8.7 Node guarding
In case of cyclic node monitoring (Node Guarding), the CAN master regularly enquired 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 activated (fault message "Err
NodeGuard").
Settings
In order that the device takes over the function of the "Node Guarding Slave", make the
following settings:
1. Set C0352 = 2.
(The device is configured as "Node Guarding Slave".)
2. Set the monitoring time (Node Guard Time) for the reception of the status enquiry
by the master in C0383.
3. Set the factor (Node Life Time Factor) for the monitoring time in C0383.
Node Life Time
+ Node Guard Time (C0382) @ Node Life Time Factor (C0383)
4. Set the response to a "Life Guarding Event" via C0384.
