In some cases, it is required to prepare the update and then plan the start for a later time or under some strategic conditions. In this case the software is transferred to the device first. Later (e.g. at the end of the shift or on the weekend) and under specific conditions (e.g. nothing to produce) the update Client can start the update. In this scenario the time and the conditions are known and checked by the update Client, not by the Server, so for the use of the software update options an established Client-Server connection is required. The scheduling is a task of the Client and not described in this specification.
