Hi AJ,
thanks for the quick answer.

I did everything you said but now I have another problem.
I am looking for a function , to send a predefined packet to the Ethernet Device.
The only function I found is "TLR_QUE_SEND_PACKET_FIFO()", but when I try to compile the programm, following error message appears" error C3861: "TLR_QUE_SEND_PACKET_FIFO": Bezeichner wurde nicht gefunden.", is there a special header file which I have to include first?Or is there another function to sned a packet?

HI,
I found it int the "EtherNetIP Scanner Protocol API.pdf",page 161(Using the macro TLR_QUE_SEND_PACKET_FIFO() will send the packet to the EipEncap-Task process queue).
Because of your reaction I think ,that that was the wrong idea to send a packet.
Could you tell me which basic steps I have to programm to communicate with an ethernet device over the CIFX card?

Hi,
first of all thanks that you have patience with me, but I think step by tep I get into it.

So did I undestand you right that it is impossible to programm the netx of a cifx card??
And I still have the problem that I dont know how to tell the CIFX card , at which IP it should send the packets?

Example:
Get a ping from the device:

|CIFX 50RE(EIP Scanner)|------------>|EthernetDevice(Slave)|
(192.168.1.126)______________________(192.168.1.123)

Hi AJ,

today I tried to write a programm using the CIFX device driver.

HANDLE hDriver = NULL;
	HANDLE hSys = NULL;
	long lRet =CIFX_NO_ERROR;


	lRet = xDriverOpen(&hDriver);

  if(CIFX_NO_ERROR != lRet)

  {

    printf("Error opening driver. lRet=0x%08X\r\n", lRet);

  } 

  else{

	  HANDLE hChannel = NULL;

	  lRet = xChannelOpen(hDriver, "cifX0", 0, &hChannel);

	   if(CIFX_NO_ERROR != lRet)

  	   {

   		   printf("Error opening Channel!");

	   } 

	   else{

		  // xChannelReset(hChannel,CIFX_SYSTEMSTART,1000000);

		   CIFX_PACKET  sendPacket={

		  

			  0,//ulDest   /*!< destination of packet, process queue */ 

			  0,//ulSrc    /*!< source of packet, process queue */

			  0,//ulDestId /*!< destination reference of packet */

			  0,//ulSrcId  /*!< source reference of packet */

			  0,//ulLen    /*!< length of packet data without header */  

			  0,//ulId     /*!< identification handle of sender */

			  0,//ulState  /*!< status code of operation */

			  0,//ulCmd    /*!< packet command defined in TLR_Commands.h */

			  0,//ulExt    /*!< extension */

			  0,//ulRout    /*!< router */

		   };

		    CIFX_PACKET  recPacket={

		  

			  0,//printf("%u\n",tSendPkt.tHeader.ulDest   );//=0;    /*!< destination of packet, process queue */ 

			  0,//printf("%u\n",tSendPkt.tHeader.ulSrc    );//=0;    /*!< source of packet, process queue */

			  0,//printf("%u\n",tSendPkt.tHeader.ulDestId );//=0;    /*!< destination reference of packet */

			  0,//printf("%u\n",tSendPkt.tHeader.ulSrcId  );//=0;    /*!< source reference of packet */

			  0,//printf("%u\n",tSendPkt.tHeader.ulRout   );//=0;    /*!< router */

		   };

			if(CIFX_NO_ERROR != (lRet = xChannelPutPacket(hChannel, &sendPacket, PACKET_WAIT_TIMEOUT)))

			{

				 printf("Error sending packet to device!\r\n");

			} else

			{

				printf("Send Packet:\r\n");

				DumpPacket(&sendPacket);

				if(CIFX_NO_ERROR != (lRet = xChannelGetPacket(hChannel, sizeof(recPacket), &recPacket, PACKET_WAIT_TIMEOUT)) )

				{

					printf("Error getting packet from device!\r\n");

				} else

				{

					printf("Received Packet:\r\n");

					DumpPacket(&recPacket);

				}

				lRet=xChannelIOWrite(hChannel,0,0,0,0,0);

				if((lRet==CIFX_NO_ERROR))

					printf("gut");

				else{

					char szError[1024] ={0};

					xDriverGetErrorDescription(lRet,szError,sizeof(szError));

					printf("%s\n",szError);

				}

		

	   }

	  printf("hat geklappt");

  }

  }

  getchar();

  return 0;
