L3 Pushbutton Conversion from 3.8 to 4.0

[Tom Spisak]

I have converted an older 3.8 version program to 4.0 and I need to add an
additional L3pushutton to match the existing one. I copied a existing pushbutton
(cntrl-drag) and redefined it, and also edited the ascii file with no luck.
I push the button and nothing happens (PLC5 via KTX)

In version 4.x you can use Latch Output verify the output was updated. further documentation is in the help files.
