Functional principle

Each time the MOVI‑C^® CONTROLLER is restarted (24 V supply is switched on), the IEC program checks in the boot application whether the data of devices connected via system bus are still up to date. For this purpose, the system checks by means of the device name (LogicalDevice) whether an inverter data set for this device name exists on the SD memory. The bus address of the connected device is used to check whether this inverter data set differs from the current inverter data set of the device. If it differs, the inverter data set as well as the device name are restored by means of the axis replacement function of the MOVI‑C^® CONTROLLER.

Observe the following notes:

• The names of the devices (LogicalDevices) in the boot application must correspond with the names of the devices in the saved configuration data. If names are changed later only in the MOVISUITE^® project or in the IEC Editor, then the axis data sets cannot be restored automatically via the MOVI‑C^® CONTROLLER.
• When changes are made to the axis parameters, the configuration data have to be updated. Else the values saved last will be restored at the next restart due to the axis replacement function.
• When changes are made to the safety parameters, the configuration data have to be updated. Older data sets cannot be restored.
