Profibus profiles
Very many measured values are available in the
UMG96S for further processing. In order to keep
the amount of data to be transferred via the
profibus low, only a selection of the possible
measured values are transferred from the
UMG96S. Selected measured values are sum-
marised in 16 different profiles. It is not possible
to program customer-specific profiles.
The pro-
files are called profile number 1 to 16.
If a specific profile is required from the profibus
master, the required profile number is written in
the 1st byte of the output area of the program-
mable controller. The UMG96S supplies the
current profile number and the conditions of the
three comparators in the first 2 bytes in the in-
put area of the programmable controller. This
is followed by the profile content.
If all the measured values of a profile are not
required, it is also possible to fetch only the ini-
tial measured values from a profile.
The two outputs of the UMG96S can be set via
the 2nd byte from the output area of the pro-
grammable controller. Here the values mean
the following:
Output 1 = Input/Output 1 = Terminal 12
Output 2 = Input/Output 2 = Terminal 13
Profile formats
The measured values in the 14 profiles are in
integer format and can be called up in floating
decimal point format. In addition, the formats
can be delivered with „high before low bytes“ or
„low before high bytes“.
Measured values in integer format (2 or 4
bytes) do not contain any current and voltage
transformer ratios. Measured values in floating
decimal point format (4Byte) already contain
the current and voltage transformer ratios.
