Technical Specifications Back‑plane controller bus interface, AF100 fieldbus physical port. Auxiliary power 24 V DC, typical power consumption 4.2 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%.
Functional Features Exchanges data with controller via back‑plane bus. Processes AF100 fieldbus protocol. Acquires signal data from distributed S800 I/O stations. Transmits controller output commands to remote I/O modules. Front‑panel LED indicates AF100 bus link and module fault status. Built‑in hardware self‑diagnosis detects fieldbus link failure and internal circuit faults.
Application Scenarios Legacy AF100 bus spare part for ABB DCS system. Used for maintenance of old‑site remote S800 I/O control cabinets.
Performance Parameters Stable AF100 bus data transmission capability. Compatible with early S800 I/O hardware versions. Reliable bus fault detection function.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. AF100 protocol processing and signal driving assemblies. Back‑plane plug‑in connector and AF100 bus port.
Structural Characteristics Standard rack plug‑in module. Front side equipped with AF100 bus port and status LED indicators. Rear side fitted with back‑plane bus connector. Weight approximately 0.41 kilogram.
Working Principle Module completes hardware initialization after power‑on. It polls each remote S800 I/O station over AF100 bus. Field signal data is uploaded to controller through back‑plane bus. Downstream control commands are forwarded to corresponding remote I/O modules. Diagnosis circuit monitors AF100 bus link and module hardware continuously.
Installation Requirements Insert CI810V1 into target rack slot and lock fixing latch. Connect AF100 dedicated bus cable to front‑end port. Confirm back‑plane connector is fully engaged. Restore power supply, configure bus parameters and verify communication of all remote I/O stations.
Usage Notes Confirm hardware version compatibility with existing S800 I/O racks. Use AF100 standard bus cables. Verify all field signal input and output after replacement.
