Siemens 6SE6400-1PB00-0AA0 Overview

MICROMASTER 4 PROFIBUS MODULE 6SE6400-1PB00-0AA0 Technical Description


The MICROMASTER 4 PROFIBUS module, model number 6SE6400-1PB00-0AA0, is a specialized communication board designed to establish a PROFIBUS-DP link between the MICROMASTER 4 range of drives and higher-level automation systems.

Key Features

  • Contact Connector: This module houses a single contact connector meant for the control unit, ensuring a secure connection.
  • PROFIBUS Address Switch: A dedicated switch allows users to set the PROFIBUS address for the module, ensuring correct network identification.
  • Operating Status Displays: There are two distinct displays available:
  • One display indicates the operational status of the PROFIBUS board.
  • Another provides the operational status for the MICROMASTER 4.
  • PROFIBUS Interface: A specialized interface is integrated, which is specifically designed for PROFIBUS communication.
  • Local 24 V Connection: The board contains a local 24V connection, with Terminal 1 designated for +24V and Terminal 2 for 0V.
  • Latching Mechanism & Guide: The module features a latching mechanism, ensuring it remains securely in place. A guide is also provided for accurate placement and connection.

Note: Component 6 is reserved for Siemens internal use only.


PROFIBUS stands as an internationally recognized, open field bus standard, finding extensive application in production and process automation domains. A key feature of PROFIBUS is its brand-neutrality and open nature, guaranteed by its adherence to the international standard, IEC 61158.

Within the PROFIBUS ecosystem, the PROFIBUS-DP communication profile is optimized for rapid, time-sensitive data transmission at the field level using cost-effective connections. It emerges as an ideal replacement for the traditional 24 V parallel signal transmission systems in manufacturing and the 4..20 mA signal transmission systems in process automation.

A distinctive feature of PROFIBUS is its multi-master system architecture. In this setup, multiple automation, engineering, or visualization systems can operate in harmony with the related distributed field devices.

Regarding device roles:

  • Master Devices: These devices regulate data traffic on the bus and are termed as "active" nodes. Masters can transmit messages without an external request if they possess bus access authorization (token). Masters fall into two categories:
  • Class 1 Master: Central automation stations such as SIMATIC S5, S7, and SIMADYN D. They interact with slaves in predefined message cycles.
  • Class 2 Master: Systems for programming, configuring, or operator control and monitoring. They play a crucial role in configuring or monitoring a plant during operation.
  • Slave Devices: These devices, which include the MICROMASTER 4 drives, I/O devices, and valves, are known as "passive" nodes. They never obtain bus access authorization. Instead, they respond to received messages or send information to a master only when prompted.

Frequently Asked Questions

Q1: Can I use the MICROMASTER 4 PROFIBUS module with non-Siemens automation systems?

A1: Yes, the module is based on the PROFIBUS international standard (IEC 61158), which ensures brand neutrality. This means it is designed to work with any system that adheres to the PROFIBUS protocol, regardless of the manufacturer.

Q2: How do I set the PROFIBUS address on the module?

A2: The module comes with a dedicated PROFIBUS address switch. By adjusting this switch, you can set the desired address, ensuring the module's correct identification on the network.

Q3: What's the purpose of the "Component 6" mentioned in the technical description?

A3: Component 6 is reserved for Siemens' internal use. It's not intended for end-users or system integrators and therefore doesn't affect the module's functionality or integration in typical use cases.

Q4: I'm experiencing communication issues. How can I verify the operational status of the PROFIBUS board?

A4: The module has a specific display that indicates the operational status of the PROFIBUS board. By monitoring this, you can get insights into the board's current state and troubleshoot if necessary.

Q5: Can the MICROMASTER 4 PROFIBUS module function as both a master and a slave in the PROFIBUS network?

A5: No, the MICROMASTER 4, when equipped with this module, acts as a slave device in the PROFIBUS network. It responds to received messages and can send information back to a master device when prompted, but it doesn't initiate communication or control data traffic on the bus.
