All PROFIBUS DP and PROFINET IO Fieldbus Couplers
The following assignment applies to the parameters of the I/O module when using
PROFIBUS-DP and PROFINET-IO fieldbus couplers.
Component damage due to incorrect voltage level!
Incorrectly selected voltage levels can destroy the device!
Note when switching between operating modes that RS-232 and RS-485 use
different voltage levels.
Switch off connected devices before changing operating modes!
Make sure that devices you connect support the voltage level of the current
operating mode!
