Hello, i have a problem connecting to any plc on site because when i do i get this message :-
" An unusable com port was specified. Execute again after checking com port setting." <ES:01808009>.
I have had this before, and it was right. The com port setting had indeed been changed to com port2, when it should be com port 1.
So i changed it and away i went happy.
I have ensured it is in com port 1 and have tried changing it to com port 2 and back again, but no joy this time.
Any ideas please.
