ABB CI851K01 3BSE018101R1 PROFIBUS-DP Communication Interface Module Kit

Configured for high-speed fieldbus data exchange in System 800xA and AC 800M platforms, the ABB CI851K01 3BSE018101R1 (CI851K01 PROFIBUS-DP Communication Interface Kit) provides direct physical/electrical execution. It links PROFIBUS-DP field networks to the controller backplane, processing deterministic network traffic from 9.6 kbit/s to 12 Mbit/s and mapping field device process variables directly into IEC 61131 application code.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

The CI851K01 module establishes a deterministic bridge between distributed PROFIBUS-DP field devices and the AC 800M controller backplane via the CEX bus. Operating across variable transmission speeds up to 12 Mbit/s, the module executes multi-master or master/slave protocol transactions without degrading backplane communication velocity. It supports module-level hardware redundancy configurations, enabling rapid failover transitions without resetting active control loops or interrupting neighboring CEX bus operations.

Frequently Asked Questions

Q: Does the CI851K01 module require an independent external power supply wiring connection?

A: No. The unit draws its operating power directly from the internal 24 VDC rails of the CEX backplane bus, drawing a typical current of 100 mA.

Q: Is hot-swapping supported for the CI851K01 module during active system operation?

A: Yes. The hardware design supports live hot-swapping on the TP851 baseplate, permitting online module replacement without requiring a controller shutdown or system power cycle.

Field Installation Guidelines

Mount the TP851 baseplate firmly onto standard 35 mm DIN rails inside the system cabinet, ensuring the integrated grounding clip establishes low-impedance contact with the mounting rail. Insert the CI851 module vertically into the baseplate connectors until the mechanical locking latches snap into place. Leave at least 50 mm of vertical clearance above and below the module assembly to facilitate thermal convection within the maximum operating limit of +55 deg C.

Connect the PROFIBUS-DP network cable to the 9-pin D-sub female connector using standard shielded twisted-pair cable designed for PROFIBUS networks. Terminate cable shields securely at both ends using EMC-compliant metal clamping brackets to suppress high-frequency electromagnetic interference. Route signal cables away from high-voltage power lines and variable frequency drives.
