Application To Differential Output - Panasonic FP7 User Manual

5.2 Output Terminal Setting
In this example, "Output terminal polarity" is set to use two kinds of push-pull outputs and the
same Y contact is allocated to two output circuits.
(Note 1) When the polarities are mixed, a warning occurs and the ERR LED on the unit flashes to remind users
to check the wiring. To make warnings not to be announced, set "Warning annunciation" to "Not
announce" in the "Multi I/O Unit Setting" screen of FPWIN GR7 (Ver.1.1 or later), or set the bit 9 of
UM00062 to 1.

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 using ""Allocate
contacts of output terminals"" in the "Multi I/O Settings" 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.
