ABB CI687K01 3BSE043660R1 Fieldbus Communication Interface Module

‑ Power Supply：Supplied by rack back‑plane 24 VDC；typical power consumption 7.2 W

‑ Mechanical Structure：standard S500 rack plug‑in module；weight approx 0.75 kg

‑ On‑board Resources：AF100 bus protocol processing unit, dual‑channel bus driving circuit, data buffer memory, back‑plane bus controller, module self‑diagnosis circuit

‑ Communication Interface：internal back‑plane bus for data interaction with AC800M controller；dual‑channel AF100 bus interface

‑ Galvanic Isolation：galvanic isolation between external AF100 bus side and controller internal logic side, isolation rating 2500 VAC

‑ Core Function：AF100 field‑bus protocol processing, dual‑channel bus redundancy support, cyclic data transmission between controller and remote S800 I/O stations

‑ Protection：bus‑port surge‑suppression and ESD protection

‑ Status LED Indicators：Power indicator, Module Fault indicator, PRIM、DUAL, bus sending‑receiving status LED

‑ Weight：approx 0.75 kg

‑ Installed in S500 standard rack, communicates with AC800M series controller via rack back‑plane bus. Supports AF100 bus primary‑standby dual‑channel redundancy, when main channel fails, it can automatically switch to standby channel to ensure bus communication continuity.

‑ Connect remote S800 I/O cabinets through AF100 dedicated bus cable, cyclically collect field analog and binary input signals, and send control output commands to remote I/O modules. Realizes distributed I/O expansion for AC800M system.

‑ Built‑in large‑capacity data buffer, improves bus communication stability under multi‑node concurrent access condition, reduces data loss risk.

‑ Module self‑diagnosis monitors back‑plane power‑supply, on‑board hardware integrity and dual‑channel bus running state; detects hardware fault, bus short‑circuit and bus‑off fault, reports fault word to AC800M controller.

‑ Cannot run independently; must cooperate with S500 rack and AC800M series controller. CI687K01 3BSE043660R1 is dedicated AF100 bus communication board, cannot be substituted by general‑purpose communication modules.

‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED and report fault alarm word to AC800M controller.

‑ No local historical‑data storage; module status and fault codes need to be read through Control Builder configuration‑monitoring tool.

‑ Module hardware failure will cause AF100 bus communication breakdown; controller local logic keeps normal operation, but all remote S800 I/O stations lose communication, field data acquisition and control output fail.

‑ Back‑plane connector: inserts into S500 rack slot, connects to internal bus of AC800M controller.

‑ External AF100 bus interface: connect dedicated AF100 shielded bus cables to remote S800 I/O cabinets.

‑ Mounting：insert into S500 standard rack slot

‑ Operating Temperature：‑20 ℃ ~ +60 ℃

‑ Storage Temperature：‑40 ℃ ~ +85 ℃

‑ Relative Humidity：5‑95 %RH, non‑condensing

‑ Protection Class：IP20, cabinet‑internal installation.

‑ Cut off control cabinet auxiliary power before inserting or replacing this module. Use dedicated AF100 shielded cables, complete bus terminal termination at both ends of the bus cable. When configuring redundancy function, set primary‑standby channel parameters according to site requirements.

‑ For spare‑part replacement: verify full model CI687K01 and part‑number 3BSE043660R1; after installation check back‑plane power‑supply, verify cyclic data interaction between controller and each remote S800 I/O station. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.

‑ Module fault will result in total communication failure of DCS system remote AF100 S800 I/O stations.
