Hey guys,

I’m using the 4PPC30\_043F\_21B PLC, and I’m wondering if it has the capability to browse for OPCUA tags. Would it be possible for it to find OPCUA tags from an OMRON PLC?

Thanks!  
Jack

This is possible only with AS\AR6. AS\AR6 contains new AsopcUac library with function UA\_Browse().

I decided to expand on this topic with a new forum post, but I’ll see if my PLC can do this library in the meantime.
