Writing to Resource Block

I have an Optek Analyzer, Model C4362. I am communicating over Foundation Fieldbus  and i am able to read expected values using AI blocks. As part of the procedure the instrument needs to be Zeroed prior to every use. This is an enumeration and appears as parameter in the resource block on AMS. I can write to it using AMS. Is there a way to read/write resource block parameters through control studio. 

Thanks,

Subodh

  Have you tried to writing to it using AMS OPC Server? If that works then you can use OPC Mirror to read/write between DeltaV and AMS.

  Hi Lun,
  Thanks for your reply. I have not used AMS OPC server before. If my device tag is called Tag001 and is in Controller01/Card01/Port01 @ address 01, how would I get that over into mirror or another OPC Server like Kepware. I tried creating a new device using the device tag but that does not seem to be a qualified path.
  Thanks!

  Let us start simple scenario first. Use OPCWatchit, change server to AMS.OPCServer.1. I am not sure if this only applies to Server Plus or AMS clients as well. I have only tested this on Server Plus.
  
  Using OPCWatchit Browse look for the "Zeroed" parameter. Again, I don't have your device type so it is hard to know.
  
  For example, I have 644 device and I am able to write to/HSI/DeltaV Network 1/Controller - CTLR-1/I//O - DeltaV/I//O HART Card - C01/Device/CTLR-1C01CH01/Param/sensor1_damping_value/Value.
  
  And yes, I am using HART instead of FF but it should work the same way.
