Product Introduction

The ABB CI871, part number 3BSE056767R1, is a complete PROFINET IO communication interface kit for ABB AC800M and 800xA distributed control systems. The kit includes CI871 communication interface module and TP867 baseplate. It enables the AC800M controller to work as PROFINET IO controller, realizing real-time bidirectional data exchange between DCS and field PROFINET devices, such as remote I/O units, variable frequency drives and smart field instruments. Supporting 10/100Mbps industrial Ethernet, it adopts industrial circuit design and strong EMC anti-interference capability. It can run reliably in tough industrial environments with temperature fluctuation, dust, mechanical vibration and electromagnetic noise. Widely used in power, petrochemical, pulp & paper, metallurgy and water treatment industries. It is a key spare part for AC800M rack maintenance, communication module replacement and DCS network upgrade.

Content Details

Brand: ABB Model: CI871 Part No: 3BSE056767R1 Product Type: PROFINET IO Communication Interface Kit Applicable System: ABB AC800M / 800xA DCS Protocol: PROFINET IO Transmission Rate: 10/100 Mbps Package Content: CI871 communication module + TP867 baseplate The ABB CI871 3BSE056767R1 kit is installed in AC800M control rack. It connects the controller CEX bus with PROFINET IO industrial Ethernet network. It collects field device data and transmits control commands from DCS controller to PROFINET field equipment, achieving deterministic real-time communication for process control. Dual RJ45 Ethernet ports provide flexible network wiring options to meet different site network layouts. This module supports hot-swap function. Maintenance engineers can replace the module without stopping the whole control rack, effectively reducing system downtime during overhaul. It also supports module redundancy configuration to improve system reliability for high-risk process sites. Every unit undergoes full function test and aging screening before shipment to guarantee stable 24/7 continuous operation. Built-in isolation protection suppresses surge and ground loop interference, protecting the main controller from electrical damage. Optimized EMC design reduces noise interference generated by high-power motors and inverters. It can be configured and diagnosed via ABB Control Builder software. LED indicators on front panel show power status, network link and data transmission activity, helping maintenance staff quickly identify network communication faults. It can connect multiple PROFINET IO field devices and expand the communication capacity of AC800M controller. Typical application scenarios include thermal power plant DCS control, chemical continuous process monitoring, paper mill automation, metallurgical production line and municipal sewage treatment automation. When the original PROFINET communication module fails, CI871 3BSE056767R1 can be directly replaced to restore PROFINET IO network communication between DCS and field instruments. This module meets CE, UL and IEC industrial safety standards with IP20 protection rating. Compact modular design and durable electronic components support long-term continuous operation. Whether for spare inventory of equipment maintenance or component procurement for DCS renovation projects, the ABB CI871 PROFINET IO communication kit delivers stable and reliable industrial Ethernet connection for your AC800M automation system.
