Note
(for DP interface in slave mode only)
When you disable the Commissioning / Debug mode / Routing check box in the DP interface
properties dialog in STEP 7, all user-specific transmission rate settings will be ignored, and
the transmission rate of the master is automatically set instead. This disables the routing
function at this interface.
Devices capable of PROFIBUS DP communication
