OK, I am temporarily giving up on Serial FINS.....
Have a new project, Omron Serial HostLink is my serial comm method. 9600, 7, E, 2, COM2 (as before with FINS serial).
Have just 1 basic button. PLCAdress click is 6.0, PLCAdress HighlightX is 0.0 (as before with FINS serial).
When I click on the button, expecting to hear a relay click I get 'OMRON ERROR' on the button.
What do I check?
