logging
Data log is an RSView32
™
component that collects and stores tag
values (data). You specify the type of data to collect, when to collect it,
and where to store it by defining a data log model.
The data that is collected is stored in dBASE
®
IV (.dbf) format or
ODBC (Open Database Connectivity) format.
You can display the data in trends, archive it for future use, or analyze
it using third–party software, such as Microsoft
®
Excel, Crystal
Reports
®
, and Microsoft Visual FoxPro
®
.
What is a model?
A data log model defines which tags to log data for, when to log the
data, and what file to log the data to. In the model you also specify the
format of the log files (dBASE IV or ODBC) and when to create and
delete the files.
