I want to call this function 30 times (with different ID and IP for the TCON function) In the FB, I defined a variable like this: DB_Com as "TCON_IP_v4" and I set the value as follow: L 64 T #DB_ComCh.InterfaceId L #ID // Input parameter of FB T #DB_ComCh.ID L 16#0B T #DB_ComCh.ConnectionType SET = #DB_ComCh.ActiveEstablished L 192 T #DB_ComCh.RemoteAddress.ADDR[1] L 168 T #DB_ComCh.RemoteAddress.ADDR[1] L 1 T #DB_ComCh.RemoteAddress.ADDR[3] L #IP // Input parameter of FB T #DB_ComCh.RemoteAddress.ADDR[4] L 2115 // I need this for the device that I want to connect T #DB_ComCh.RemotePort L 0 T #DB_ComCh.LocalPort I do this before call the TCON function. My problem is that the TCON function goes in error with the status 16#80A4 and I don't know what I have to do. Thank for replies

You can find this information in the online help of TCON as well as in the TIA manual. Regards, Kaulquappe Hi Kaulquappe and thanks for the reply I read the help but I don’t understand. I’m sure that the IP is correct. If I disconnect the cable of the device I cannot ping it. So no other device use that IP. If I try the TCON outside the FB and define the “CONNECT” DB from the properites of TCON, I can estabilsh the connection. So the problem looks something else.

Kaulquappe Posts: 3093 Rating: (324)	Hello, well, in this case it seems to be a logical / timing error in your program. Use a break point when calling TCON and check the IP in the online mode of the TCON instance DB. Regards, Kaulquappe

Thank for replies Little bit embarassing There's a copy and paste error, I assign "#DB_ComCh.RemoteAddress.ADDR[1]" 2 times
