Software Configuration with the GSDML Composer
5.9.6 Heartbeat/Guarding
Use this page to specify the settings of the
Heartbeat
and
Node Guarding
protocols.
Node Guarding:
Guard Time
The NMT master transmits guarding requests to the slave in this interval.
Lifetime Factor
The
Guard Time
multiplied by this value results in the
Node Lifetime.
This is
the period after which the slave reports an error if there have not been any
guarding requests received.
INFORMATION
Both values
Guard Time
and
Lifetime Factor
must be greater than '0' to keep the Node
Guarding enabled.
Heartbeat:
Heartbeat Producer,
Heartbeat Time
If a value greater than '0' is specified here, this slave is
Heartbeat Producer
and generates Heartbeat messages in the interval specified.
Heartbeat Consumer,
Interval
This value specifies the interval in which the
Producer
(the CANopen-PN
here) expects the Heartbeat messages. ('0' to disable)
This value must be sufficiently greater than the interval of the
Producer
,
because otherwise missing heartbeats might result, only due to the jitter at
transmission/reception.
INFORMATION
It is not possible to use both protocols simultaneously. If both protocols are configured,
the Heartbeat protocol is used.
