Profibus profiles
There are many measured values available for
transmission. To keep the data to be transmitted
via Profibus small in number, only a selection of
the possible measured data will be transmitted
by UMG96S. The selected measured values are
combined in 16 different profiles. The
programming of specific data is not possible.
The profiles have the description of profile
number 1 to 16.
If a certain profile is required by the Profibus
master, please write the desired profile number
into the first Byte of the output range of the PLC.
The UMG96S supplies the input range of the
PLC with the first 2 Bytes of the actual profile
number and the condition of the three compara-
tors.
If not all values of the selected profile are
needed, you can pick the first measured values
from a profile only.
Via the 2nd Byte of the output range of the PLC,
the two outputs of the UMG96S can be
activated. The relation is:
Output 1 = Input/Output 1 = Terminal 12
Output 2 = Input/Output 2 = Terminal 13
Profile formats
The measured values can be retrieved in 14
profiles in integer and floating point format. Ad-
ditionally, the formats "high before low byte" or
"low before high byte" can be provided. Meas-
ured values in integer format do not contain
current and voltage transformer ratios.
