5.2.3 Application to Differential Output

It is possible to allocate one memory output for operation to two output circuits and obtain the
differential output by applying the contact allocation functions of output terminal polarities and
output terminals.
• Allocate the same I/O number to the terminals for two sets of four circuits by the setting
"Allocate contacts of output terminals" in the Multi I/O Setting dialog box.
• Allocate "Sink" or "P-type push-pull (positive logic)", "Source" or "N-type push-pull (negative
logic)" to "Output terminal polarity".
• Paired two terminals with the same I/O number are used as a pair of differential output.
In the following example, "Sink" and "Source" are allocated to the "B11-B14" and "B15-B18"
terminals respectively and used as differential outputs.
