Input 297
This ensures that the device turns on at the selected axis position
regardless of axis speed.
Output cam with actuation delay is most accurate when the delay is short
and the speed constant. Sharp acceleration near the point where the output
must be actuated may cause inaccuracies in the timing of the output, and
may even cause some flickering of the output as the axis enters and exits
the cam window. Use command position rather than actual position
whenever possible, because it is smoother.
Tag Explorer
If you selected Enable, select the type of output.
Tag Window
If you selected Enable, select a discrete output.
Input
Use an Input block to execute one of these three commands:
Wait for Input On pauses the current task until the selected Dedicated
(axis-specific), Miscellaneous, or Configured (AxisLink, RIO
Adapter, RIO Scanner, SLC, or Flex I/O discrete) input is on.
Wait for Input Off pauses the current task until the selected Dedicated
(axis-specific), Miscellaneous, or Configured (AxisLink, RIO
Adapter, RIO Scanner, SLC, or Flex I/O discrete) input is off.
If Input branches program flow to the top (true) node if input is on, or
to the bottom (false) node if input is off.
The Input block resides on the Main Palette.
There are two pages to the Input block. The first page requires you to
make entries in the Type and Input Class fields. The second page is
dependent upon your selection for the Input Class field.
