Example 5: Reading a PROFIdrive parameter (array)
In this example, PROFIBUS Parameter 947 is used to read the
code of the latest acknowledged fault. As shown on page 125,
parameter 945 is of the array type with subindexes 1, 9, 17 and
25.
The slave returns the code of the latest acknowledged fault
(2300h). The fault codes are according to the DRIVECOM
standard. See also the User’s Manual of the drive for drive-
specific fault codes.
The implementation of the PROFIdrive profile in the FPBA-01
supports the storage of the active and the five latest occurred
different faults in the fault buffer. The fault codes can be accessed
by PROFIdrive parameters 945, 947 and 948 (see page 123). The
value zero indicates no fault. The subindexes of these parameters
are related to each other, i.e. parameter 945 with subindex 1
relates to subindex of parameter 947 and 948.
