Product Overview

ABB CI871A 3BSE092693R1 is an AC 800M communication interface that connects PROFINET IO devices to the System 800xA control environment through Ethernet. It acts as the PROFINET IO master, while the TP867 baseplate provides the physical module position and the CEX-Bus carries the interface logic and supply distribution.

The Ethernet path uses the CH1 RJ-45 connector on the TP867 baseplate for the PROFINET IO network. ABB CI871A 3BSE092693R1 receives its required voltage from the +24 V supply through the CEX-Bus DC/DC converter, so the communication interface and its baseplate remain one installed hardware path rather than two independent field devices.

Within a controller station, ABB CI871A 3BSE092693R1 supports module redundancy and hot swap. The interface is intended for the stated System 800xA software releases and operates in a 0 to +55 °C environment with IP20 protection and 5 to 95 percent non-condensing humidity.

Communication and Connectivity

ABB CI871A 3BSE092693R1 moves controller data to PROFINET IO devices through the Ethernet interface.

PROFINET master role

The CI871A is the master on the PROFINET IO network and coordinates the connected IO device communication.

RJ-45 network path

The CH1 RJ-45 connector on the TP867 baseplate is the physical Ethernet connection used for PROFINET IO.

10/100 Mbit/s link

The interface supports 10/100 Mbit/s transmission, matching the network segment and switch used with the controller station.

System Integration

ABB CI871A 3BSE092693R1 sits on the AC 800M CEX-Bus and joins the controller, baseplate, Ethernet switch and PROFINET IO field devices.

CEX-Bus position

The expansion unit contains the CEX-Bus logic, communication unit and DC/DC converter that feeds the interface.

Redundant module option

Module redundancy is supported, while line redundancy is not; the network topology must therefore reflect the selected redundancy method.

Baseplate and controller

The CI871A works with the TP867 baseplate and is intended for the stated AC 800M controller environment rather than a standalone Ethernet panel.
