ABB CI543 3BSE010699R1 Communication Interface Module

‑ Power Supply：Supplied by rack back‑plane 24 VDC；typical power consumption 5.0 W

‑ Mechanical Structure：standard S100 rack plug‑in module；weight approx 0.45 kg

‑ On‑board Resources：serial protocol processing unit, signal driving circuit, data buffer unit, back‑plane bus interface, module self‑diagnosis circuit

‑ Communication Interface：internal back‑plane bus for data exchange with Advant controller；external RS‑232‑C / RS‑485 serial interface

‑ Galvanic Isolation：galvanic isolation between external serial‑port side and control internal logic side, isolation rating 2500 VAC

‑ Core Function：GCOM bus protocol processing, serial‑port protocol conversion, bidirectional data transmission between controller and external equipment

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

‑ Status LED Indicators：Power indicator, Module Fault indicator, communication sending‑receiving status LED

‑ Weight：approx 0.45 kg

‑ Installed in Advant OCS S100 standard rack, communicates with Advant AC410 series controller via rack back‑plane GCOM bus.

‑ Provides isolated RS‑232‑C and RS‑485 external serial channels, completes protocol conversion, realizes bidirectional data exchange between controller and upper‑level monitoring station, field instrument and third‑party equipment.

‑ Built‑in data buffer, adapts to multi‑point serial bus communication scene, reduces data‑loss risk caused by bus conflict.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware status; detects hardware fault and communication abnormality, reports fault information to controller.

‑ Cannot run independently; must cooperate with Advant OCS rack and AC410 series controller. CI543 3BSE010699R1 belongs to dedicated GCOM communication board, cannot be substituted by general‑purpose serial communication modules.

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

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

‑ Module hardware failure will cause loss of GCOM serial communication channel; controller internal logic operation keeps normal, but serial‑port data interaction with external equipment fails.

‑ Back‑plane connector: inserts into S100 rack slot, connects to GCOM internal bus of Advant controller.

‑ External serial terminals: connect communication cables to operation station, field instruments and third‑party devices.

‑ Mounting：insert into Advant OCS S100 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. Set serial‑port baud rate, data bit, parity bit according to site requirements; parameter mismatch will lead to communication no‑data.

‑ For spare‑part replacement: verify full model CI543 and part‑number 3BSE010699R1; after installation check back‑plane power‑supply, verify bidirectional data interaction between controller and external serial‑devices. Hardware‑version mismatch will bring risk of communication‑parsing abnormality.

‑ Module fault will result in failure of DCS system GCOM serial communication channel.
