Notes:
Enable Time Synchronization: Once enabled, allow the Server IEC 60870-5-104 ajust the CPU’s
clock when a sync command is received.
ATTENTION
When the time sync option is checked in more than one server, the received times from different
servers will be overwriten in the system clock in a short time period, being able to cause undesirable
behaviours due to delays on messages propagation time and system load.
Transmission Mode of Analog Inputs Events: The frozen counters (Integrated Totals) transmission
modes availables are the following:

It is sent only the most recent analog event

Transmission Mode: The available transmission modes of the frozen counters (Integrated Totals)
are the following:
Freeze by counter-
interrogation command,
transmit spontaneously
Equivalent to the counters acquisition D Mode
(Integrated Totals) defined by Standard IEC 60870-
5-101.
In this mode, the control station's counters
interrogation commands, freeze the counters. Case
the frozen values have been modified, they are
reported through events.
Freeze and transmit by
counter-interrogation
command
Equivalent to the counters acquisition D Mode
(Integrated Totals) defined by Standard IEC 60870-
5-101.
In this mode, the control station's counters
interrogation commands, freeze the counters. The
subsequents counters interrogation commands
(read) are sent by the control station to receive the
frozen values.
