Profibus configuration
11. 7. 1 Profiles
The device can manage 16 Profibus profiles,
each with a maximum of 128 data bytes.
The first data byte of the PLC's output range
always contains the profile number of the
Profibus profile requested by the UMG.
To request a Profibus profile, write the profile
number to the first byte of the PLC's output
range.
All system variables and global variables
1)
can
be individually scaled 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. 7. 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 “u6050c2d.GSD” and is available
on the Janitza homepage.
