Order No: CI867K01，物料号 3BSE043660R1

The CI867K01 3BSE043660R1 is S500 rack‑mount plug‑in complete communication kit for ABB AC800M / 800xA DCS system, the kit consists of CI867 communication module body and TP867 baseplate, power is supplied by CEX back‑plane bus without external power supply. It implements Modbus‑TCP industrial ethernet standard protocol, supports client(master) / server(slave) dual‑mode operation. Equipped with two independent RJ45 ethernet ports, channel1 is 10/100Mbit/s, channel2 is fixed 10Mbit/s half‑duplex, used for connecting AC800M controller to third‑party Modbus‑TCP equipment, including external PLC, comprehensive protection relays, intelligent instruments, remote IO modules and auxiliary monitoring subsystems, realizes bidirectional reading‑writing of process registers, alarm‑event transmission and signal mapping. This is discontinued legacy DCS spare‑part, widely used for maintenance replacement of power, petrochemical and metallurgy automation cabinets. It supports hot‑swap function。

‑ Power Supply：Power supplied from CEX back‑plane bus；typical current consumption 160mA@24VDC，typical power consumption 3.84W

‑ Mechanical Structure：standard S500 rack single‑slot plug‑in kit, matched with TP867 baseplate；overall weight approx 0.70 kg；dimension 127.5mm(D) × 59mm(W) × 185mm(H)

‑ On‑board Resources：Modbus‑TCP 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 female ethernet interfaces, CH1:10/100Mbit/s, CH2:10Mbit/s half‑duplex

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

‑ Core Function：Modbus‑TCP master/slave protocol processing, third‑party device register data mapping interaction, 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, PRIM/DUAL status indicator

‑ Weight：approx 0.70 kg

‑ Installed in S500 standard rack via TP867 baseplate, communicates with AC800M series controller through internal CEX bus. Maximum 12 CI867K01 modules can be configured on one CEX bus, subject to actual bus load of controller.

‑ Supports Modbus‑TCP client(master) and server(slave) dual working modes. Two ethernet channels work independently, cannot realize network line redundancy. Working as master station, it reads and writes Modbus register data of field third‑party equipment periodically; working as slave station, it uploads AC800M internal process variables to upper host monitoring system. Realizes bidirectional mapping between Modbus register address and Control Builder control variables, completes cyclic data collection and acyclic parameter access. Each channel supports multiple Modbus‑TCP slave devices.

‑ Built‑in data buffer guarantees stable transmission of industrial process data. Supports hot‑swap, module can be replaced without rack power‑off during maintenance, brief communication interruption will occur during swapping process.

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

‑ Cannot run independently; must cooperate with S500 rack, TP867 baseplate and AC800M series controller. CI867K01 3BSE043660R1 is complete kit version of CI867 module, module body cannot work alone without TP867 baseplate, cannot be substituted by general‑purpose ethernet 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 Modbus‑TCP communication breakdown; controller internal logic keeps normal operation, but data interaction with all connected Modbus‑TCP field devices fails.

‑ Back‑plane connector: inserts into S500 rack slot via TP867 baseplate, connects to CEX internal bus of AC800M controller.

‑ External dual RJ45 female connectors: connect industrial shielded ethernet cables to Modbus‑TCP third‑party device network.

‑ Mounting：insert into S500 standard rack single slot with TP867 baseplate

‑ Operating Temperature：‑20 ℃ ~ +55 ℃

‑ 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 Modbus‑TCP master‑slave working mode, register mapping list and IP communication parameters according to site project requirements, adopt industrial shielded ethernet cable for field wiring. Two ethernet ports are independent, this hardware does not support network line‑redundancy function. It is recommended to replace module together with TP867 baseplate for spare‑part maintenance.

‑ For spare‑part replacement: verify full model CI867K01 and part‑number 3BSE043660R1; after installation check back‑plane power‑supply, verify bidirectional cyclic data interaction between controller and Modbus‑TCP field devices. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.

‑ Module fault will result in communication failure of all Modbus‑TCP devices under corresponding network channel.

Power, petrochemical, metallurgy old‑set AC800M /800xA DCS control cabinets; access third‑party PLC, comprehensive protection relays, intelligent instruments via Modbus‑TCP protocol; industrial spare‑part for Modbus‑TCP protocol gateway complete‑kit unit.
