"Interconnection" of
setpoints
Example 1
8.1-40
The user can select the source from which the setpoints for the
converter are to be taken. This is done in the same way in which
control-word bits are "interconnected". This is now illustrated with two
examples.
The "wiring" of the setpoints is done via parameters P443 (source main
setpoint) and P433 (source supplementary setpoint 1).
Source for setpoints
Interface allocation:
SCom1
SCB2
Position of the setpoints (16 bit
quantify) in the PZD area:
→
In the 2nd word 02
→
In the 3rd word 03
etc.
The main setpoint comes from SCom 1 and is located in the 2nd word
of the PZD area. The supplementary setpoint comes from the USS
interface on SCB 2 and is also located in the 2nd word of the PZD area
(for BICO data set 1).
