Example 5: Reading a PROFIdrive parameter (array)
In this example, PROFIBUS Parameter No. 945 is used to read
the code of the latest acknowledged fault. As shown in Table 22
on page 103, 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 RPBA-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 and 948 (see Table 22 on page
101). 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 948.
