Output area of the pro-
grammable controller
1. Byte = profile number
The variables for the
UMG104 follow from the
2
nd
byte.
Profibus (optional)
Profibus profiles
The UMG104 can manage 16 profibus pro-
files. Each profibus profile contains 128 data
bytes maximum.
The first data byte of the output area of the
PLC (programmable logic controller) always
contains the profile number of the profibus
profile required by the UMG104.
To request a profibus profile, write the profile
number in the first byte of the output area of
the PLC.
All system variables can be individually scaled
and converted into one of the following for-
mats:
- 8, 16, 32 bit integer with and without sign.
- 32 or 64 bit float format.
- Big or little Endian
