Installation and Commissioning Manual
• SPA time synchronization
SPA-ZC 402 has three different modes of the IED time synchronization. The
mode is selected from the logical device object describing the IED, for example
LD1.
• Enabled
This is the default operation mode. When the operation is selected, you can
synchronize SPA-ZC 402 with SNTP as it is defined in the IEC 61850-8-1
standard and SPA-ZC 402 is also synchronizing IED over SPA.
• Disabled
In this mode, you can only synchronize SPA-ZC 402 with SNTP and IED has a
different source of time synchronization.
• Read from device if supported
When this operation mode is selected, the time for SPA-ZC 402 is read from IED
over SPA. SNTP is not in use.
• SPA time synchronization parameter
If you are using the Read from device if supported mode, the parameter describes
the SPA parameter which SPA-ZC 402 uses when reading the time from the IED.
The default parameter is D, as it is defined in the description of the SPA
communication standard.
