information on connecting digital outputs.
2.
Click the Control menu.
3.
Click Digital Output.

Once you select the function module, the LED on the
module turns green.
5.
Select digital output port B by clicking Port B.
6.
Click the appropriate bits to select the type of signal to write from
the digital output lines. If the bit is selected, a high-level signal is
output from the digital output line; if the bit is not selected, a
low-level signal is output from the digital output line. Optionally,
you can enter an output value in the Hex text box.

The value of each digital output line of digital port B is output and
displayed on the screen in both text and graphical form.
