OPC Datahub 6.43
Features and Benefits
OPC Tunnelling allows you to connect OPC servers and clients over a network or Internet connection without having to deal with DCOM.
OPC Bridging allows you to connect an OPC server to one or more other OPC servers. This allows you to exchange data between systems that would not normally be able to talk to each other.
OPC Data Logging
The OPC DataHub makes it easy for you to log your OPC data to an ODBC database or text file. You can log data to any ODBC compliant database, such as Access, SQL Server and Oracle. You can also configure the DataHub to store data from your OPC servers into a text file for reporting or transfer to other systems.
OPC to Email
The OPC DataHub can be configured to send an email and text messages whenever an alarm, or regular timer event occurs. The email can be completely customized, with embedded values for any of the data points in the DataHub. You can easily create simple plain text messages or design more elaborate emails with full HTML formatting.
OPC Aggregation allows you to collect data from multiple OPC servers and present it to clients as a single common data set.
OPC to Excel
The OPC DataHub provides drag and drop capabilities for getting live process data into your Excel spreadsheets.
OPC to Web
The OPC DataHub makes it easy to display your real-time process data in a web browser using the leading web technologies, such as AJAX, ASP and Java. The DataHub also includes a built-in web server so you can start publishing live data to web immediately, without having to set up a third party web server. Offering support for new technologies such as AJAX means you can display data on web enabled hand-held devices, telephones and standard desktop web browsers, with no special plug-ins or ActiveX objects required.
OPC Scripting in the DataHub provides a powerful way to attach code to data items and have that code executed whenever the value changes.
OPC to MES & ERP
Using the OPC DataHub you can integrate live production data into management systems and make this data available on corporate management networks.
OPC to Linux & QNX
The OPC DataHub provides an easy way to integrate data from OPC servers with Linux and QNX based applications. Full real-time data access is provided between OPC servers and clients and applications running in Linux, QNX 4 or QNX 6. .
Monitor the performance and critical resources of any computer on your network or over the Internet by running the OPC DataHub. …
OPC = OLE for Process Control
OPC is a software interface standard that allows Windows programs to communicate with industrial hardware devices.
OPC is implemented in server/client pairs. The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware, such as an HMI,The OPC client uses the OPC server to get data from or send commands to the hardware.
The value of OPC is that it is an open standard, which means lower costs for manufacturers and more options for users. Hardware manufacturers need only provide a single OPC server for their devices to communicate with any OPC client. Software vendors simply include OPC client capabilities in their products and they become instantly compatible with thousands of hardware devices. Users can choose any OPC client software they need, resting assured that it will communicate seamlessly with their OPC-enabled hardware, and vice-versa.
The typical OPC connection scenario is a single server-client connection on a single computer as illustrated above, but there are more possibilities. For example, you might need to:
Connect an OPC client to several OPC servers. This is called OPC aggregation.
Connect an OPC client to an OPC server over a network. This can be done with OPC tunnelling.
Connect an OPC server to another OPC server to share data. This is known as OPC bridging.
The OPC DataHub is uniquely designed to do all of these tasks. It is a combination OPC server and OPC client that supports multiple connections. Thus it can connect to several OPC servers simultaneously, for OPC aggregation and OPC bridging. Two OPC DataHubs can mirror data across a TCP network to provide OPC tunnelling.
In addition to enhancing OPC server and client connections, the OPC DataHub can connect any OPC server or client to other applications as well, such as Excel, a web browser, or any ODBC database. And it can also be used to get OPC data into Linux or QNX.
