Abstract
A method for automatically updating an existing firmware file stored in a memory of an intelligent electronic device (IED) communicatively coupled to a network in a monitoring system. The IED downloads from a remote server to the IED an update file that includes a version of a firmware file and a filename of the firmware file. The IED determines whether the firmware version specified in the update file is updated compared to a version of the existing firmware file. If the firmware version in the update file is greater than the existing version, the IED communicates to the remote server an instruction to download to the IED the updated firmware file specified in the update file. The IED receives from the remote server the updated firmware file. If a criterion is satisfied, the IED automatically updates the firmware file stored in its memory with the updated firmware file.
