• The parameterised time is rounded down to an integer multiple of 5 ms and must have a greater

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.
