Safety Guidelines
The use of these functions should only be used by qualified users.

Override default limit values for synchronization
For standard operation this function is disabled and should only be used by qualified users.
Lambda (λ)
For observance of specified accuracy of Module 8029NTC, it uses only accurate NTP server
for synchronisation which have an accuracy value for lambda better 20ms.
In case it is required that Module 8029NTC should be synchronized on a more inaccurate NTP
server the threshold accuracy value for lambda can be adjusted by this function.
The actually calculated lambda value is shown in the General tab.
Therefore, the function "
Override default limit values for synchronisation
" needs to be
activated and to configure the required accuracy value for lambda (1-999ms).
When using this function, the specified accuracy of Module 8029NTC and
thus the accuracy of devices and components synchronized by the
module may be worsened.
Minimum Accuracy
Only with the accuracy status
accuracy = high
Module 8029NTC synchronizes.
This function can be used for NTP server not being able to synchronize Module 8029NTC with
the required accuracy. It allows the adjustment of the accuracy value (
accuracy = high
/
medium
/
low
) and the accuracy of the connected devices and components for the
synchronization.
Modification of values do not cause an immediate effect when clicking on
the apply symbol. In addition, the NTP service
must
be restarted (see
Chapter 5.3.6.4
).
