SDO 100C: Guard Time
The guard time (UINT) multiplied by the life time factor (SINT) results in the life guarding time.
Life Guarding Time [ms] = Guard Time [ms] × Life Time Factor
During the Life Guarding Time, the master must send at least one node guarding
message to the slave. When the life guarding time is exceeded (life guarding error), the gate-
way reports a cable break error and sets all network process data to 0; the LED NS starts to
flash red.
In the slave, life guarding is activated by the first node guarding message when the life guar-
ding time has not been set to 0. When the guard time or the life time factor are set to 0 after
activating life guarding, life guarding will be deactivated.

SDO 100D: Life Time Factor
SDO 100D contains the Life Time Factor (SINT). See SDO 100C.
NOTICE
The Life Time Factor must either be = 0 (deactivated) or V 1.5.
SDO 1016: Consumer Heartbeat Time
The gateway is configured as a heartbeat consumer when SDO 1016 contains a value greater
than
0 for the consumer heartbeat time. The consumer heartbeat time is given in ms.
The NMT master must send at least one node guarding message to the slave within this time.
When the consumer heartbeat time is exceeded (life guarding error), the gateway reports a
cable break error and sets all network process data to 0; the LED NS starts to flash red.
SDO 1017: Producer Heartbeat Time
The gateway can also act as a heartbeat producer, i.e. send a heartbeat signal.
This allows another device to detect whether the heartbeat producer (i.e. the gateway) is still
functioning correctly.
The producer heartbeat time is given in ms. For internal processing it is rounded up
to the next higher multiple of 4. If the heartbeat time is set to 0, the heartbeat signal is deacti-
vated.
The heartbeat signal consists of a cyclic CAN message with the identifier 700h + device
address.
NOTICE It is not possible to use heartbeat signals and life guarding messages simultaneously, as both
functions make use of the same CAN identifier.
