The Siemens 6SE7090-0XX84-0FF5 is a PROFIBUS DP communication option module specifically designed for the Siemens SIMOVERT MASTERDRIVES series (VC, MC, and SL models). It enables seamless integration of MASTERDRIVES frequency converters into PROFIBUS DP industrial networks, facilitating data exchange between the drive and upper-level controllers (e.g., SIMATIC S7 PLCs) for remote control and monitoring. Below are its detailed specifications compiled from legacy technical documentation and industrial automation resources:
- Manufacturer: Siemens AG
- Product Series: SIMOVERT MASTERDRIVES (Option Module)
- Product Type: PROFIBUS DP Communication Module
- Status: Discontinued (Obsolete, legacy component for older MASTERDRIVES systems)
- Target Systems: Exclusively compatible with Siemens SIMOVERT MASTERDRIVES VC (Voltage Source Converter), MC (Motion Control), and SL (Single Loop) series converters. Requires pairing with the MASTERDRIVES control unit (e.g., CUVC board 6SE7038-6EK84-1JC2) via its dedicated option slot.
- PROFIBUS DP Compliance:
- Complies with IEC 61158-2 (PROFIBUS DP standard) and EN 50170 (European standard for industrial communication).
- Functions as a PROFIBUS DP Slave device, responding to control commands from a DP Master (e.g., SIMATIC S7-300/400 PLC).
- Data Exchange Capabilities:
- Cyclic Data Exchange: Transmits/receives real-time control signals (e.g., speed reference, start/stop commands) and status data (e.g., motor current, drive running state) with the master controller. Supports up to 32 bytes of input data and 32 bytes of output data (configurable via parameterization software).
- Acyclic Data Exchange: Enables remote parameterization and diagnostics of the MASTERDRIVES converter (e.g., reading/writing drive parameters, fault codes) via the PROFIBUS network, eliminating the need for local operation.
- Communication Performance:
- Baud Rate: Auto-adaptive to the PROFIBUS DP network’s baud rate, supporting speeds from 9.6 kbps to 12 Mbps (matches the master controller’s settings).
- Cycle Time: Dependent on network load and baud rate; typical minimum cycle time for cyclic data is < 1 ms at 12 Mbps (ensures real-time control responsiveness).
- PROFIBUS Address: Configurable via DIP switches on the module (address range: 0-126) for easy identification in the network.
- Network Integration:
- Supports PROFIBUS DP V1 protocol, enabling advanced diagnostics (e.g., detailed fault messages) and acyclic data exchange in addition to basic cyclic control.
- Compatible with Siemens STEP 7 software for network configuration (GSD file:
6SE7090_0XX84_0FF5.GSD required for device integration into the PLC project).
- Diagnostics & Status Monitoring:
- LED Indicators: Provides visual status feedback via two LEDs:
- Green LED: Indicates valid PROFIBUS communication (flashes for data activity, steady for idle).
- Red LED: Signals communication errors (e.g., invalid baud rate, address conflict, or module fault).
- Fault Signaling: Transmits module and drive faults to the PROFIBUS master via acyclic data, enabling centralized troubleshooting of the entire drive system.
- Redundancy Support:
- Optional support for PROFIBUS DP Redundancy (when used with redundant DP Masters, e.g., SIMATIC S7-400H), ensuring uninterrupted communication in critical applications (e.g., power plants, process control).
- Power Supply: Draws power directly from the host MASTERDRIVES converter’s control unit (e.g., CUVC board) via the option slot connector. No external power source is required.
- Input Voltage: 24 V DC ±10% (derived from the converter’s internal control voltage rail).
- Power Consumption: < 2 W (low-power design to avoid overloading the control unit’s power budget).
- Electrical Isolation: Galvanic isolation between the PROFIBUS interface and the converter’s internal circuits (isolation voltage: 500 V AC for 1 minute), preventing electromagnetic interference (EMI) from industrial environments.
- Dimensions: Approx. 60 mm (Width) × 100 mm (Height) × 30 mm (Depth) (compact plug-in form factor to fit the MASTERDRIVES control unit’s option slot).
- Weight: Approximately 0.15 kg.
- Mounting: Plug-in installation into the dedicated communication option slot on the MASTERDRIVES control unit (CUVC/CUMC). Secured via a locking clip to prevent disconnection during vibration.
- Protection Class: IP20 (dust-protected, suitable for indoor industrial environments when installed within the converter’s control cabinet).
- Operating Temperature Range: 0°C to +40°C (matches the host MASTERDRIVES converter’s operating temperature range).
- Storage Temperature Range: -20°C to +70°C.
- Relative Humidity: 5% - 95% (non-condensing).
- Typical Applications: Used in industrial systems requiring centralized control of MASTERDRIVES converters, such as manufacturing lines, conveyor systems, and pump/compressor stations, where PLC-based networked control improves operational efficiency.
- Replacement Options: As an obsolete product, it is replaced by communication modules for Siemens’ modern SINAMICS series converters. For SINAMICS S120, the comparable module is the 6SL3255-0AA00-4BA1 (PROFIBUS DP module), which offers higher communication speeds and compatibility with PROFINET (via additional modules).
- GSD File Availability: The GSD file for network configuration is no longer hosted on Siemens’ official website but may be available through third-party industrial automation resource platforms or legacy software archives.
The 6SE7090-0XX84-0FF5 is no longer manufactured by Siemens. It is primarily available through specialized resellers of refurbished industrial automation parts or surplus stock. Users maintaining older MASTERDRIVES systems should verify compatibility with their converter’s control unit model (e.g., CUVC) and firmware version to ensure proper communication.
