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 Value for parameters P443 and P428
Interface allocation:
SCom1
SCB2
20xx
45xx
Position of the setpoints (16 bit
quantify) in the PZD area:
In the 2nd word
→ 02
In the 3rd word → 03
etc.
xx = 02, 03, 04 (only if control word 2 is
not transferred), 05, up to 16
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).
