Description
‑ Power Supply：Power supplied from CEX bus；typical power consumption 5.0W
‑ Mechanical Structure：standard S500 rack single‑slot plug‑in module；weight approx 0.45 kg
‑ On‑board Resources：DriveBus protocol processing unit, optical fiber transceiver 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 optical fiber DriveBus interfaces
‑ Galvanic Isolation：optical isolation between DriveBus bus side and controller internal logic side, realize complete electrical isolation
‑ Core Function：DriveBus optical bus master‑station processing, multi‑drive high‑speed coordinated control data exchange, drive status collection, drive control command output, bus fault diagnosis, hot‑swap support
‑ Protection：optical‑port anti‑interference protection
‑ Status LED Indicators：Power indicator, Module Fault indicator, DriveBus bus communication status LED
‑ Weight：approx 0.45 kg
‑ Installed in S500 standard rack, communicates with AC800M series controller via rack internal CEX bus. Single AC800M controller supports maximum 2 sets of CI858‑1 modules.
‑ Operates as DriveBus optical bus master station, communication rate 8Mbit/s. Single CI858‑1 module supports maximum 24 ABB drive units. When multi‑drive networking, it needs to cooperate with NDBU branch unit to realize star‑topology bus layout. Realizes high‑speed real‑time transmission of drive speed‑setting, torque command, meanwhile collects drive running current, torque, fault alarm, status feedback information, satisfies multi‑motor synchronous coordinated control requirement for rolling mill and paper‑machine.
‑ Built‑in data buffer guarantees high‑speed real‑time performance of drive bus. Supports hot‑swap, module can be replaced without rack power‑off during maintenance, short‑time drive communication interruption will occur in swapping process.
‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware integrity; detects hardware fault and DriveBus optical‑bus communication abnormality, reports fault word to AC800M controller.
‑ Cannot run independently; must cooperate with S500 rack and AC800M series controller. CI858‑1 3BSE018137R1 is dedicated DriveBus optical‑fiber drive communication board, cannot be substituted by general‑purpose PROFIBUS communication modules. No line‑redundancy function.
‑ 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 DriveBus optical bus communication breakdown; controller internal logic keeps normal operation, but data interaction with all connected ABB drive devices fails.
‑ Back‑plane connector: inserts into S500 rack slot, connects to CEX internal bus of AC800M controller.
‑ External optical fiber interfaces: connect dedicated DriveBus optical fiber cables and NDBU branch units to field ABB drive equipment.
‑ Mounting：insert into S500 standard rack single slot
‑ 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.
- CI858‑1 DriveBus communication interface module（3BSE018137R1）
Complementary parts: S500 rack, AC800M series controller, DriveBus dedicated optical fiber cables, NDBU branch unit, field ABB drive equipment, Control Builder configuration monitoring tool.
‑ 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 drive device list and drive signal mapping relation according to site multi‑drive project requirements, use matched DriveBus dedicated optical fiber, correctly configure NDBU branch unit. This module has no bus line‑redundancy function.
‑ For spare‑part replacement: verify full model CI858‑1 and part‑number 3BSE018137R1; after installation check back‑plane power‑supply, verify high‑speed cyclic data interaction between controller and each field drive. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.
‑ Module fault will result in communication failure of all drive devices on corresponding DriveBus optical bus.
