Description

ABB CI840

Technical Specifications:

  • Network Type: Industrial Ethernet (Redundant).
  • System: ABB S800 I/O and AC 800M.
  • Protocols: MODBUS/TCP, ABB Redundant Protocol.
  • Physical Interface: Dual RJ45 Ethernet ports.

Functional Features:

  • Redundant Ethernet: Dual ports for network redundancy and seamless failover.
  • High-Speed Data Transfer: Gigabit-capable Ethernet for high-bandwidth applications.
  • Protocol Flexibility: Supports multiple industrial Ethernet protocols.

Application Scenarios:

  • High-bandwidth I/O stations requiring fast data exchange.
  • Integration of S800 I/O into plant-wide Ethernet networks.
  • Redundant control system architectures.

Performance Parameters:

  • Fast Failover: Sub-millisecond switchover in redundant Ethernet configurations.
  • High Throughput: Supports large data volumes for advanced I/O modules.

Material Composition & Structural Characteristics:

  • Enclosure: Standard S800 I/O module.
  • Connectors: Dual RJ45 Ethernet ports with link/activity LEDs.

Working Principle:
The CI840 manages the S800 I/O bus and provides a redundant Ethernet link to the AC 800M controller or higher-level systems. It continuously monitors both Ethernet links and automatically switches to the backup link if a failure is detected, ensuring uninterrupted communication.

Installation Requirements:

  • Network Cabling: Use CAT5e or higher shielded Ethernet cables.
  • Redundant Configuration: Connect both RJ45 ports to separate network switches for true redundancy.
  • IP Configuration: Assign unique IP addresses and configure redundancy parameters in Control Builder.

Usage Precautions:

  • Network Topology: Ensure the network topology supports the configured redundancy protocol.
  • Switch Configuration: Configure network switches to support the required Ethernet protocols and redundancy features.
