Task
An 8400 inverter (node 2) which is configured as heartbeat consumer is to monitor another 8400
inverter (heartbeat producer, node 1).
• The heartbeat producer is to transmit a heartbeat telegram to the heartbeat consumer every

• The heartbeat consumer monitors the heartbeat telegram for arrival. A response is to be
activated in the event of an error.

The boot-up telegram counts as the first heartbeat telegram.
