11. 8 Profibus configuration
11.8.1 Profiles
The device can manage 16 Profibus profiles,
each with a maximum of 128 data bytes.
The first data byte in the output box
of the PLC always contains the profile
number of the
Profibus profile requested by the UMG.
In order to request a Profibus profile, write
the profile number in the first byte in the
PLC output box.
All system variables and global variables
1)
can be scaled individually and converted into
one of the following formats:
• 8, 16, 32 bit integer with and without sign.
• 32 or 64 bit float format.
• Big or little endian
2)
.
1) Global variables are variables that the user
defines in Jasic and are available to each interface in the UMG604
2 ) Big endian = high byte before low byte.
Little endian = low byte before high byte.
11.8.2 Device master file
The device master file, abbreviated as the GSD
file, describes the Profibus characteristics
of the UMG. The GSD file is required by the
configuration program of the PLC.
The device master file for your device
is called “0B41.GSD” and is
available on the Janitza homepage.
