Positioning IP 240
The new position number can be transferred to the IP 240 together with SOSY=1. Refer to
Section 10.14.1 for information on how to select a position number.
If there is to be no software-controlled synchronization, you must set SOSY to ”0” prior to the
next transfer of the control bits.

Explanation: A zero offset (NVER) of 1000 is initialized prior to the first transfer of SOSY=1.
A position number with an associated position value of 4000 is transferred
together with SOSY=1.
The actual value prior to the first software-controlled synchronization was 3000,
the new actual value is 1000.
No new position number is selected on the second transfer of SOSY=1, so that
the ”old” position number (position value=4000) is reactivated.
Warning
As software-controlled synchronization is also permitted when the IP outputs are
set and the selected position goes into force immediately, it is possible that the
states of the outputs could change instantaneously, causing a short-term overlap.
Following transfer of SOSY=1, the actual value is reset within max. 5 ms.
