What version are you using? Have you tried nightly build?

Hello, thank you so much for your reply.

I do not see a place that could tell me the built info. I downloaded the source code from github and built it from there. I am more interested in how to debug this thing. Right now I do not know where should I start.

simple question, what is “CompiledRazorTemplates.Dynamic.RazorEngine_c1571f05d7d34ec897535e2f89d3a77a.dll” ?

In general, it seems a good application, but few thing I noticed:

  1. the OPC ua adapter seems not working. (or I can’t get it to work). I got this adapter from GIthub.

  2. the log utility does not pull the log info automatically. not automatically pulling info seems weird to me. I have to reload the log file every time.

The CompiledRazorTemplates.Dynamic.RazorEngine_*.dll files are simply compiled instances of the web pages openHistorian uses.These are unrelated to OPC.

  1. This is a third party adapter that is not automatically included with the openHistorian, your best bet for assistance on this adapter is to post an issue on the author’s GitHub page
  2. Can you provide more details about which log tool you are using that is giving you trouble?

Thanks,
Ritchie
