transmitted more irregularly by the CPUs. In these cases, it is better to avoid
automatic detection of the bus parameters.
5.1.2.2 PROFIBUS configuration
Basically, the same applies to PROFIBUS configuration as to MPI
configuration. However, the network-related parameters are more extensive.
In addition to the parameters transmission rate and highest station address
mentioned in section 5.1.2.1, PROFIBUS also has parameter field for
selecting the bus profile and bus parameters:
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.
The PROFIBUS parameters should always be set equal to the parameters
of the currently used programmable controller (see STEP7 project).
