A basic historical transaction group is any transaction group that logs data to a database.

To create a Historical Group

1. In the Project Browser, right-click on the Transaction Groups, and select New Historical Group.
2. Select tags from the OPC Browser and drag them into the Basic OPC/Group Items area of the transaction group.
   The target databases are represented in the Target Name column and when the group executes, the data will be stored in the columns of these names.
3. Go to the Action tab and select Timer to specify how often the group executes.

There are other options that help configure the data as it enters the database. For example, having an additional column for the time stamp.
