Question

When I try to communicate to my 250(-1), 260,06 CPU on port 2 RS422 I keep getting the error (#2965 CH3 Time Out error Check the cable and PLC station number).

Answer

If you are using our D2-DSCBL-2 make sure that the wires are connected as shown on page A-4 of the ScreenCreator manual and that blue/white is tied to Green/white, and blue is tied to green.

If making your own RS422 cable make sure that it is connected as follows:

15 Pin     Touch Screen

     7             SG

    10             RD

     9             RD+

     6             SD-

    13             SD+

Jumper 11-14 and 12-15 on the 15 pin port.
