Hello, I am trying to open a server socket by using the FB TCP_SOCKET. The status says that the socket is listening, but the parameter ACTIVE stays FALSE. Thus, no data can be received. Where is my error?
Hi Götz, I think the ACTIVE output only goes TRUE when a TCP client connects to that server. When you try establishing a connection from a client (like another TCP socket), does that make a difference?
Thanks Martin, you’re right. Just 2 remarks: - your Information should be added to the docu - after project modification a could start is required - if you agree this info should also be documented
OK, glad the problem is solved. I will pass your suggestions to the PLCnext Engineer developers.
