5000 INTERBUS
■
Process Data, PCD.
To enable the use of PCD data, of the VLT®5000
INTERBUS option, the amount of PCD Datawords
has to be configured in Parameter 807, where as the
contents of each single PCD word has to be
configured in Parameter 915 and 916. This can be
done in two different ways: setting parameter 915
and 916, or by using the the INTERBUS object
6000
H
and 6001
H
.
After setting parameter 807 to match the desired
amount of PCD Data, the VLT®5000 needs to be
configured, for assigning Parameters to each single
PCD words. The VLT®5000 stores this information
in Parameter 915 and 916. The INTERBUS objects
6000
H
and 6001
H
are images of the two Parameters.
Changing Parameter 915/916 has immidiatly effect
on the PCD data.
The drawing below shows the relation between the
INTERBUS object 6000
H
/6001
H
and VLT®5000
Parameter 915/916.
The INTERBUS Object 6000
H
and 6001
H
is an Array of
words that has following structure:
The sub Index number 1 contains the number of
process data bytes. For each byte of process data
2 sub indexes are used. Sub index 2 contains the
Object number, sub index 3 is the index of the object,
if the object is of type array. The next two indexes are
for the next byte of process data. If a Object is of type
Word it uses 4 Sub indexes, wheras the three last Sub
indexes are not used, and must be set to zero.
The 6000
H
6001
H
Objects can have from 9 up to 37
Sub indexes depending on how many PCD words
there has been assigned. The drawing below shows a
configuration with 2 PCD words assign for reading
parameter 520 (Current) and parameter 528 (digital
input). For writing parameter 204 (minimum reference)
and parameter 221 (Torque limit) is used.
The output data to the VLT®5000 can be disabled by
Interbus Object 6002
H
.
By setting the Interbus object
6002
H
to 00
H
all imcomming process data wil not be
transimitted to the VLT5000. Setting Interbus object
6002
H
to FF
H
reactivates the updating of output data.
After a power up the option always sets objects 6002
H
to FF
H
.
Writing to Interbus Object 6001
H
automaticly sets object 6002
H
to 00
H
an
thereby disables the inputs. The user has
to write 0FF
H
to Object 6002
H
manually.
