Description
‑ Installed in Advant OCS S100 standard rack, communicates with AC450 series controller via rack back‑plane bus, acts as the master station of MasterFieldbus field bus.
‑ Connects remote field I/O cabinets through dedicated MasterFieldbus cable, performs cyclic reading of field analog and binary input signals, and outputs control commands to remote I/O modules. Supports multi‑station bus networking, realizes distributed I/O expansion for Advant OCS system.
‑ Built‑in large‑capacity data buffer, improves bus communication stability under multi‑node concurrent access condition, reduces data loss risk.
‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware status; detects hardware fault, bus short‑circuit and bus‑off fault, reports fault word to Advant controller.
‑ Cannot run independently; must cooperate with Advant OCS S100 rack and AC450 series controller. CI570 3BSE001440R1 is dedicated MasterFieldbus master‑station controller board, cannot be substituted by general‑purpose communication modules.
‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED and report fault alarm to Advant controller.
‑ No local historical‑data storage; module status and fault codes need to be read through Advant configuration‑monitoring tool.
‑ Module hardware failure will cause MasterFieldbus bus breakdown; controller local logic keeps normal operation, but all remote field I/O stations lose communication, field data acquisition and control output fail.
‑ Back‑plane connector: inserts into S100 rack slot, connects to internal bus of Advant AC450 controller.
‑ External D‑Sub25 connector: connect dedicated MasterFieldbus bus cables to remote field I/O cabinets.
‑ Mounting：insert into Advant OCS S100 standard rack slot
‑ Operating Temperature：‑20 ℃ ~ +60 ℃
‑ Storage Temperature：‑40 ℃ ~ +85 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Protection Class：IP20, cabinet‑internal installation.
- CI570 MasterFieldbus controller module（3BSE001440R1）
Complementary parts: Advant OCS S100 rack, AC450 series controller, MasterFieldbus dedicated communication cables, remote I/O cabinets, Advant configuration monitoring tool.
‑ Cut off control cabinet auxiliary power before inserting or replacing this module. Use dedicated MasterFieldbus shielded cables, make correct bus terminal termination at both ends of the bus cable.
‑ For spare‑part replacement: verify full model CI570 and part‑number 3BSE001440R1; after installation check back‑plane power‑supply, verify cyclic data interaction between controller and each remote I/O station. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.
‑ Module fault will result in total communication failure of DCS system remote MasterFieldbus I/O stations.
Power, petrochemical, metallurgy old‑set Advant OCS DCS control cabinets; ABB Advant OCS system maintenance and spare‑part replacement; industrial spare‑part for MasterFieldbus bus master‑station control unit.
