ˇ@

  Ans:  

  The WinCon-8xx7/8xx6 can setup up to five Modbus RTU slave ports in COM2 or COM3 or in COM5, COM6, COM7
  COM8 (multi-serial ports of I-8142/8144/8112/8114 in slot 1 or 2) since the driver version of 3.25.

   Note:
   1. Modbus RTU slave port 1 can be COM2 or COM3 which can be set on the "WinCon's monitor" by mouse .
   2. User may enable 2nd , 3rd , 4th or 5th Modbus RTU slave port in COM5 , COM6 , COM7 or COM8 only. (No
       support other COM port number)
   3. Before using this function, please make sure COM5 , COM6 (or COM7 , COM8) does exist and well configured.
   4. Via 2nd, 3rd, 4th or 5th Modbus RTU slave port, user may use ISaGRAF to Debug/Set_val to the controller, however
       user can not Stop/Download/Update the ISaGRAF program.
   5. To Debug/Set_val/Stop/Download/Update the ISaGRAF program, please use Ethernet port (or Modbus RTU slave
       port 1, COM2 or COM3 if enabled). COM5 to COM8 is not for ISaGRAF to Stop/Download/Debug.

   How to setup ?
   Please connect ˇ§Rtu_slavˇ¨ in the ISaGRAF IO connection window as below. Re-compile the project and download to
   he WinCon via Ethernet (or first Modbus RTU port if it is enabled)
