Installation and Commissioning Manual
SPA-ZC 402 has to know the SPA password to enable the control service with
the connected IED. This value is written to the SPA parameter 0V160. The SPA
password has to be the same as defined in IED MMI.
Bit rate
*
The default value of the communication bit rate in the internal link between the
IED and SPA-ZC 402 is 9600. Other possible values are 1200, 2400, 4800,
19200 and 38400 bits/s. Used value has to be same as the configured value in
IED.
REF 541/3/5 3.5 has support for GOOSE horizontal communication. When
protocol 2 mode is adjusted to the IEC 61850 mode, the serial port speed is set to
38400 bits/s. In this mode the special SPA for horizontal communication is used
and it allows to use GOOSE.
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 and the IED gets time synchronization
from another source.
SPA time synchronization parameter
*
The parameter describes the SPA parameter which SPA-ZC 402 uses when
reading the time from the IED. Parameter is used when the previous parameter
defines that the time source is IED. IED gets the time from external source.
Event poll
*
If the parameter is disabled, SPA-ZC 402 does not poll events from IED and the
IEC 61850 events are based on a continuous data poll. This feature could be used
in systems where, for example the other REF 543 port is already used for the
SPA communication. By default, event polls are used.
If the event polling is disabled, the timestamp accuracy depends on the
IED configuration and the SPA bus speed.
