    I'm configuring OPC-server and "talk" to this from Intouch via OPCLink (Wonderware). The log-file at the OPC-server looks to be fine, I can browse all items from OPCLink, but get no values. Any out there have any ideas? Bryn. OPC-logfile looks like this:

    Filter=0xffffffff

    (26.10.2005, 09:44:43.484) Server 2.3.9.1 started

    The logfile looks good, but there are no active items requested by the client.

    Do you have added the items into a group in OPCLink? Then you should see number of active items > 0 in the opc-server logfile and you should see the item values.

    Regards,

    Armin

    As you can see there are some problems with the item-syntax written in Intouch. Corresponding to thes error messages I use the following item-syntax:

    VERDI0 use rVERDI0

    VERDI1 use iPLC_PRG.VERDI1

    STATUS use STATUS

    I've used Intouch a lot of times with OPSLink against other OPC-servers and prefix the items with i - r - d - m according to the OPCLink-rules of addressing items.
