System Architecture & Signal Flow
The IC660ERD025B connects to the Genius Bus via a single twisted-pair serial cable (daisy-chain topology). Each remote drop is assigned a unique device number (0–31) on the bus. The host PLC’s Bus Controller (e.g., IC660BBA020) polls each drop controller cyclically. The IC660ERD025B manages local I/O scanning, buffers input data, and transmits consolidated I/O images to the host controller within each bus scan cycle. This architecture decouples local I/O scan time from the host CPU scan, enabling scalable, high-point-count systems without degrading controller performance.
Typical Signal Flow: Field Device → Genius I/O Module → IC660ERD025B (Drop Controller) → Genius Bus → Host Bus Controller (IC660BBA020) → Series 90-60 CPU
