PROFIBUS DP-V1 and Redundancy

The CI840 operates as a PROFIBUS DP-V1 slave on the fieldbus connection to the controller. The module supports both line redundancy and module redundancy, allowing the S800 I/O configuration to use redundant communication paths and interface modules.

For redundant I/O installations, ABB specifies the TU846 module termination unit. For non-redundant I/O installations, the TU847 termination unit applies. The CI840 also supports Hot Swap and Hot Configuration In Run functions, subject to the installed system configuration.

The FCI manages I/O module configuration and signal-related processing. It also gathers supervision information and supports OSP handling. In addition, the interface provides HART pass-through for compatible I/O configurations.

Frequently Asked Questions (FAQ)

Q: Which communication protocol does the CI840 use?

A: The CI840 communicates with the controller through the PROFIBUS DP-V1 fieldbus and operates as a slave device.

Q: Which termination unit is specified for redundant I/O?

A: ABB specifies the TU846 for redundant I/O. The TU847 is specified for non-redundant I/O.

Q: Does the CI840 support module and line redundancy?

A: Yes. The supplied specifications identify both line redundancy and module redundancy as supported functions.

Field Installation Guidelines

Install the CI840 on the specified S800 I/O termination unit and verify mechanical engagement before applying power.

Use the TU846 when the application requires redundant I/O. Use the TU847 for non-redundant I/O configurations.

Route PROFIBUS communication wiring separately from high-voltage power conductors and high-current switching circuits. Maintain appropriate separation to reduce electromagnetic interference.

Terminate cable shields according to the approved system grounding design. Avoid creating unintended ground loops through multiple shield connection paths.

Confirm the available 24 V supply can support the CI840 load and the complete connected I/O assembly. The typical CI840 consumption is 190 mA at 24 V.

Before commissioning, verify PROFIBUS addressing, redundancy configuration, termination settings, and controller configuration against the approved system design.

Observe the specified ambient temperature and humidity limits during installation. For vertical mounting, keep the ambient temperature within the stated 40 deg C maximum.

Maintain the IP20 installation environment and protect the module from conductive contamination, excessive moisture, and mechanical damage.
