RS232 with U90 ladder

Recommended Posts

In U90, there are no function blocks to program the communications for your unit.  You will have to use the special functions to program the RS232 parameters and send information over RS232.


You can find example programs in the U90 Help tab for setting up communications.  Also, the help files will outline and explain these special functions.


Hope this helps.
