ABB CI861K01 3BSE058590R1 Communication Module

The ABB CI861K01, also cataloged as the CI861 Communication Module, operates as a dedicated hardware component for high-speed Variable Information Processor (VIP) protocol execution within ABB AC 800M and AC 800PEC control systems. The assembly interfaces with the controller backplane using the included TP853 baseplate, enabling real-time TCP/IP and UDP/IP network data frames between process controllers, IBA/ARGUS loggers, and Level 2 supervisory architectures.

Hardware Specifications

Backplane Bus Architecture & Deterministic Ethernet Performance

The CI861 module offloads high-frequency VIP communication processing from the main controller CPU, maintaining deterministic message distribution over dual Ethernet ports. High-density CEX-Bus integration allows seamless data polling across connected IBA loggers and U-Gauge hardware without introducing execution latencies into the control loop. Integrated firmware flash compatibility ensures synchronized hardware handshake execution across System 800xA control topologies. Furthermore, hot-swap support allows technicians to replace the module on the TP853 terminal baseplate during live operations while maintaining electrical isolation on the main backplane.

Frequently Asked Questions

Q: Does replacing a CI861 module require powering down the entire AC 800M controller rack?

A: No, the CI861 module supports hot swapping on the TP853 baseplate. Technicians can unlatch and replace the communication interface online without disrupting live backplane power to adjacent I/O units.

Q: What network protocols does the CI861 interface support across its dual Ethernet ports?

A: The module executes TCP/IP- and UDP/IP-based Variable Information Processor (VIP) protocols, providing direct data links between AC 800M/PEC controllers, data loggers, and Level 2 automation platforms.

Q: Is the TP853 baseplate included with the CI861K01 package?

A: Yes, the CI861K01 package contains both the CI861 VIP communication interface card and the 60 mm wide TP853 terminal baseplate.

Field Installation Guidelines

• Baseplate Engagement: Mount the TP853 baseplate on a standard 35 mm DIN rail. Slide the unit laterally along the rail to lock the CEX-Bus backplane connectors prior to tightening mechanical grounding clips.
• Module Seating: Align the CI861 interface guide pins with the TP853 terminal baseplate slots. Push the card firmly into place until the upper and lower locking levers snap shut.
• Ethernet Cable Installation: Connect shielded twisted-pair (STP) Ethernet cables with 8-pin RJ45 connectors to the dual network ports. Route communication cables in dedicated wire channels separated by a minimum of 200 mm from high-voltage AC power wiring.
• Shield Grounding: Connect Ethernet cable braid shields to the cabinet ground bar using low-impedance grounding clamps to prevent high-frequency common-mode noise interference.
