Product Overview

ABB CI871K01 3BSE056767R1 is a PROFINET IO Communication Interface designed for ABB System 800xA and AC 800M automation systems.

ABB’s product catalog identifies CI871K01 specifically as a PROFINET IO Communication Interface. The K01 package includes the CI871 communication interface and TP867 baseplate, providing the hardware needed to integrate PROFINET IO communication into the ABB control system.

The module is intended for industrial control applications where AC 800M controllers need to communicate with PROFINET IO devices. It is therefore better described as a communication interface rather than a generic PLC module.

Key Technical Specifications

ABB documentation confirms the CI871K01 package configuration and its 3BSE056767R1 article number.

Main Function

The CI871 provides the communication interface between an ABB AC 800M control system and PROFINET IO devices.

It can be used as part of an automation network where PROFINET-compatible field devices need to exchange process data with the control system. This makes the module useful for integrating distributed field equipment into an existing ABB System 800xA architecture.

The TP867 baseplate is included as part of the CI871K01 package according to ABB’s catalog documentation.

Typical Applications

• ABB System 800xA automation systems
• AC 800M controller installations
• PROFINET IO networks
• Industrial process control
• Factory automation
• Distributed field-device communication
• PLC and DCS network integration
• Replacement of existing CI871K01 hardware

Installation & Configuration

Before replacement, verify the complete ABB article number and hardware identification on the existing unit.

Recommended procedure:

1. Record the existing CI871 hardware and configuration information.
2. Confirm the replacement is CI871K01 / 3BSE056767R1.
3. Isolate the relevant control-system power according to site procedures.
4. Install the CI871 with the correct TP867 baseplate.
5. Check the network connection and PROFINET device configuration.
6. Restore the controller configuration.
7. Verify communication with the configured PROFINET IO devices.
8. Check system diagnostics and communication status before returning the system to normal operation.

Configuration should be performed using the engineering environment and system version appropriate to the installed System 800xA / AC 800M system.

Maintenance Recommendations

Keep the communication module clean and protected from dust, moisture, vibration and electrostatic discharge.

When replacing a CI871, record the original network configuration before removing the existing module. Pay particular attention to PROFINET device configuration and controller project settings.

If communication problems occur after replacement, check the following first:

• Module seating and baseplate connection
• Network cabling
• PROFINET configuration
• Device configuration
• Controller diagnostics
• Module status indicators
• System software compatibility

A replacement communication module should not be commissioned based only on matching physical appearance; the complete ABB type designation and system configuration should be verified.
