From memory, I'd suggest using an OPC mirror application. This would create a client connection to each OPC server (as you can't connect them directly), and allow you to pass data from one server to the other. It's been a while since I looked it this kind of thing, but I think that would work. Kepware and Matrikon both do this type of application I think.

Or if you are storing your DeltaV data from the OPC server into a data Historian, then setup some output tags within the historian, and then pass these through an OPC client which can connect to the Siemens OPC server. It should look something like this in;
Siemens OPC server -> OPC client -> data historian....setup output tag of data to transfer...output tag -> OPC client -> DeltaV OPC server.

I'm sure someone will clarify what I am suggesting is possible.

Colin Welsh answer is correct.
You can implement in that way, but I feel, better to use OPC tunneller(Kepserver and matrikon have some applications) for a headache free communication instead of using DCOM ports while configuring OPC ports. Regular connections between OPC clients and OPC Servers residing on different networked computers rely on Microsoft DCOM communications. This requires the precise configuration of multiple DCOM and Windows security settings for each OPC client and OPC server. In addition, DCOM requires many system ports to be opened so - using DCOM-based communications, and firewalls protected networks is not feasible because the primary job of the firewalls is to locking ports down.

OPC DA can pass FIREWALL or not?

OPC MIRROR is OPC DA and pass Firewall?

In reply to ngovankhoi:

Updated design, As an platform with Siemens ICSS with OPC Server IFIX to transfer data to and from DeltaV OPC Server

How to setup with OPC Mirror ?
OPC Mirror is type OP DA?

In reply to Colin Welsh:

Dear

Update information for design, a platform with SIEMENS Plc and IFIX OPC Server will transfer to and from DeltaV Historian Server ( OPC SERVER ) at another platform through Digital Microwave System at each platform

PLease instruct me how to setup and configure.
IS OPC MIRROR OPC DA Type, and
With OPC Mirror Solutions, can it pass Firewalls?

In reply to ngovankhoi:

Metering Systems, Gas Compressor -> Siemens ICSS with Modbus
Siemens ICSS -> IFIX OPC SERVER -> Digital Microwave -> Digital Microwave -> DeltaV Historian Server (OPC Server )

DeltaV Historian Server (OPC SERVER ) read / store some data of Gas Compressor and Metering package and write some alarms to Siemens ICSS

Please advise me how to do!

In reply to ngovankhoi:

OPC DA can pass FIREWALL or not?
A) Yes, it can pass the information.

OPC MIRROR is OPC DA and pass Firewall?
A) Yes, Just you need to open DCOM port for this OPC in firewall.

Dear,

Does OPC Mirror support for transfer Historian Data?

How to setup DCOM port in Firewall for OPC Mirror?

Thank you!

Dear Youssef. El-Bahtimy,

Thank you!

In reply to ngovankhoi:

In case we want to transfer data in Historian Data Type, we need to use Matrikon OPC Tunneller? Does DeltaV have any software similar function with Matrikon OPC Tunneller?

In reply to ngovankhoi:

I would suggest you have a discussion directly with your Emerson sales channel so they can fully understand your challenge and explain Emerson offering. In addition to having a technical solution, you have to understand any implementation costs. You'll need to talk to them for any licensing you require.

Emerson supports the OPC.NET architecture which is natively firewall friendly. See Product Datasheet below.

Looking online, there are other solutions that support .NET and Classic OPC servers. Unfortunately, I don't think that OPC mirror is .Net compliant. If the Siemens OPC Server is of the classic type, you need a compatible connection on the Client application.

Assuming we get all the connectivity sorted out, you'll also have to consider how much data you are moving, and how much band width you have. You'll be able to tune the OPC bandwidth by adjusting the update rate, and in some cases, be able to apply exception reporting based on minimum signal change. I think you should get some help beyond a discussion in a forum...

Does DeltaV have OPC Server which can re-collect the old data of IFix OPC Server after the Digital Micro Wave Communication between them are restored?
