Overview
Configured for PROFINET IO communication in ABB System 800xA, the ABB CI871AK01 (CI871A PROFINET IO Communication Interface) provides Ethernet-based communication between the AC 800M controller platform and PROFINET IO devices. The module uses the CH1 RJ45 interface on the TP867 baseplate for the PROFINET IO network and requires an Ethernet switch for network connection.

PROFINET IO and CEX-Bus Architecture
The CI871A handles PROFINET IO communication between the AC 800M system and connected PROFINET IO devices. The TP867 baseplate provides two RJ45 Ethernet connectors, while only CH1 supports the specified PROFINET IO connection.
The Ethernet cable connects the CI871A to the PROFINET IO network through an Ethernet switch. Therefore, the second RJ45 connector on the TP867 baseplate does not serve as the PROFINET IO interface described for this module.
Internally, the CI871 expansion unit contains CEX-Bus logic, a communication unit, and a DC/DC converter. The converter derives the required operating voltage from the +24 V supply through the CEX-Bus. The module supports module redundancy and hot swap operation within the applicable AC 800M system configuration.
The CI871A requires a compatible System 800xA software environment. The supplied compatibility information specifies System 800xA 6.0.3.3, 6.1.1, and subsequent versions.
Frequently Asked Questions (FAQ)
Q: Which Ethernet connector carries the PROFINET IO connection?
A: The CH1 RJ45 connector on the TP867 baseplate carries the PROFINET IO connection. The interface supports 10/100 Mbit/s Ethernet communication.
Q: Does the CI871A support line redundancy?
A: No. The supplied specifications identify line redundancy as unsupported. The module does support module redundancy.
Q: What power consumption does the CI871A require?
A: The specified typical consumption is 160 mA from the 24 V supply through the CEX-Bus arrangement.
Field Installation Guidelines
- Install the CI871A on the specified TP867 baseplate and verify that the module seats correctly on the CEX-Bus connection.
- Connect the Ethernet cable to the CH1 RJ45 connector designated for the PROFINET IO network.
- Route the Ethernet cable through the required industrial Ethernet network infrastructure and connect it through an Ethernet switch.
- Keep Ethernet communication cables separated from high-current power conductors and strong electromagnetic interference sources where practical.
- Maintain correct cable shielding and grounding practices according to the installed PROFINET network design and applicable site standards.
- Verify the +24 V supply and CEX-Bus connection before commissioning the communication interface.
- Confirm that the installed System 800xA software version meets the CI871A compatibility requirement.
- For redundant configurations, verify the module redundancy architecture and controller configuration before placing the system into service.
- Observe the specified operating temperature, humidity, pollution degree, corrosion protection, and altitude limits during installation.
- For hazardous-location installations, apply the applicable Zone 2 installation requirements and verify that the complete installation satisfies the stated certification conditions.
