NOTE
Inverting the Timer 1/2 output signal does not affect how the delay modes work. Note
that due to the inversion of the Timer 1/2 output signal, a set switch-on delay, for
example, can act like a switch-off delay.
Inverter 1/2 inverts the logic state of the Timer 1/2 output signal.
Q
L1
/ Q
L2
output the result of the Smart Task. The state of Q
L1
is output via pin 4 (unless
pin 4 is used as an IO-Link interface).
Pin 2 can output the Q
L2
state or alternatively be configured for other purposes. Pin 4 is
therefore also called MF (Multi Function). The following configuration is possible:
•
External input: If pin 2 / MF is configured as External input, this is available for
selection in Input selector 1/2
•
Blocked beams hold: If the input signal is 1 (“HIGH”), the Blocked beams hold function
is set. In this case, once interrupted, beams remain set or are held. Thus, only
one status change of a beam from 0 to 1 is possible. This function is suitable, for
example, to determine the highest point of an object.
If the input signal is 0 (“LOW”), the Block beams hold function is deactivated. The
Blocked beam hold function is deactivated. The process data is no longer held.
