ABB CI867K01 3BSE043660R1 PROFIBUS DP Communication Interface

Description

1. Core Overview & System Context

2. Key Features & Functions

• PROFIBUS DP-V1 Slave:​ Implements the full PROFIBUS DP-V1 protocol, supporting cyclic data exchange​ (for process data) and acyclic services​ (for parameterization, diagnostics, and alarms).
• S800 I/O Controller:​ Acts as the local controller for an S800 I/O station. It manages the data exchange with the individual I/O modules (like DI, DO, AI, AO cards) installed in the same local rack via a high-speed internal bus.
• Modular Configuration:​ The specific I/O modules connected to it define its process image​ (the mapping of input and output data words on the PROFIBUS). This configuration is set in engineering software.
• Extensive Diagnostics:​ Provides detailed diagnostic information accessible both locally (via LEDs) and over the PROFIBUS network, including module failures, communication errors, and field-side faults.
• Integrated Web Server (likely):​ Many CI867 variants include a built-in web server for configuration, monitoring, and diagnostics via a standard web browser.

3. Technical Specifications

• Communication Interface:
  • Protocol:​ PROFIBUS DP-V1 (EN 50170).
  • Connector:​ 9-pin D-sub female (RS-485).
  • Baud Rate:​ Auto-detect or configurable from 9.6 kbps to 12 Mbps.
  • Address:​ Set via DIP switches or software (typical range 1-125).
• S800 I/O Connection:​ Interfaces with S800 I/O modules via a high-speed parallel backplane bus within the S800 station.
• Power Supply:​ Powered from the S800 station’s internal 24V DC bus.
• Status Indicators:​ LEDs for power, PROFIBUS status (RUN/BUSF), and module status.
• Configuration:​ Configured using ABB’s Control Builder​ or Automation Builder​ engineering tools. The configuration defines the I/O module layout and maps them to PROFIBUS addresses.

4. System Integration & Architecture

• Role in Network:​ It is a slave station​ on a PROFIBUS DP​ segment.
• Physical Setup:
  1. The CI867K01 is mounted in an S800 station​ (e.g., using a DIN-rail mounting unit).
  2. Various S800 I/O modules (e.g., DI810, DO810, AI810, AO810) are installed to its left and right.
  3. A PROFIBUS DP cable connects its D-sub port to the network.
• Data Flow:
  1. Field signals (e.g., sensor on/off) are read by an S800 Digital Input (DI)​ module.
  2. The CI867K01 collects this data from all I/O modules in its station.
  3. The CI867K01 packs this data into its assigned input image​ area in the PROFIBUS DP telegram.
  4. The PROFIBUS Master​ (e.g., a PLC CPU) cyclically reads this input image.
  5. Conversely, the master writes data to the CI867’s output image, which the CI867 unpacks and sends to the appropriate Digital Output (DO)​ or Analog Output (AO)​ modules to actuate field devices.
• Engineering:​ The entire S800 station’s hardware configuration is created in ABB’s engineering software and downloaded to the CI867’s non-volatile memory.

5. Typical Applications

• Factory Automation:​ Connecting remote sensor/actuator clusters to a central Siemens, ABB, or other PROFIBUS master PLC.
• Process Automation:​ As part of a DCS (like ABB’s 800xA) where remote process I/O needs to be connected via PROFIBUS.
• Hybrid Systems:​ Integrating ABB S800 I/O into a third-party control system that uses PROFIBUS DP as its fieldbus.
