OPC Data Logging
Store process data in your database
Modern process integration often calls for factory data to be stored in a database, such as Access, SQL Server, Oracle or MySQL. The OPC DataHub provides a unique configuration interface that makes this task both quick and completely open to customization.

Why use the DataHub for OPC Data Logging?
The top 4 reasons why the OPC DataHub is the best data logging solution available:

OPC DataHub Other data logging products
The OPC DataHub offers two different way to configure the data logging. A quick and easy user interface gets you going in no time, while the DataHub's powerful scripting language allows you to customize the data logging to match your specific requirements perfectly. Other products tend to have a much more complicated user interface making configuration a difficult and time-consuming activity. None of them offers a scripting interface like the one found in the OPC DataHub.
The OPC DataHub is flexible enough to allow you to log data to your existing database tables. You can also easily create new database tables using either the graphical user interface or the scripting interface. Most of the other products impose strict requirements on the format of the database tables they can write to. They do not allow you to write to a database table that is being used by other applications, such as MES or production systems.
The OPC DataHub makes it easy for you to read data from a database and use it as input to you control systems. Read production schedules, recipes and process setpoints from company databases straight into your OPC servers and client applications. Most data logging products only allow you to write to the database, and do not let you read data backfrom them.
The new version of the OPC DataHub has the capability to store and forward data if the connection to the database is broken or the database is busy and cannot respond quickly enough. Most of the other products on the market do not provide anything like the level of protection offered by the OPC DataHub, so if the database is busy or the connection is broken then you will loose valuable data.
