Timing diagrams
Setting / resetting the step without time delay and monitoring time
When NEXT = 1, the
following step can be
activated.
The step enabling condition
must be present at the
COND-
input once only, so that the
NEXT output is set.
If the step enabling condition is met during the
next step, then the
NEXT output from the
previous step is reset.
The step is activated by a “1”-Signal at the RDY input. The block
waits for the step enabling condition at the COND input.
If the conditions are present, the NEXT output is set immediately,
and at the same time the RDY input is reset.
