I am trying to configure OPC-DA with OFS on my ignition Gateway.  
I can read and write tags on OFS client to the PLC.  
I can even browse the OPC tags on my gateway quick client.  
But I can not get the OPC tag data… Tag quality is shown as unknown.  
When I try to **[s | r | w]** , from quick client… there is an error saying config error.

Any help will be much appreciated…

Look in the gateway logs for any error messages, especially ones thrown after you try to read/subscribe:
