- Lifetime Factor
If the Lifetime factor is multiplied by the Guard time, the result is the
Lifetime for Node Guarding.
Example:
Guard time: 100 ms
Lifetime factor: 3
The Guard time of 100 ms means that the network nodes expect a
Guard Frame from the master every 100 ms. The Lifetime factor
enables a setting to be made in the BL20-CANopen gateway for
how often a Guard Frame from the Master can be missed before an
error condition is recognized.
In this example, the relevant time would be 300 ms. The evaluation
would only become active after the message had been missing for
300 ms.
