7.9.10 Guard Time (100C
h
) und Life Time Factor (100D
h
)
The CAN-CBX module supports the node guarding or alternatively the heartbeat function (see page 69).
Note:
By the recommendation of the CiA, the heartbeat-function shall be used
preferentially. Use the node-guarding only for existing systems and not for new
developments!
Guard time and life time factors are evaluated together. Multiplying both values will give you the life
time. The guard time is represented in milliseconds.
