Omron PLC and Siemens touch screen Communication setting method

OMRON PLC can not communicate with TP177B / DP touch screen,
  But TP177A / DP and other communication with the screen (have repeatedly tested)Specific settings Communication Notes:

(1) All communication settings (HMI and PLC) must be consistent (station number, baud rate, parity, etc.,
   Use the default values ​​here namely: “9600,7, Even / even, 2”);

(2) CPU-42H 4 feet should be appropriated for “ON” position, that is PRPHL Setup, non-Auto;

(3) Select the network type “SYSMAC WAY”, while the network settings driven by:
   “COM1,9600; 7, Even, 2” standard;

(4) The key is to work properly PLC communication in “Monitor” mode;

(5) only in programming mode can only be transferred to the PLC is set to go;

(6) OMRON RS422 (CJ1W-CIF11) expansion modules 1-4 feet set “OFF”,
   5-6 feet is set to “ON”;

(7) If no special requirements, the default setting is usually the best setting;Siemens touch screen connection method OMRON PLC communication line (RS-422A / CJ1W-CIF11)
