5 Setting Groups
VAMPSET
IEC-103 slave number


setting range 1…254 (255 is reserved for broadcasts)
this is used as link layer address and as common address of
ASDU in application layer
IEC-103 bit rate
9600 or 19200 bps
Meas sending interval
This setting is used for restricting the sending measurements. The
next measurement is not sent until the time interval has elapsed
since last sending. During this time the device responses to class
2 poll by „data not available‟ message.
ASDU 6 response time mode
This setting defines which time stamp is sent in response to a time
synchronising message. The following modes are available:
 SYNC
Device sends back the same time stamp that the master sent
in the synchronising message.
 SYNC + PROC
Device adds its internal processing time to the time stamp in
the synchronising message and sends the sum in the response
message.
 MSG
Device sends back its internal time stamp of the first received
bit of the synchronising message from master. This mode can
be very useful because subtracting the time stamp found in the
response message from the time stamp that the master sent in
the sync message gives the time difference between the
master and the device just before the new sync became valid.
 MSG + PROC
Otherwise the same as MSG but internal processing time is
added to the time stamp
Data configuration
Data configuration is divided into Digital and Analog sections. Any
line can be changed or removed and new lines can be added to
both sections.
