The OPC-COM Tunnel Module is working great!

The only minor issue I found (and it may have nothing to do with Ignition) is when I copy and paste an existing connected SQL Tag subscribed to a Cimplicity OPC Server through the tunneler, the original tag goes stale. I believe the reason for this is that it opens a new subscription and a drops the previous one.

Other than that, it is flawless!! Great job guys!! ![:thumb_right:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/2026e28c0c425034352c1b75807edf956adc75f4.gif ":thumb\_right:")

Hi,

Sorry it took so long, but we’ve fixed the problem with multiple subscriptions to a single tag. The download link has been updated to beta 2.

Just downloaded the tunneller module and installed it.  
When I went to the module configuration page it reports version 1.0.0 (b0).  
It this the b2 version but just shows as beta 0?

Just want to clarify which version it is.

That “b0” that it’s reporting in the build number. It’s not quite accurate, but I wouldn’t be too concerned about it.

However, from now on maintenance of the module will be published through the [module store](http://marketplace.inductiveautomation.com/moduledetail?2&moduleId=47).
