NOTES
A 'one shot' refers to a single input gate
that generates a pulse in response to an
edge on the input. The output from a 'one
shot' is True (positive) for only one pass
through the FlexLogic™ equation. There is
a maximum of 32 'one shots'.
Operates on the previous parameter.
Operates on the 2 previous parameters.
Operates on the 16 previous parameters.
Operates on the 2 previous parameters.
Operates on the 16 previous parameters.
Operates on the 2 previous parameters.
Operates on the 16 previous parameters.
Operates on the 2 previous parameters.
Operates on the 16 previous parameters.
Operates on the 2 previous parameters.
The parameter preceding LATCH(S,R) is
the Reset input. The parameter preceding
the Reset input is the Set input.
The timer is started by the preceding
parameter. The output of the timer is
TIMER #.
The virtual output is set by the preceding
parameter
