PROFIBUS-DPV1 functions
155
11/04 MN01219002Z-EN
An output can be assigned with either a switching signal
(output Q0 to output Q5), a motor-starter function (output
Q0 to Q3) or the remote operator function (output Q4 and
output Q5).
Assignment of the outputs with switching signals
The following table indicates the possible assignment of
outputs Q0 to Q5 with switching signals and the
corresponding value for the Octets 1 to 6 of the Object.

When accessing the “Star-delta changeover time” data
content, please note the Motorola coding format (Octet N:
High-Byte, Octet N+1: Low-Byte) used in PROFIBUS-DP. If
the data processing format in your DP master system
deviates from this standard, and the DP access commands
do not automatically include a conversion, it will be
necessary to implement and perform the conversion in
your application program. Please refer to the
documentation of your DP master system.
h
Only outputs whose switching signal has been assigned
with “Bus access” can be switched via the PROFIBUS-DP.
