ABB CI547 Slave Communication Interface Module

‑ Power Supply：Supplied by rack back‑plane 24 VDC；typical power consumption 5.3 W

‑ Mechanical Structure：standard S500 rack plug‑in module；weight approx 0.47 kg

‑ On‑board Resources：DeviceNet protocol processing unit, CAN 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；5‑pin screw terminal DeviceNet field bus interface

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

‑ Core Function：DeviceNet slave‑station protocol processing, cyclic I/O data exchange, acyclic parameter access between controller and DeviceNet master device

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

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

‑ Weight：approx 0.47 kg

‑ Installed in S500 standard rack, communicates with AC800M series controller via rack back‑plane bus.

‑ Works as DeviceNet slave node, supports auto‑baud‑rate detection including 125kbps,250kbps,500kbps. Receives cyclic output data from DeviceNet master station, transmits controller process input data to master station. Supports acyclic message for parameter reading and writing.

‑ Configurable I/O data length, maximum input 511 bytes, maximum output 511 bytes. Built‑in data buffer reduces bus data‑loss risk.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware status; detects hardware fault and bus‑off fault, reports fault word to AC800M controller.

‑ Cannot run independently; must cooperate with S500 rack and AC800M controller. CI547 3BSE012546R1 is dedicated DeviceNet slave communication board, cannot be substituted by general‑purpose CAN communication modules.

‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED and report fault alarm 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 DeviceNet slave‑station communication breakdown; controller internal logic keeps normal operation, but data interaction with DeviceNet master‑station equipment fails.

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

‑ External DeviceNet terminal: connect dedicated DeviceNet bus cables to master‑station equipment.

‑ 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. Set station address and baud rate according to site DeviceNet network requirements, use DeviceNet‑compliant shielded bus cables.

‑ For spare‑part replacement: verify full model CI547 and part‑number 3BSE012546R1; after installation check back‑plane power‑supply, verify bidirectional cyclic‑data interaction between controller and DeviceNet master‑station. Hardware‑version mismatch will bring risk of communication parsing abnormality.

‑ Module fault will result in failure of DCS system DeviceNet slave‑station communication channel.
