Guard Time
A message will be sent to the CANopen nodes at fixed intervals, with the
interval's length being defined by the "guard time" object. If a node fails to
respond with the specified guard COB-ID, it will be assigned the "Timeout"
status. The number of failed attempts before the CANopen node is catego-
rized as "not OK" is specified by the "life time factor" object (object 100D
hex
).
Guard time = 0: Node guarding disabled.
