<p>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:</p>
<p>VERDI0 use rVERDI0</p>
<p>VERDI1 use iPLC_PRG.VERDI1</p>
<p>STATUS use STATUS</p>
<p>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.</p></div>OPC-server2020-02-27T14:38:01.431000Z2020-02-27T14:38:01.431000ZArmin Hornunghttps://forge.codesys.com/u/armin-hornung/https://forge.codesys.com1085a6c7791e18523de169662e499ff32999cd3e<div class="markdown_content"><p>The logfile looks good, but there are no active items requested by the client.</p>
<p>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.</p>
<p>Regards,</p>

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:</p>
