    The easiest way should be to leverage the Web Browser element under Special Controls under the Visualization Toolbox. From there, fill in the URL data (http://x.x.x.x:8080/webvisu.htm) and a boolean for Show and that should be it. You should see the other PLC's visualization inside the current PLC's visualization.

    In 3.5 SP16 Patch 1 is it possible to Online edit the logic in a Function Block without needing to go into program mode?

    first of all, don't try to place the inserted element at the end, but test at the actual halved length element. If it is lower and you are going for ascending, then add the halved remaining number of elements to the top, and repeat. Repeat whole till the last lower checked element and the last upper checked element are contiguous.

    @dFx, not sure what you meant by "If elements are swapped, then approximate the new index by halving the distance to the max possible (needs two index memory more)."

    Probably the easiest approach to this is to implement a heartbeat. Server sends client a dummy message (e.g. "HI") every X seconds to keep connection alive (when you are not regularly sending data to client). Client also sends server a dummy message (e.g. "HI") every X seconds to keep connection alive (when you are not regularly sending data to server). If either side does not receive this dummy message within Y intervals of X seconds, then close connection. In each client/server function block,...

    Hi, I updated device. But it was not a problem. The problem was in network connection. I had ethercat device connect to one router with Profinet and ethernet devices. Now i have profinet and ethernet connect via wi-fi and ethercat via network card and almost all work fine. i have problem with ethernet device JXC9 connect via wifi (router WNDR3700v2) . info from loger con not connect to IoDrvEthernetIP. IF i connect via network card everything work ok. Do you have any idea?

    1.SysSockCreate 2.SysSockBind 3.SysSockListen 4. After completing the above 3 steps, use SysSockAccept to receive the client socket. 5. Push the received multiple client sockets into a SOCKET_FD_SET structure How can I know which socket has data coming in? The following is my test code, I found that SysSockselect can only detect SOCKET_FD_SET.fd_array[0]. Suppose I save the second TCPSocket into SOCKET_FD_SET.fd_array[1]. When data comes, SysSockselect cannot detect it.
