Kane Posted August 28, 2012 Report Share Posted August 28, 2012 I am currently working a program that is similar to a counter. It takes the photo eye pulses sends the TCP packet to a server. The server then interprets the message depending on which line the pulse is from the message will be different. Then updates a database. I am currently testing this program between two V130s. The socket connects it sends the information. It gets a successful bit back from the tcp layer. The problem I have is that the FB Scan just gives me a -1 in the index of message. From what the help says is an invalid format or message to be received. Review PLC master TCP/IP 192.168.10.130 port 5000 makes the connection to PLC slave TCP/IP 192.168.10.131 port 5000 Sends all the messages RX on slave socket accumulate correct number of sent messages FB scan function on slave gives me -1 on index of messages. Also to make the connect tcp work I must give it a true to false transition for it to connect is this correct. It works flawlessly as is but not sure why itd be set up that way?
