I have installed PV600 touch screen on a RIO link as a last rack on PLC5-40E. The problem that I have is that updates very slow. I'm sending a few signed integers and looks like the screen updates every couple of seconds and slips trough the values it is getting. The program that is running on the PV600 is not big and I'm using only BTW block since I'm using it as a display only. My BTW instruction triggers every 350ms and sends 20 integers to the PV600. Any idea how to speed it up?
