Parameterization
Before data can be exchanged between the DP master and DP slave,
parameterization is required in addition to the configuration.
The respective configuration tool of the DP master, e.g. SIMATIC HW Config, is
used to set the extended user parameters (Extended User_Prm_Data) for the
station proxy and the I/O modules based on the General Station Description
(GSD file). The individual parameters are set via selectable textual descriptions.
8.5.1
Standard Parameterization
The standard parameterization includes information used to compare planned
and installed I/O modules of a PROFIBUS station. Slot properties, diagnosis,
substitute values and individual operational settings of the respective I/O module
are optional. The scope of the standard parameterization has at least 3 bytes for
digital I/O modules and complex I/O modules need at least 4 bytes of
parameterization data. The following descriptions of the station and module
parameters include the respective length of the standard parameter set.
8.5.2
Structured Parameterization
The structured parameterization allows the master to identify and process the
parameters assigned to an I/O module throughout the station parameters. It
contains structural information such as structure length, structure type and slot
that precede the standard parameters of the fieldbus coupler as the station proxy
and precede each planned I/O module. The scope of the parameterization data
increases by 4 bytes each.
This type of parameterization is only required in conjunction with F I/O modules. It
is then only used if the F-Host application of a DP/V1 master is available to the
slave parameter set to evaluate the F parameters of a PROFIsafe device.
The descriptions of the station and module parameters include the respective
length of the structured parameter set.
More information about the parameters
An exact description of the parameters for the fieldbus coupler and I/O modules
can be found in the “Parameters of the Fieldbus Coupler and I/O Modules”
chapter in the appendix.
GSD files
If structured parameterization of the 750-333 is required, use the GSD files
754_X3n.GSD.
