In this case, the timeout value should be increased correspond-
ingly.
Profile:
• Under PROFIBUS, there are usually the profiles DP, Standard
und User defined.
• The profile must be selected that is already used in the
programmable controller.
Bus parameters:
• Unlike the MPI bus profile, the bus parameters for PROFIBUS
are not constant and change with the type and number of
PROFIBUS stations used.
• Always set the PROFIBUS parameters that are set in the cur-
rently used programmable controller (see current STEP7 pro-
ject).
Whenever an active CPU is involved, which transmits the pro-
fibus parameters, we recommend activating the "Automatic
transmission rate detection".
