Operator
Inputs
Description
none
The output value is the value of the named
NOT
1
The output value is “on” if and only if the intput value is “off”.
OR
2 to 16
The output value is “on” if and only if any of the input values are
“on”.
AND
2 to 16
The output value is “on” if and only if all of the input values are
“on”.
NOR
2 to 16
The output value is “on” if and only if all of the input values are
“off”.
NAND
2 to 16
The output value is “on” if and only if any of the inputs values are
“off”.
XOR
2
The output value is “on” if and only if one input value is “on” and
the other input value is “off”.
TIMER
1
The output value is “on” if the input value has been “on” for the set
pickup time. Once the output value is “on”, it remains “on” until the
input value has been “off” for the set dropout time.
LATCH
2
The output value is the state of a reset-dominant volatile bi-stable
latch, where the first input value is the set input, and the second
input value is the reset input.
Positive one-shot
1
The output value is “on” for one processing cycle following an off-
to-on transition of the input value.
Negative one-shot
1
The output value is “on” for one processing cycle following an on-
to-off transition of the input value.
Dual one-shot
1
The output value is “on” for one processing cycle following either
an on-to-off or off-to-on transition of the input value.
ASSIGN
1
The input value is assigned to the named operand. There is
otherwise no output value.
END
none
The first END encountered terminates the current processing
cycle.
