In the Unsolicited messaging function, the Message can be voluntarily notified from CNC to the personal computer according to the instruction of the ladder program or the NC program Note1). So, in the PC application, the state of CNC can be observed without the polling process. Arbitrary data of PMC or Macro variables Note1) can be transmitted as the Message. In the PC application, the polling process to inquire the state of CNC regularly becomes unnecessary by using this function.

The unsolicited messaging issues the window message to the PC application internally and notifies the Message. So, Visual C++ is necessary for making the application.

Note1) NC program and Macro variable can be used only by 30i/31i/32i/35i, 0i-D/F and PMi-A.

This function is supported at the following ethernet function.

The following setting is necessary to CNC beforehand, to use the unsolicited messaging function.

- IP address :
IP address of destination PC.
- Port number :
TCP/UDP port number of destination PC.(Note:The unsolicited messaging function uses TCP and UDP of the same port number.)
- Control parameter
It is PMC address or macro variable number to demand the data transmission by the ladder or the NC program.
Only PMC address ("R","E") can be set for Series 16i/18i/21i, 0i-B/C, and Power Mate i.
- Transmission parameter
It is the PMC address and size or the macro number and numbers which becomes the content of the message.

- Timeout time :
imeout time to observe communication board transmits data.
- The interval time of the existence signal :
The interval time of the existence signals which are transmitted while communication board operates.
- others :
Please refer to the specification of function for details.

These data can be set from the PC application using cnc_wrunsolicprm() or cnc_wrunsolicprm2().

When you set these data in CNC, these data is saved in S-RAM area of CNC.

1. Set the parameter for the unsolicited messaging to CNC.

   The parameter for the unsolicited messaging function is set to CNC SRAM area using cnc_wrunsolicprm(). The parameter can be read by cnc_rdunsolicprm(), if necessary.

2. Notify the completion of preparing the unsolicited messaging to CNC.

   The completion of preparing the unsolicited messaging is notified to CNC using cnc_unsolicstart(). After this call, CNC part can send the Message.

3. Add the function to process the unsolicited messaging.

        // Example of ON_MESSAGE
        #define WM_MYMESSAGE (WM_APP + 1)
        BEGIN_MESSAGE_MAP( CMyWnd, CMyParentWndClass )
            //{{AFX_MSG_MAP( CMyWnd
            ON_MESSAGE( WM_MYMESSAGE, OnMyMessage )
            //}}AFX_MSG_MAP
        END_MESSAGE_MAP( )
   
        LRESULT CMyWnd::OnMyMessage(WPARAM wParam, LPARAM lParam)
        {
            LRESULT result;
            // Process the Message from CNC using cnc_rdunsolicmsg(), etc.
            return result;
        }
   

   The arguments of the OnMyMessage() function are as follows.

   wParam

   = -3 : The socket communication error occurred.

   = -2 : The unsolicited message server has stopped.

   = -1 : The CNC power was turned off.

   = 0 : The Message from CNC arrived. (normal process)

   = 1 : The CNC power was turned on.

   lParam

   = "Handle for the Message data reading" : in case of wParam = 0 This value can be used as the argument for cnc_rdunsolicmsg().

   = 0 : Other than wParam = 0

   Note)

   In case of "wParam = -3" :

   The "Handle for the Message data reading" on the CNC side becomes invalid, so call cnc_unsolicstart() again. When the problem is not solved, investigate CNC power supply, Ethernet cable and I/F board.

   In case of "wParam = -2" :

   The window message cannot be received at the application. So, both the restart of the application and the Unsolicited messaging server is necessary.

   In case of "wparam = -1" :

   The application should wait for the wParam to become "1". And it is necessary to execute the acquisition of the library handle again.

   And the OnMyMessage() function can set "RES_CODE" of the PMC data for unsolicited messaging control by setting the return value in "result" when wParam=0. The value of "result" which can be set by the application is as follows.

   result = 0x00, 0x10..0x1F, 0x30..0x3F

   Read the unsolicited messaging data.

   The transmitted message data at above OnMyMessage() routine is read by using cnc_rdunsolicmsg().

   Notify the termination of receiving the unsolicited messaging to CNC.

   The termination of receiving the unsolicited message from CNC is notified by cnc_unsolicstop() when the PC application finishes.

In Windows Vista, the CNC unsolicited message can not be received when the application for message receiving is executed as "Run as administrator".
