9.8.2.2 Parameter setting
Short overview of the parameters for the "Heartbeat" monitoring function:
Heartbeat producer time
Time interval for the transmission of the heartbeat telegram to the consumer(s).
• Parameterisable in C381
or via object I-1017. The parameterised time is rounded down to an in-
teger multiple of 5 ms.
• The heartbeat telegram is sent automatically as soon as a time > 0 ms is set.
Heartbeat consumer time
Monitoring time for the nodes (producers) to be monitored.
• Parameterisable in C386/1...n
or via object I-1016.
• The parameterised time is rounded down to an integer multiple of 5 ms and must have a greater
value than the heartbeat producer time of the node to be monitored.
• The maximum number of the nodes to be monitored depends on the device version:
• "BaseLine C": 1 Heartbeat Producer can be monitored.
• "StateLine C": Up to 7 Heartbeat Producers can be monitored.
• "HighLine C": Up to 15 Heartbeat Producers can be monitored.
• "TopLine C": Up to 15 Heartbeat Producers can be monitored.
• The node address(es) of the nodes to be monitored is/are set in C385/1...n
or via object I-1016.
Heartbeat event
The "Heartbeat event" is activated in the consumer if it does not receive any heartbeat telegram
from the producer within the heartbeat consumer time:
• The consumer changes from the "Operational" communication status to the "Pre-Operational"
communication status.
• The NMT master receives an emergency telegram containing emergengy error code 0x8130.
• The response parameterised in C592/5
is activated (Lenze setting: "No response").
