Can't browse tags with OPC DA Datasource
-
Hi All,
I have created OPC DA Datasource at Mango v4.0.0.beta5 on Windows server. Although, OPC Server seen on the Serves List, I got a "Request Timeout" error when I Browse Tags on OPC DA Tools. What could be the possible reason?
Additionally, OPC server and Mango are installed on the same server. And also, we can connect and browse tags by using Matricon application on the same server.
Thanks in advance,

Hi Nurr
if the OPC server and Mango are on the same server you should be using
localhostas the host name -
Hi @CraigWeb ,
I changed host with localhost and browsed tags on the OPC DA Tools tab. Then, I added some points but can not get values.
Additionally, when I change host with localhost, I got an "BAD_QUALITY" error like below.

Hi @Nurr
I looked at the code where that error originates from. Before the data source looks at the value it looks at the quality of the tag. If the quality is bad then the DS will throw an error and ignore the value. You will need to figure out why the server has bad quality for those tags. But at least you are getting a response from the server.

@CraigWeb thanks. we got this error, when the device is offline on the site. As a result, we successfully get the data with OPC DA.
