Sharing data with other
Windows applications
Methods for sharing data
RSView32 ™ is based on standards that allow data to be accessed and
shared among Windows ® applications. With RSView32, you can:
retrieve historical data using other Windows applications
RSView32 stores all historical data in dBASE ® IV (.dbf) format, so
you can access data from log files using any software that supports
this file format. With data logs, you also have the option of storing
the data in ODBC-compliant databases. With activity logs and
alarm logs, you can optionally send the data to an ODBC-
compliant database.
This chapter includes a procedure for accessing data from activity,
alarm, and data log files. It also shows one way to display historical
data using a pivot table created in Microsoft
® Excel.
access and update tag values
RSView32 works as a DDE (Dynamic Data Exchange) server and
client, as well as an OPC
® (OLE for Process Control) server and
client. This means you can exchange tag values with a wide range
of devices and other Windows applications.
You can also use the RSView32 Object Model to read and write tag
values, or to execute RSView32 commands from another
application. For more information about using the RSView32
Object Model, see Getting Results with RSView32, and see Help.
