Schneider Electric updates the controller frequently providing new features and functions. Therefore, there may be a difference between the version you receive as a new product, the present version being put into stock from the factory, and the version of your EcoStruxure Machine Expert installation.
Controller with an Earlier Firmware Version
You received a controller with a firmware version earlier than the one of the devices in your EcoStruxure Machine Expert project.
In this case, updating the controller firmware is necessary. Controller firmware is provided inside the EcoStruxure Machine Expert installation or can be found on the Schneider Electric website.
If you do not update your controller, you are able to log in to your controller only if the compatibility rule is respected.
Controller with a Later Firmware Version
You may receive a controller with a firmware version later than one of the devices in your EcoStruxure Machine Expert project.
In this case, updating the project is necessary.
Alternatively, consider downgrading the firmware of your controller.
In general, you are able to log in to your controller only if the compatibility rule is respected.
