Profibus (optional)
Profibus profiles
The UMG604 can manage 16 profibus profiles.
Each profibus profile contains 128 data bytes

The first data byte of the output area of the
PCS (programmable control system) always

profile required by the UMG604.
To request a profibus profile, write the profile
number in the first byte of the output area of
the PLC.
All system variables and global variables1) can
