Siemens 3UF7900-0AA01-0 Specs: SIMOCODE pro C Memory Module Guide
The Siemens 3UF7900-0AA01-0 is a titanium-gray memory module designed to store and transfer parameter settings for SIMOCODE pro C motor management systems without requiring a PC or programming device (PG). It is particularly useful when backing up a configuration or transferring parameters during a compatible device replacement. Before using it, engineers must confirm the SIMOCODE basic unit generation and product version because memory module compatibility differs across the SIMOCODE pro family.

What Does the SIMOCODE pro C Memory Module Do?
SIMOCODE pro C is a motor management system that combines motor protection, monitoring, and control functions. Its parameter settings define how the configured system behaves, including application-specific protection and control functions.
The 3UF7900-0AA01-0 memory module provides a way to save and transfer the relevant parameterization without relying on a connected PC/PG during the transfer process. This can simplify maintenance when a compatible SIMOCODE device needs to be replaced.
Its practical value is configuration continuity. Instead of recreating settings manually, maintenance personnel can use the supported memory-module procedure to transfer stored parameters to a compatible device.
When Is This Memory Module Useful?
Replacing a SIMOCODE pro C basic unit
When a basic unit needs replacement, restoring the previous configuration is an important commissioning task. A compatible memory module can help transfer saved parameters and reduce manual re-entry.
However, the module does not establish that every replacement device is electrically or functionally interchangeable. The replacement basic unit, hardware version, connected modules, and application configuration must still be checked.
Backing up motor management settings
Maintaining a copy of the parameterization can help support planned maintenance and recovery after a device failure. The backup should be managed as part of the plant’s maintenance documentation rather than treated as a substitute for a complete project record.
Reducing dependence on a programming device
The memory module is designed for parameterization without a PC/PG. This can be useful during field maintenance when a programming workstation is not immediately available, provided the basic unit supports the module and the official transfer procedure is followed.
3UF7900-0AA01-0 Compatibility: What Must Be Checked?
The most important selection issue is compatibility across SIMOCODE product families and product versions. Siemens documentation distinguishes the 3UF7900 and 3UF7901 memory module families.
| SIMOCODE system | Compatibility guidance |
|---|---|
| SIMOCODE pro C | 3UF7900 memory modules are supported. |
| SIMOCODE pro V PB, product versions up to E08 | 3UF7900 memory modules are supported. |
| SIMOCODE pro V PB, product version E09 and later | Check the applicable manual; Siemens documents support for the newer memory-module options. |
| SIMOCODE pro S and pro V MR | Compatibility depends on the documented product version and system configuration. |
| SIMOCODE pro V PN and pro V EIP | Use the specified 3UF7901 memory module family; 3UF7900 is not supported for these basic units. |
These distinctions are important because a module that works with one SIMOCODE basic unit may not work with another. Before ordering, check the exact basic-unit designation, product version, and the compatibility table in the Siemens SIMOCODE pro system manual.
Memory Module vs. Initialization Module
A memory module and an initialization module serve related but different maintenance purposes. A memory module supports parameter backup and transfer during compatible replacement procedures. An initialization module is intended for storing and initializing device parameters and addressing in motor control centers, where supported.
Do not assume the two accessories are interchangeable. Siemens documents initialization-module support separately, including product-version requirements for specific basic units. If a permanent configuration-transfer arrangement is needed, verify whether the intended SIMOCODE system supports the initialization module rather than choosing by appearance alone.
Replacement and Procurement Checklist
Before purchasing 3UF7900-0AA01-0, verify the following details:
- Identify the basic unit: Record the complete SIMOCODE model number and product version.
- Confirm the system family: Establish whether the installation uses SIMOCODE pro C, pro V PB, pro V PN, pro V EIP, or another variant.
- Check module compatibility: Compare the basic unit and memory module against Siemens’ compatibility documentation.
- Confirm the transfer procedure: Follow the applicable Siemens instructions for storing, loading, and validating parameters.
- Keep a separate configuration record: Retain relevant project files and commissioning documentation where available.
For related motor management components, see the Siemens 3UF7010-1AU00-0 SIMOCODE pro V basic unit guide and the 3UF7101-1AA00-0 current measuring module guide. These articles cover other SIMOCODE components; neither should be treated as a replacement for the memory module.
You can also browse the Siesource industrial automation catalogue for related components. When enquiring about this memory module, provide the complete part number and the installed SIMOCODE basic-unit model and product version so compatibility can be checked before purchase.
Frequently Asked Questions
What is Siemens 3UF7900-0AA01-0 used for?
It is a titanium-gray memory module used to store and transfer SIMOCODE pro C parameter settings without a PC/PG, subject to system compatibility.
Can 3UF7900-0AA01-0 be used with every SIMOCODE pro basic unit?
No. Compatibility depends on the SIMOCODE family and product version. Siemens specifies the 3UF7901 family for SIMOCODE pro V PN and pro V EIP basic units.
Does the memory module replace the SIMOCODE basic unit?
No. It is an accessory for parameter backup and transfer, not a motor management controller or protection device.
What should be checked before ordering this module?
Confirm the complete basic-unit model, product version, SIMOCODE family, and the manufacturer’s compatibility and transfer instructions.
Conclusion
The Siemens 3UF7900-0AA01-0 is a titanium-gray memory module designed to simplify parameter backup and transfer for compatible SIMOCODE pro C systems. Its value lies in helping preserve configuration settings during maintenance, but compatibility must be checked carefully across SIMOCODE families and product versions. Confirm the installed basic unit and follow Siemens’ documented transfer procedure before using the module in a replacement project.
