Description
The node guarding telegram monitors the connection between master and slave.
Under index 100C
h
”Guard time”, you can enter a time, under index 100D
h
”Life time
factor”, you can enter a factor. The multiplication of both indices results in the monitoring
time within which the master must send a node guarding telegram to the slave. If one of
the two indices is set to zero, the monitoring time is also zero, and thus deactivated. The
slave sends a telegram with its current status to the master.
With event-controlled process data transfer, node guarding ensures the cyclic monitoring
of the controller.
ƒ
The master starts node guarding by sending the node guarding telegram.
ƒ
Unless the slave (controller) receives a telegram within the monitoring time, the
node guarding event is activated. The controller switches to the status set under
6007
h
.
ƒ
A reset is carried out by a status change to Operational.
