Could not find the exact order number?
Send us the full code of the original module, for example 6ES7…, or a photo of the front and nameplate. We will check a compatible replacement, the availability of an original or refurbished part, and, where applicable, the possibility of repair.
How to choose the correct SIMATIC S7 module replacement
- Copy the full code.
A difference of a single character in the order number may indicate a different electrical or functional version. - Compare the parameters.
Check DI/DO/AI/AO, the number of channels, voltage, current, resolution, output type and connector wiring. - Check the configuration.
A direct replacement usually requires no program change, but always check the hardware configuration and diagnostic functions.
Frequently asked questions about compatible S7-300 and S7-200 replacements
Is SOFTLINK an original SIEMENS module?
No. SOFTLINK is an alternative manufacturer. Selected modules are intended as compatible replacements for specific SIEMENS or VIPA order numbers. Suitability must be assessed from the complete designation and technical parameters.
Does the PLC program need to be changed when replacing the module?
Usually not for a direct replacement of the same type. However, it depends on the hardware configuration, addressing, diagnostics, firmware used and the specific application. We recommend verifying compatibility before installation.
Can the replacement also be used instead of a VIPA module?
For items where the table lists a corresponding VIPA code, the replacement is also intended for that type. Always compare the number of channels, electrical parameters, connector and wiring.
What if my module is not listed in the table?
FOXON can check the availability of a compatible replacement, a new original, refurbished or discontinued SIEMENS module. Professional repair of the original part is also available for selected types.
SIEMENS, SIMATIC and VIPA are trademarks of their respective owners. The compatible replacements offered are not original Siemens products unless expressly stated otherwise for a particular product. The information in this table is provided as a guide; the current technical parameters of the specific product and verification of suitability for the application are decisive.
