System Time tab
The System Time tab contains information about the C300 Controller’s time source and
synchronization with that time source. The “System Time” and “System Time
Synchronization Status” subgroups on this tab provide current controller system time and
indicate the time source with which it is synchronized and status of synchronization with
that source. “SNTP Status” and “GPS Status” subgroups provide meaningful statistics
related to time synchronization with SNTP servers and GPS sources, along with their
status. The following table summarizes the parameter data you can monitor on the
System Time tab of the configuration form for the selected C300 block.
