Am very new to PLC, and waiting for my first T100MD. Just want to know how I can make a simple menu on the LCD-420 with UP/DOWN button as inputs? Make it clear for you:
Option 1: print GOOD MORNING
Option 2: print GOOD AFTERNOON
Option 3: print GOOD EVENING
Option 4: print GOOD NIGHT
User choose any of the options, and PLC will execute the command and send it to LCD-420
