About data logging<br />

Data log is an <strong>RSView</strong> ® component that collects and stores tag values.<br />

You specify which tag values to collect, when to collect them, and<br />

where to store them by defining a data log model.<br />

Logged data can be stored in an internal file set, or an ODBCcompliant<br />

(Open Database Connectivity) database, and can be:<br />

• displayed in trends.<br />

• archived for future use.<br />

• analyzed using any ODBC-compatible reporting software, such as<br />

Microsoft ® Excel, or Seagate Crystal Reports. <br />
