmitting engineering-unit values to the FCS controller via the internal V-net/IP or ESB bus. The FCS then makes these values available to the Human Interface Station (HIS) and historian in real time. The module supports YOKOGAWA’s standard diagnostic functions including open-wire detection and out-of-range alarming.
