1. An activation system for at least one receiving device that is redundantly activatable via a first communication network and via at least one second communication network, the activation system comprising:
at least three transmitting modules including a first transmitting module, a second transmitting module, and a third transmitting module, each of the transmitting modules being a hardware transmission device that is configured to generate messages for the receiving device and to transmit the messages to the receiving device via at least one of the communication networks, at least one transmitting module of the transmitting modules being connectable to both the first and the second communication networks, and the transmitting modules being coordinated at least one of (a) with one another and (b) with the receiving device in such a way that messages from one of the transmitting modules are to be at least one of (a) transmitted via a communication network of the first and second communication networks and (b) processed by the receiving device with priority over messages from another of the transmitting modules;
wherein:
the first transmitting module of the transmitting modules is assigned a role of activating the receiving device during normal operation of the activation system;
the second transmitting module of the transmitting modules is assigned a role of activating the receiving device in the event of an error that deviates from normal operation, when the first transmitting module is unavailable;
the third transmitting module is provided as an additional fallback level for the second transmitting module and is connectable only to the second communication network; and
the first, second, and third transmitting modules are coordinated with one another in such a way that messages sent via the second communication network:
have highest priority when they originate from the first transmitting module;
have medium priority when they originate from the second transmitting module; and
have lowest priority when they originate from the third transmitting module.
