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:

• 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.
