OPC browser failing on some tags when using RSLinx. Can’t determine what it is that’s causing some tags to fail, while others don’t. ---

Can you explain the nature of the “failure”? Is there any differences between the tags? What kind of tags are they? ---

Okay, here’s what appears to be the problem. If we have a tag VFD\_110, and we have tags named VFD\_110100, VFD\_110101, etc. the latter tags will not import properly. I don’t know if Ignition is only looking at the first x chars and thinks that the tags are not unique or what. If I rename VFD\_110 to VFD\_110a, then all of the VFD\_110xxx tags import just fine. Hope this helps. ---

Thanks for the additional info. I’ll try to mock this up today and will let you know if I figure anything out. Regards,
