NI OPC Servers provides a single consistent interface to communicate with multiple devices, saving you from learning new communication protocols and spending time understanding new applications. The combination of NI OPC Servers and other NI products, such as LabVIEW, the LabVIEW Datalogging and Supervisory Control (DSC) Module, Lookout, Measurement Studio, and LabWindows™/CVI™, provides a single platform for delivering high-performance measurements and control to new and existing industrial systems.

You can use NI OPC Servers with the following software applications:

By default, NI OPC Servers installs with the DSC Module for a two-hour evaluation period and with Lookout fully-licensed. NI OPC Servers connects through the OPC client in the DSC Module to enable you to develop a full-fledged Human Machine Interface (HMI) and Supervisory Control and Data Acquisition (SCADA) system with programmable logic controllers (PLCs), programmable automation controllers (PACs), and smart sensors.

NI OPC Servers has both software and hardware minimum system requirements. This application supports the following operating systems:

Note  NI OPC Servers does not support Windows NT/Me/2000/98/95 or the Windows Server non-R2 editions.

NI OPC Servers requires the following minimum hardware requirements:

By default, NI OPC Servers installs with the DSC Module for a two-hour evaluation period and with Lookout fully-licensed. Complete the following steps to install NI OPC Servers if you purchased NI OPC Servers separately from the DSC Module or Lookout.

Note  Some virus detection programs interfere with the installer. Disable any automatic virus detection programs before you install. After installation, check your computer for viruses and enable any virus detection programs you disabled.

NI OPC Servers installed with Lookout is licensed. NI OPC Servers installed with the DSC Module provides a temporary license for a two-hour evaluation period. You must activate a valid license to continue using NI OPC Servers after the evaluation period expires.

Use the NI License Manager, available by selecting Start»All Programs»National Instruments»NI License Manager, to activate NI products. Refer to the National Instruments License Manager Help, available by selecting Help»Contents in the NI License Manager, for information about activating NI products.

NI OPC Servers supports numerous drivers for communication to third-party devices. You can connect to one driver at a time or an unlimited number of drivers simultaneously. To learn about driver usage in NI OPC Servers and to determine the number of drivers you can simultaneously connect to, visit ni.com/info and enter the info code opcdriverusage.

This section lists the new features in NI OPC Servers 2012 and changes from NI OPC Servers 2010.

The most important change made in NI OPC Servers 2012 is the separation of the Configuration and the Runtime. The server Runtime is now administered through a separate administration utility. This separation allows projects to be both created and edited either online or offline.

NI OPC Servers 2012 supports side by side installation for users that already have NI OPC Servers 2010 or earlier installed on the machine. This installation allows users to run both server versions at the same time. It is recommended for users that need to run concurrent tests comparing the old server to the new server. In order to connect to NI OPC Servers 2012, the OPC client must reference a new Program ID.

Note  For Wonderware connections, users must change the application name provided for server connections.

Several changes have been made to the server administration as a consequence of separating the server Runtime from the Configuration. Many settings that impact how a project runs have been moved to the Project Properties, and travel with a project when it is moved to a new PC.

Settings that affect how the server works (such as DCOM configuration) have been moved to the NI OPC Servers Administration menu. Affected functions and processes are as follows:

As previously mentioned, NI OPC Servers 2012 separates the server Runtime and Configuration. This means that users can create or edit a project while online or offline. Since the Runtime uses a default project, users must save the edited online project to an OPC or XML-formatted file in order to move it to another PC.

Project settings can now be accessed through the Configuration by clicking File | Project Properties. Settings include the NI OPC Servers 2010 or earlier Project Identification information, OPC DA, OPC DA Compliance, DDE, iFIX PDB, WW FastDDE/Suitelink, OPC AE, and OPC UA.

In order to address the demand for improved OPC and DCOM configuration security, NI OPC Servers 2012 enforces strict DCOM compliance at startup. This server setting is enabled through the Runtime Options dialog, which is located through the Administration menu by clicking Settings | Runtime Options. The option is located beneath OPC Connection Security, in the checkbox "Use DCOM configuration utility settings." The default setting is checked. In NI OPC Servers 2010 or earlier, this option is located through the Configuration by clicking Tools | Options... | OPC Settings. The default setting is unchecked. This means that as long as DCOM is configured, local clients can connect.

Note  Users that are unable to connect to NI OPC Servers 2012 but are able to connect to NI OPC Servers 2010 or earlier should uncheck this option.

The Advanced Simulator Driver uses ODBC to connect to data sources. When running as a service, users can only connect to a data source defined as a System DSN. When running interactively on the desktop, users should utilize User or System DSNs. It is recommended that System DSNs be used.

Since DDE cannot run as a service, the DDE Client Driver can only be used when the server is running interactively on the desktop.

The InTouch Client Driver works similarly to the DDE Client Driver. It can only be used when the server is running interactively on the desktop.

The ODBC Client Driver uses ODBC to connect to data sources. When running as a service, users can only connect to a data source defined as a System DSN. When running interactively on the desktop, users should utilize User or System DSNs. It is recommended that System DSNs be used.

The OPC DA Client Driver is an OPC DA connection and depends on DCOM just like any other OPC DA client. In order for this driver to work correctly, users must properly configure DCOM on all machines involved in the OPC connection.

This section lists the new drivers in NI OPC Servers 2012 and changes from NI OPC Servers 2010.

NI OPC Servers 2012 supports the following new drivers.

NI OPC Servers 2012 no longer supports the following drivers.
