Unitronics/Visilogic, choc moze i inne tez.

P.S. Ha ha - RTFM :-)

"According to IEC 1131 - 3, it is possible to create Ladder Diagram
nets that contain feedback loops, i.e. where an element is used as
both contact(s) and coil(s) in the same net. In Ladder Diagram,
all external input values such as those associated with contacts
are gathered before each net is evaluated.
[...] In the above example:
Where the net uses the state of its own output, the value of FAN
(MB 7) coil associated with an inverted contact of MB 7 is always
the value resulting from the previous evaluation.
However, if the value of FAN (MB 7) is used in any following nets,
the latest evaluated state is used. "

Choc zaczeło sie od tego ze nie moglem sie doczytac tego odnosnie
blokow arytmetycznych/funkcyjnych :-)
