3.4 Technical data
INFORMATION!
Although the PROFIBUS MBP technology supports power supply via the PROFIBUS line the
"signal converter PROFIBUS MBP interface" will operate only if the additional power supply for
the device is connected / available.
For a detailed description please check the signal converter handbook. Refer also to the
PROFIBUS PA user and installation guideline (Version 2.2, February 2003 PNO order no. 2.092).
