Siemens 6SE7090-0XX84-0FF0 Communication Module

Key Parameters and Features

Core Features & Advantages

• PROFIBUS DP Connectivity for MASTERDRIVES: The module's primary function is to add PROFIBUS DP network capability to the SIMOVERT MASTERDRIVES Motion Control platform. This enables the drive to communicate with a PROFIBUS master (such as a SIMATIC S7 PLC), transmitting control commands and receiving status feedback in a deterministic, high-speed manner .

• Essential for Legacy System Integration: Despite being discontinued for over two decades, the CBP module remains critical for maintaining existing SIMOVERT MASTERDRIVES installations. It allows legacy drive systems to remain integrated with plant-wide automation networks, extending their operational life without requiring full system replacement .

• Structured Installation and Compatibility: As a plug-in option board, the CBP module is designed for easy integration into the MASTERDRIVES electronics box. It works alongside the ADB (Adapter Board) carrier for physical installation . Users should note that the CBP module (0FF0) is distinct from its successor, the CBP2 module (0FF5), though they serve similar functions .

Typical Applications

The 6SE7090-0XX84-0FF0 is used as a communication component in SIMOVERT MASTERDRIVES systems across various industrial applications:

• Legacy Drive Maintenance: Maintaining existing MASTERDRIVES installations where PROFIBUS DP connectivity is required 

• Industrial Automation: Drive systems in manufacturing and process industries requiring integration with S7 PLC networks

• System Upgrades: Allowing older drive platforms to participate in modern automation architectures without complete replacement

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 6SE7090-0XX84-0FF0?

A: It is a PROFIBUS DP communication module (CBP) for SIMOVERT MASTERDRIVES Motion Control systems. Its role is to provide the communication interface between the drive and a PROFIBUS network for data exchange with PLCs or DCS systems .

Q2: Is the 6SE7090-0XX84-0FF0 still in production?

A: No. This module has been discontinued by Siemens since February 19, 2000 . It is available only through surplus, refurbished, or new-old-stock channels from third-party suppliers.

Q3: What is the difference between 6SE7090-0XX84-0FF0 and 6SE7090-0XX84-0FF5?

A: The 0FF0 is the original CBP (Communication Board PROFIBUS) module. The 0FF5 is the CBP2 module, a later, more capable version. Both are used for PROFIBUS communication with MASTERDRIVES systems, but they are different hardware revisions . The CBP2 (0FF5) is documented as the successor with enhanced capabilities.

Q4: What are the physical characteristics of this module?

A: The module weighs approximately 0.06 to 0.10 kg and measures approximately 8.50 x 10.00 x 2.00 cm. It was manufactured in Germany and is a compact plug-in option board .

Q5: What GSD file is required for this module?

A: The GSD file for the MASTERDRIVES CBP is siem8045.gsd (version 1.2 / 1999). This file is required for configuring the module as a PROFIBUS slave in the PLC's hardware configuration .

Q6: Can I use this module with a SIMATIC S7-300/400 PLC?

A: Yes. The module is designed to function as a PROFIBUS DP slave. You will need the appropriate GSD file installed in your PLC programming software to configure the module in the network .

Q7: What are the common issues when commissioning this module?

A: A common issue is a "DP Error" when the drive does not appear in the PROFIBUS catalogue. This typically indicates the correct GSD file is not installed or the module configuration does not match the network settings. Ensure the GSD file (siem8045.gsd) is properly loaded and the PROFIBUS address is correctly configured .

Choosing the Right Model

• For existing MASTERDRIVES systems requiring PROFIBUS: The 6SE7090-0XX84-0FF0 (CBP) is the original module for this application. However, if the newer 0FF5 (CBP2) is available, it offers enhanced capabilities and may be preferable for replacements .

• For encoder evaluation: Consider the SBM (0FD0) or SBM2 (0FE0) modules for resolver/encoder feedback applications .

• For complete system maintenance: Ensure you have the correct GSD file (siem8045.gsd) for PROFIBUS network configuration .
