1)When the gateway detects a change in this field, it will update the internal date and
time counter to be used when synchronizing the SPA slave device. The time
synchronization is enabled by selecting the option in PCT, for details see
Section 5.4.7.1.

In Use flags

The In Use flags, that are present on all signals, indicate if the signal is available in
the protection relay.
The In Use flag can be handled in two ways:
• The gateway automatically detects what signals are present in the protection relay
and sets or resets the flag accordingly.
• The flag can be set manually by setting, or resetting, the check box in the signal
dialogs.
It is recommended to let the gateway determine the signals that are available in the
protection relay.
If a signal is read from the protection relay, the gateway will report the actual value
of the signal on Profibus. If a signal is not read from the protection relay, the gateway
will report a value of 0xFF (255), 0xFFFF (65 535), or 0xFFFFFFFF (4 294 967
295) depending on the data type of the signal on Profibus.
This mechanism makes it possible to use the available standard configuration
templates in a flexible way, by selecting a template that contains the necessary
signals. If there are signals defined in the template that are not present in the
protection relay, the maximum value for the data type of the signal is reported by
default. In other cases the signal's actual value is reported.
If you do not want the OxFFFF values to cause unnecessary traffic
on the profibus side, you should remove all the parameters that could
not be found in the relay from the configuration and download it
again.This changes the data size on the profibus side. The master
application must be updated accordingly.
