Description
Application Scenarios:In a large pharmaceutical plant’s batch processing facility, the need to integrate a new purification skid’s 150+ I/O points into the existing Advant OCS presented a challenge. The central AC 450 controller’s local I/O capacity was exhausted. The solution was installing a remote cabinet near the new skid, equipped with an ABB S200-IT8 module acting as the intelligent gateway. The S200-IT8 managed all the local S800 I/O modules, processed interlocks locally for faster response, and communicated seamlessly with the main controller over the high-speed Advant Fieldbus (AF 100). This distributed architecture reduced wiring costs by 40%, improved control loop performance, and allowed the new unit to be integrated without any modification to the central control room hardware.
