The activation res. de-activation of the counter happens via an internal gate
(I gate). The I gate corresponds to the software gate (SW gate).
The
SW gate
is opened (activated) via your user application by an edge 0-1
of the bit SW_GATE_SET of the
control word
in the
output area
. The
software gate is closed (de-activated) by an edge 0-1 of the bit
SW_GATE_RESET. If the I gate was automatically closed at "counting
once", so this may only be opened with an edge 0-1 on SW_GATE_SET.
The following states influence the I gate:
