8.6 Node guarding
The "Node Guarding" function is implemented as of operating system V3.0.
In case of cyclic node monitoring (Node Guarding) the CAN master regularly enquires the
states of the slaves participating in the monitoring process.
ƒ The master starts the node guarding by sending the node guarding telegram.
ƒ If the slave does not receive a node guarding telegram within the monitoring time
(Node Life Time), the "Life Guarding Event" is enabled (fault message "NodeGuard
Trp/Msg/Wrn").
Settings
In order that the power supply module takes over the function of the
"Node Guarding Slave", make the following settings:
1. Set C0352 = 2.
(The power supply module is configured as "Node Guarding Slave".)
2. Set the time interval of the status enquiry by the master (Node Guard Time) via
C0382.
3. Set the factor for the monitoring time (Node Life Time Factor) via C0383.
Node Life Time
+ Node Guard Time (C0382) @ Node Life Time Factor (C0383)
4. Set the response to a "Life Guarding Event" via C0384.
