ABB 500PB101 1MRB178009R0001 1MRB200064/C Communication Module

The ABB 500PB101 (Part Number: 1MRB178009R0001 / 1MRB200064/C) is a dedicated PROFIBUS-DP Communication Module used within the ABB REB500 busbar protection system and the broader Relion or Advant OCS series. 

It serves as the bridge between the protection system's central unit and external fieldbus networks, allowing for the integration of high-speed protection data into substation automation or DCS systems.

Introduction

The 500PB101 is designed to handle high-speed cyclic data exchange (DP-V0) and acyclic services (DP-V1), ensuring that trip signals, status feedbacks, and diagnostic information from the REB500 rack are communicated reliably to a Master station.

 The revision /C typically indicates improved hardware stability and updated onboard firmware for better compatibility with modern PROFIBUS masters.

Technical Parameter Table

Product Advantages and Features

High-Speed Integration: Allows the REB500 system to share real-time protection data with a PLC or DCS at speeds up to 12 Mbps.

Acyclic Data Access: Supports DP-V1 functionality, enabling the retrieval of detailed diagnostic records and disturbance files without interrupting process data.

Hardware Robustness: Built for Sweden-standard industrial environments; the module features high EMC immunity to withstand the electrical noise of HV substations.

Simple Configuration: Easily recognized by ABB configuration tools like PCM600 or HMI500. using standardized GSD files for third-party integration.

Diagnostic LEDs: Front-panel indicators provide immediate status for "Power," "Online," and "Communication Error."

Application Cases

DCS Integration: Connecting a distributed busbar protection system to an ABB 800xA or Freelance DCS via PROFIBUS.

Substation Automation: Relaying breaker status and trip events to a station-level HMI when IEC 61850 is not the primary protocol.

Fault Analysis: Extracting disturbance recorder data from the central unit to a remote engineering workstation.

Redundant Networks: Often used in pairs within a redundant rack to ensure communication remains active if one bus line fails.

Installation and Maintenance

Installation

Termination: Ensure that the PROFIBUS line is properly terminated at both ends of the segment. Use a 9-pin D-sub connector with a built-in termination switch.

Slot Assignment: The module must be plugged into the designated communication slot of the REB500 central unit subrack.

Address Setting: Check if the node address is set via onboard dip-switches or if it is assigned via the software tool before powering the rack.

Maintenance

Connection Check: Periodically inspect the D-sub connector for tightness; vibration in turbine or generator halls can loosen serial cables.

GSD File Management: Ensure you have the correct GSD file version that matches the 1MRB200064/C hardware for your master station configuration.

Firmware Consistency: If replacing an older revision (e.g., /A or /B) with the /C version, verify that the master station configuration does not require an update.

Peer Note: If the "BF" (Bus Fault) LED is solid red, check the Baud Rate settings in your Master station. 

The 500PB101 is usually very reliable, but it is sensitive to reflections on the PROFIBUS line caused by poor termination or low-quality cables.
