Does DeltaV OPC Server support 64-bit OPC clients?
DeltaV OPC Server does not accept connections from 64-bit OPC clients. The OPC client application must be running as a DeltaVAdmin user.
Does DeltaV run as its own Windows service?
The DeltaV OPC Server does NOT run as it's own Windows Service. As in, if you type services.msc and go hunting through that list, you won't find anything that resembles the OPC server. But if you type taskmgr and look through the programs that are running, you'll see FrsOpcDv.exe. That, right there, is the DeltaV OPC Server.
Why can't I connect DeltaV to a pi-OPC interface?
What's crazier is that DeltaV is hard-coded to block anonymous access, which means your OPC client must be running as DeltaVAdmin (or equivalent). If you're connecting DeltaV to a PI-OPC Interface, make sure the interface is running as "DeltaVAdmin".
Why won't my DeltaV service start?
If you have access, look at CTS NA-0800-0067. I faced a similar issue and this solved it. Basically it can happen that an OPC client is connecting to the DeltaV OPC server while the machine is starting up. If the OPC service starts up before the DeltaV service, the DeltaV service will not start.
What is DeltaV Remote Client?
DeltaV Remote Client is a thin-client application that connects through a DeltaV server (the DeltaV Remote Client server) that is set up with the Microsoft Remote Desktop Server (formerly Terminal Server) role enabled. Supported DeltaV servers that can have this role enabled are: ProfessionalPLUS, or a DeltaV server licensed as a Base Station or Operator Station. DeltaV Remote Client provides full remote capability to all DeltaV applications configured for remote access. These remote workstations are physically connected to the Remote Desktop Server through the L2.5 network.
What factors affect the performance of a DeltaV remote client?
There are many factors that will influence the performance of the remote client including communications method and speed, type of server used for the DeltaV Remote Client server, type of computer used as the remote client, number and type of sessions connected to the DeltaV Remote Client server.
How does DeltaV impact performance?
For the DeltaV Remote Client server, the model and configuration of the hardware will impact the performance. Remote client device hardware can also make a difference in performance. When the remote client is used for operator interface applications, the CPU speed plus the memory and type of video card can make a 1 to 2 second difference in the display call up times between older slower PCs and the new, faster PCs with improved bus and video capabilities. Response times for engineering activities are not impacted by differences in the remote client device hardware. Additionally, if other software applications are running on the remote client device, the performance and software integrity may be affected.
Can you use a DeltaV remote session as a maintenance station?
The remote sessions can also be licensed as a DeltaV Maintenance Station to allow your maintenance shop to use the remote client to monitor device alerts and DeltaV system health from any PC. Since the client can make connections to multiple systems at the same time one computer can serve as the Maintenance Station for several DeltaV systems.
Can you open multiple windows on DeltaV?
From a single remote client you can easily open multiple windows to simultaneously view different DeltaV systems.
Does DeltaV support remote client?
Full support cannot be provided if the device is running any other software.
Cannot Connect to The DeltaV Database Server

How to connect to DeltaV OPC server?
There's only one way to connect to DeltaV OPC Server and that's with a local user account. The one that's pre-configured is called, "DeltaVAdmin." This account has to exist on the DeltaV App Station as well as the PROPLUS for the data to get sent.
What is an OPC remote?
OPC Remote refers to the software you need to install on the OPC Client to be able to talk to DeltaV OPC. I found this strange because when I was the PI OPC Interface to a KEPServerEX, OSI provided all the software for the OPC client and Kepware provided all the software for the OPC server.
Does DeltaV OPC run as a service?

Can you use DeltaV as an OPC?
What's crazier is that DeltaV is hard-coded to block anonymous access, which means your OPC client must be running as DeltaVAdmin (or equivalent). If you're connecting DeltaV to a PI-OPC Interface, make sure the interface is running as "DeltaVAdmin". This is basically your only option to getting it to work: you cannot use the local SYSTEM account.
How to ensure OPC connection is secure?
To ensure that an OPC connection is secure, create users and groups that are exclusively for this use. These can be manually added by any user who has the proper credentials to do so.
What is OPC server?
The OPC server stores OPC specific information in the registry. Since OPC clients need to be able to discover servers running on both the same machine and remote machines, there needs to be a standard method for accessing this registry information (which is not available for remote access). To do so, a component called OPCEnum is provided by the OPC Foundation. OPCEnum is an executable that is typically installed on a computer along with the OPC server. It runs as a System service and provides a means to browse the local machine for OPC servers and then expose the list to the OPC client.
What should be considered before DCOM?
Before DCOM is configured on the server computer, both the level of security and the Runtime's process mode should be considered. To provide the highest level of security, users must enable the appropriate settings. The process mode should be chosen since the DCOM configuration is reset when the process mode is changed.
What is a DCOM?
Distributed Component Object Model (DCOM) is an extension of Component Object Model (COM) that allows COM components to communicate among objects on different computers. DCOM uses Remote Procedure Call (RPC) to generate standard packets that can be shared across a network, which in turn allows COM to communicate beyond the boundaries of the local machine.
Why is DCOM enabled?
This option, which is enabled by default, ensures that DCOM settings are obeyed and user authentication is performed. Disabling the option is not recommended since the server will impersonate the security of the client when performing any actions on behalf of the client application.
What is network discovery?
The Network Discovery setting was first introduced in Windows Vista and allows or prevents the computer to detect or be detected by other computers on the network. If the setting is off (or if it is not set as an exception in the firewall) OPC clients might not be able to browse for the server.
Can multiple OPC servers communicate?
Multiple OPC servers can typically communicate to an OPC client. Most OPC servers have a test OPC client embedded, so that connections and sample data can be tested, but the test clients are not designed for generic OPC client use.
Can OPC servers communicate with OPC servers?
As a rule, OPC servers do not communicate with OPC servers.#N#An OPC server communicate with an OPC client. Multiple OPC servers can typically communicate to an OPC client.#N#Most OPC servers have a test OPC client embedded, so that connections and sample data can be tested, but the test clients are not designed for generic OPC client use.#N#Each of the OPC server vendors seems to have a special product that will allow an OPC server to talk to another OPC server, and I'm sure those advocates will pop up with their respective solutions.
