ABB CI830 3BSE013252R1 Communication Interface Module

‑ Power Supply：Supplied by S800 rack back‑plane 24 VDC；typical power consumption 4.8 W

‑ Mechanical Structure：standard S800 I/O rack plug‑in module；weight approx 0.50 kg

‑ On‑board Resources：PROFIBUS DP‑V1 protocol processing unit, bus driving circuit, data buffer memory, internal ModuleBus interface, module self‑diagnosis circuit

‑ Communication Interface：internal ModuleBus bus for data interaction with S800 I/O modules；D‑Sub9 PROFIBUS DP‑V1 external bus interface

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

‑ Core Function：PROFIBUS DP‑V1 slave‑station protocol processing, cyclic I/O data transmission, DP‑V1 acyclic parameter access, hardware and channel fault diagnosis

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

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

‑ Weight：approx 0.50 kg

‑ Installed in S800 I/O standard rack, communicates with S800 series I/O modules via rack internal ModuleBus, operates as PROFIBUS DP‑V1 slave node.

‑ Supports PROFIBUS baud rate from 9.6 kbit/s up to 12 Mbit/s. Cyclically uploads field input signals collected by S800 I/O modules to PROFIBUS master station, receives output control commands from master station and distributes to corresponding S800 output modules. Supports DP‑V1 acyclic service for parameter configuration and fault diagnosis access.

‑ Built‑in data buffer improves bus transmission stability, provides abundant diagnostic information including bus short‑circuit, station address error, module hardware failure.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware integrity; detects hardware fault and bus‑off fault, reports fault status through LED indicator and PROFIBUS diagnostic message.

‑ Cannot run independently; must cooperate with S800 I/O rack and S800 series I/O modules. CI830 3BSE013252R1 is dedicated PROFIBUS DP‑V1 slave communication board, cannot be substituted by general‑purpose PROFIBUS communication modules.

‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED, fault information can be read through PROFIBUS diagnostic message.

‑ 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 S800 I/O cluster lose PROFIBUS bus communication; all I/O signals under this CI830 cluster cannot complete data interaction with PROFIBUS master‑station equipment.

‑ Back‑plane connector: inserts into S800 I/O rack slot, connects to internal ModuleBus of S800 I/O cluster.

‑ External D‑Sub9 connector: connect PROFIBUS shielded bus cables to PROFIBUS DP master‑station device.

‑ Mounting：insert into S800 I/O 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 PROFIBUS slave station address according to site network requirements, use standard PROFIBUS shielded cables, install terminal resistor at both ends of PROFIBUS bus trunk. Baud rate setting must keep consistent with PROFIBUS master station.

‑ For spare‑part replacement: verify full model CI830 and part‑number 3BSE013252R1; after installation check back‑plane power‑supply, verify cyclic data interaction between S800 I/O cluster and PROFIBUS DP master‑station. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.

‑ Module fault will result in total communication failure of corresponding S800 I/O cluster on PROFIBUS network.
