Function And Network Connection
Controller Interface
The CI871A expansion unit contains CEX-Bus logic, a communication unit and a DC/DC converter supplied from the +24 V CEX-Bus supply. It provides the AC 800M controller with PROFINET IO master communication.
Network Connection
The TP867 baseplate provides two RJ-45 Ethernet connectors, but ABB specifies CH1 as the PROFINET IO connection. Connect it to the PROFINET IO network through an Ethernet switch. ABB lists 10/100 Mbit/s transmission, module redundancy and hot swap; line redundancy is not supported.
System Compatibility And Installation Conditions
Applications
PROFINET IO Control
ABB identifies CI871A for connecting PROFINET IO devices to AC 800M controllers over industrial Ethernet. In System 800xA projects, it provides the controller-side PROFINET IO master interface for distributed devices and field communication networks.
Ethernet-APL Projects
ABB also documents CI871A as the native AC 800M PROFINET interface used with Ethernet-APL infrastructure and PROFINET proxy configurations. The topology, field switches, device profiles and engineering configuration must match the installed project.
Lifecycle And Replacement Guidance
Frequently Asked Questions
Is ABB CI871A Compatible With Every System 800xA Version?
No. ABB states that CI871A works with System 800xA 6.0.3.3, 6.1.1 and subsequent versions. Confirm the installed System 800xA and Compact Control Builder versions before ordering or replacing the interface.
Does ABB CI871A Support PROFINET IO Line Redundancy?
No. ABB lists line redundancy as not supported. The official data does list module redundancy as supported, so the network and controller architecture must be checked separately.
Can ABB CI871A Be Used In A Redundant Module Arrangement?
Yes. ABB lists module redundancy for CI871A. Verify the complete AC 800M controller configuration, firmware and engineering project before commissioning the redundant pair.
Which Ethernet Port Is Used On The ABB CI871A TP867 Baseplate?
ABB states that the TP867 has two RJ-45 Ethernet connectors, but only CH1, which supports 100 Mbit/s, is used for the PROFINET IO connection. Connect the interface to the PROFINET IO network through an Ethernet switch.
What Must Be Checked Before Replacing An Earlier ABB CI871 With CI871A?
Do not base the decision on the similar model name alone. Confirm the current CI871AK01 package and 3BSE092693R1 article number, TP867 baseplate, System 800xA and Compact Control Builder versions, CEX-Bus position, redundancy design, network settings and the approved project hardware definition.
Model Identification
Use the exact model CI871A. Current ABB identification also includes package CI871AK01 and article number 3BSE092693R1. Common search forms include "CI871A PROFINET card", "ABB CI871A interface" and "CI871 A"; verify the complete ABB label and project hardware definition before ordering.
