Emerson TGS Communication with DeltaV via OPC? TangTGD,

Hi, hope you are all doing well.

Please guide me about OPC configuration in Tank Gauging System software and in DeltaV? Also connection/wiring.

If communication via OPC is not possible then please guide about Modbus communication? 

Let us build success,

  Zohaib Jahan ,
  Can you expand on the architecture you're putting together? Are you trying to integrate TankMaster to DeltaV Live somehow?
  
  Rgs,

  Yes I want to integrate TankMaster into DeltaV Live but we have installed TankMaster on different workstation.

  According to this architecture, TankMaster is an OPC Server, in this case, you cannot connect directly to DeltaV Live, you'll need an OPC Mirror for that.

  Since Tank Master is a separate OPC server, it would be integrated to DeltaV via OPC Mirror as Tadeu stated, or you can investigate if the server can be upgraded to OPC UA. With OPC UA, you can use the OPC UA client to pull/push data between Tank Master and DeltaV. You would create DeltaV Control Modules assigned to an Application Station where the Tank master data would reside within DeltaV. From here, the data can be displayed on DeltaV Live as needed.
  
  You could also consider obtaining an OPC UA wrapper product for the Tank Master OPC DA server. There are several companies that specialize in these solutions. Integration Objects is one that I've seen used with DeltaV in the past. The advantage of OPC UA is its ease of use though Firewalls, Security certificates and encryption that can greatly enhance the security profile of the data exchange between the systems. But also, it does not rely on DCOMM and would future proof the installation, versus adding OPC Mirror to your architecture. Microsoft is moving away from DCOMM.
  
  The OPC UA client in DeltaV uses OPC UA Client tags, which will also save some cost versus OPC DA licensing. However, each Application station comes with a 250 tag OPC server, so if these were available, you might not have OPC Tag licensing to purchase, but would require OPC Mirror.
  
  Ideally, your Tank Master has an OPC UA server option and you can configure the DeltaV OPC UA client to directly access the data you need. The OPC UA client is configured entirely in DeltaV as opposed to having to configure a separate OPC Mirror client for OPC DA.
  
  OPC UA in DeltaV does require a system license to enable the OPC UA features. Once in place, you can then use the OPC UA clients available on App Stations and the EIOC. The App STations require OPC UA Client Tag licensing per signal that you configure (OPC Tag value). If you used the EIOC, the configuration is the same but the EIOC Logic Device Tags are licensed via a DST, which allows up to 100 Signals per DST. (just like MODBUS TCP or Ethernet IP protocols).
  
  I recommend going with the OPC UA architecture if you can.
