If the Nodeguarding option is activated, a message is sent to the module at
the interval specified in milliseconds under Guard Time. If the module does
not respond and the number of attempts (Life Time Factor) has been
reached, the module is regarded as not NOK (defect or not existing).
The status of the module is saved in the system variable of the control
system DB1_NC2SPS_COPMODUL_VORHANDEN_AW (
¶ 240).
For all modules, the standard setting is Guard Time = 500 and Life Time
Factor = 3. This setting means that a failure is detected after 500 ms x 3 =
1.5 s. If no Guard Time and no Life Time Factor are specified (= 0), the module
is not monitored.
Further settings are not required.
A task configuration is only required if system variables of data block_0 are
used (
