    Default Web Server Pro Light Connection Issue

    I have installed a Web Server Pro Light on an existing Operator V7.6 installation.
    The tablets which connect via the web server work until either they are out of range or they loose packets for some reason (interference etc).

    The issue is that once the tablets loose their connection they will not reconnect even when they are back in range. The only way we can get them to reconnect is to turn them off and then back on again.

    Is there a method which I can use to get the tablets to automatically reconnect without power off and back on? Or maybe a function which would allow re-connection via a pushbutton on the screen.
    Thanks

    Hi Alchall,

    Clients and Web Clients constantly try to reconnect whenever the connection to the runtime server (via the web server) is lost. You can check the log files of the diagnosis server to verify that this is happening and also see, which error is logged when this does not succeed.

    Possibly, the tablet does not automatically reconnect to the wifi whenever it is back in range or there is some other networking issue that prevents the client to connect to the server again.

    Best regards,
    Mark

    The web client has to be installed locally, so that a browser can display projects. (Please refer to the
    browser (on page 4) chapter for the operating systems). The zenon web client is mainly an ActiveX
    control displaying the information in a browser. The display is just as on a normal client. The connection
    to the Runtime server is implemented via the zenon web server using TCP/IP communication.
    The latest installation package for ActiveX Control can be found in the appropriate subdirectory after
    the installation of the zenon web server (Pro) (e.g.:C:/Programme/COPADATA/zenonWebServer/zenon/Version550SP7/zenon_WEB_Client_Setup_GERMAN.E
    XE), and can be prepared on a website for download. You can find further zenon web client setups on
    the zenon web server CD in the Web client versions folder; there are corresponding language
    versions for each version.
    For automatic installation, there are corresponding CAB files for each version and language in the same
    folder as the standard installation setups, for example: C:/Programme/COPADATA/zenonWebServer/zenon/Version550SP7/zenWebCli_GERMAN.CAB.
    All zenon web client setups are digitally signed. So you can make them available for download in the
    internet without any problems. You will find the corresponding certificate information in the zenon web
    client setup properties.

    Regards,
    Lewis
