Technical data

Note
If the organization blocks called are not programmed, the user
program is
continued.
If a timeout occurs, the CPU reads in the substitute value "00H"
and continues to work with this value if the QVZ is
acknowledged.
A timeout, however, increases the runtime of the STEP 5
operation that caused it.
STOP in the case of QVZ If you want a timeout to cause the CPU to stop, you must program the
stop operation STP in OB 23 or 24.
You can also program DX 0 to cause a system stop in the event of a
timeout without programming OB 23/24.
