10.3.3 Commissioning example
Task
An inverter configured as heartbeat consumer (node 2) is to monitor another inverter (heartbeat
producer; node 1).
• The heartbeat producer is to transmit a heartbeat telegram to the heartbeat consumer every
10 ms.
• The heartbeat consumer monitors the heartbeat telegram for arrival. A response is to be
activated in the event of an error.
Parameterising the heartbeat producer (node 1)
1. Set the heartbeat producer time (C00381
) to 10 ms.
Parameterising the heartbeat consumer (node 2)
1. Set the CAN node address of the producer in C00385/1
.
2. Set the heartbeat consumer time in C00386/1
.
• Note: The heartbeat consumer time must be greater than the heartbeat producer time of the
node to be monitored set in C00381
.
3. Set the desired response in C00592/5
which is to be activated if a heartbeat event in the
consumer occurs.
Tip!
C00347/1...n
displays the heartbeat status of the nodes monitored.
Heartbeat telegram
• The heartbeat telegram from the producer has the following identifier:
Identifier (COB-ID)= 1792 + producer node address = 1792+1= 1793=0x701
