Using a Device with an Earlier Firmware Version
When logging in or downloading a project with EcoStruxure Machine Expert, you may encounter a compatibility concern with your controller firmware:
In this message, the selected version is the device description version of the active application; the online version is the firmware version of the controller.
In this case, updating the device firmware is necessary. Device firmware is provided with the EcoStruxure Machine Expert installation (managed by the Machine Expert Installer) or can be found on the Schneider Electric website.
Refer to the Settings Helping to Preserve Compatibility to understand how to avoid this situation in future versions of EcoStruxure Machine Expert.
Refer to the chapter Compatibility of Controller and Device Description Versions to understand the compatibility rules (which device version can be downloaded to which controller firmware version).
