ABB CI873K01 3BSE058899R1 Communication Interface Kit

‑ Power Supply：Power supplied from CEX bus；typical power consumption 4.0W

‑ Mechanical Structure：standard S500 rack single‑slot plug‑in kit, matched with TP830 baseplate；overall weight approx 0.65 kg

‑ On‑board Resources：EtherNet/IP scanner protocol processing unit, dual‑channel ethernet driving circuit, data buffer memory, CEX back‑plane bus controller, module self‑diagnosis circuit

‑ Communication Interface：internal CEX bus for data interaction with AC800M controller；two independent RJ45 ethernet interfaces, CH1:10/100Mbit/s, CH2:10Mbit/s half‑duplex

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

‑ Core Function：EtherNet/IP scanner(master) station data processing, third‑party EtherNet/IP device register data mapping interaction, support module redundancy, bus fault diagnosis, hot‑swap support

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

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

‑ Weight：approx 0.65 kg

‑ Installed in S500 standard rack via TP830 baseplate, communicates with AC800M series controller through internal CEX bus. Single CEX bus supports maximum 12 CI873K01 modules, subject to actual bus load of controller.

‑ Operates as EtherNet/IP scanner(master) station, communication rate 10/100Mbit/s adaptive. Single module supports maximum 128 EtherNet/IP slave devices, needs to import EDS device description file in Control Builder engineering software. Realizes bidirectional mapping between EtherNet/IP peripheral process data and Control Builder control variables, completes cyclic real‑time I/O data collection and non‑cyclic parameter reading‑writing and equipment fault diagnosis. This module supports module‑level redundancy configuration, hardware itself does not support network line redundancy, field network redundancy needs to be realized by external industrial switch. Two ethernet ports work independently, cannot be used for link redundancy.

‑ Built‑in data buffer guarantees real‑time performance of EtherNet/IP cyclic process data. Supports hot‑swap, module can be replaced without rack power‑off during maintenance, brief communication interruption will occur in swapping process.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware integrity; detects hardware fault and EtherNet/IP ethernet communication abnormality, reports fault word and alarm information to AC800M controller.

‑ Cannot run independently; must cooperate with S500 rack, TP830 baseplate and AC800M series controller. CI873K01 3BSE058899R1 is complete kit version including CI873 module and TP830 baseplate, module body cannot work alone without baseplate. Different from later upgraded CI873AK01, CI873AK01 matches TP867 baseplate and requires higher 800xA system software versionABB.

‑ 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 EtherNet/IP network communication breakdown; controller internal logic keeps normal operation, but data interaction with all connected EtherNet/IP field slave devices fails.

‑ Back‑plane connector: inserts into S500 rack slot via TP830 baseplate, connects to CEX internal bus of AC800M controller.

‑ External dual RJ45 connectors: connect industrial shielded ethernet cables and industrial switch to EtherNet/IP field equipment network.

‑ Mounting：insert into S500 standard rack single slot with TP830 baseplate

‑ Operating Temperature：‑20 ℃ ~ +60 ℃

‑ Storage Temperature：‑40 ℃ ~ +85 ℃

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

‑ Pollution degree：Degree 2

‑ Protection Class：IP20, cabinet‑internal installation.

‑ Cut off control cabinet auxiliary power before inserting or replacing this module, although module supports hot‑swap, power‑off operation is recommended for spare‑part replacement. Configure EtherNet/IP device list, import EDS description file, set IP address and process‑signal mapping relation according to site project requirements, adopt industrial shielded ethernet cable for field wiring. Two ethernet ports are independent, hardware does not support network line‑redundancy function. It is recommended to replace module together with TP830 baseplate for spare‑part maintenance.

‑ For spare‑part replacement: verify full model CI873K01 and part‑number 3BSE058899R1; after installation check back‑plane power‑supply, verify real‑time cyclic data interaction between controller and EtherNet/IP field devices. Hardware‑version mismatch will bring risk of communication parsing abnormality.

‑ Module fault will result in communication failure of all EtherNet/IP slave devices under corresponding network channel.
