ABB 3BHB003688R0101
Quick Identification Summary
Manufacturer: ABB
Product Type: CI854A - PROFIBUS DP/V1 Master Interface Module
Order Number: 3BHB003688R0101
Function: This module allows an AC 800M controller to act as a Master on a PROFIBUS DP and PROFIBUS PA network.

Detailed Technical Parameters
1. Primary Function & Communication
Interface Type: PROFIBUS (Process Field Bus)
Protocols Supported: PROFIBUS DP (Decentralized Peripherals) and PROFIBUS PA (Process Automation) via a segment coupler.
Role: Master (Class 1)
Standard: Fully compliant with EN 50170 Vol. 2 / IEC 61158 / IEC 61784-1 (PROFIBUS DP).
Data Transfer Rate: Automatically detects and configures baud rates from 9.6 kbit/s up to 12 Mbit/s.
2. Physical & Electrical Specifications
Connector: 1 x 9-pin D-sub female connector (following the standard PROFIBUS pinout).
Isolation: Galvanic isolation between the module's internal electronics and the PROFIBUS network.
Termination: Requires an external bus terminator (usually switched on the connector or a separate plug) to be enabled at both ends of the PROFIBUS cable segment.
3. Performance & Capacity
Number of Slaves: Supports up to 96 slave devices on the network.
I/O Capacity: Can handle up to 1440 bytes of input data and 1440 bytes of output data per scan cycle.
Diagnostics: Extensive diagnostic capabilities for the module itself and the connected slaves, accessible through the controller's engineering tool (Control Builder).
4. Integration & Software
Compatible Controller: Designed for use in the AC 800M High Performance (PM856, PM860, etc.) and Compact Performance (PM851) controller racks.
Required Software: Configuration and programming are done using ABB's Control Builder M (often referred to as CBM) engineering tool.
GSD Files: Uses standard PROFIBUS Generic Station Description (GSD) files to integrate and configure slave devices from any manufacturer.
5. Mechanical & Environmental
Module Type: Single-width, hot-swappable module (when used in a supported redundant system configuration).
Operating Temperature: 0 to +60 °C (32 to 140 °F)
Storage Temperature: -40 to +70 °C (-40 to 158 °F)
Relative Humidity: 5 - 95% (non-condensing)
6. LEDs (Front Panel Indicators)
The module features status LEDs that provide critical operational information:
RUN (Green): Indicates the module is operating correctly.
ERR (Red): Indicates a hardware or firmware error.
COM (Yellow): Flashes during data communication on the PROFIBUS network.
MS (Yellow): Indicates the module is the active master in a redundant system setup.
