Setpoint- and Actual Value (P915/P916)

P915 and P916 reflect the configuration of the PROFIBUS telegrams that are used for process da-
ta. The parameters are read only and consist of arrays, where the number of elements corre-
sponds to the number of words in the IO DATA. Each element holds the Parameter Number (PNU)
of the parameter mapped to that particular IO DATA word.
The parameters reflect the latest accepted parameterization data.
7.4.3

Signal List (P923)

The signal list is not saved. It is created at the time of request only for those elements (subindices)
that are requested. The possibility to map vendor specific parameters is examined by asking for
the Descriptor attribute of the specific parameter. It is not possible to map other PROFIdrive
standard parameters than P967 and P968 (Control and Status words).
7.4.4

Drive Reset (P972)

The PROFIBUS master can send a reset request to the application by writing to this parameter. If
the request is rejected an error is returned.

Description
Illegal parameter number (Drive reset not supported).
Request cannot be executed due to operation status.
Request cannot be executed due to operation status.
Drive Profile Parameters (Acyclic Data Exchange)
Value/Description
Holds descriptive text for each fault that is sup-
ported by the option board.
Each subindex corresponds to the event code num-
ber, which means that the accessible subindices are
limited.
The fault description is accessed as an additional
text array.

Parameter numbers of all existing parameters are
saved in the subindices (profile parameters and reg-
ular drive parameters). The array is assigned in
increasing sequence and consecutively. The end of
the list of defined parameters is marked by a subin-
dex with the value 0.
