Hello to all, we have a E-designer E-600 screen that has a RS-422 connection hooked to our Mitsubishi Plc FXCU series and an Rs-232 connection that we used to use for connecting our laptop with a serial connection. However,since we had to update our e-designer software we are no longer able to connect through the screen to the Plc like we have in the past. Any suggestions would be greatly appreciated, thanks.
