Commissioning example

Task
An 8400 controller (node 2) which is configured as heartbeat consumer is to monitor another 8400

controller (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 activa-

ted in the event of an error.

Parameterising the heartbeat producer (node 1)

1. Set the heartbeat producer time (

C381

) to 10 ms.

Parameterising the heartbeat consumer (node 2)

1. Set the CAN node address of the producer in

C385/1

.

2. Set the heartbeat consumer time in

C386/1

.

• Note: The heartbeat consumer time must be greater than the heartbeat producer time of the

node to be monitored set in

C381

.

3. Set the desired response in

C592/5

which is to be activated should a heartbeat event in the con-

sumer occur.

Tip!
In

C347/1...n

displays the heartbeat status of the monitored nodes.

Heartbeat telegram

• The heartbeat telegram of the producer has the following identifier:

Identifier (COB-ID) = 1792 + producer's node address = 1792 + 1 = 1793 = 0x701

Note!

The heartbeat monitoring will not start until the first heartbeat telegram of a monitored

producer has been received successfully and the "Pre-Operational" NMT status has been

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