Combining logging
You can combine periodic or on-change logging with on-demand
logging. This allows data to be captured at particular times, as well as
when a particular event occurs.
To combine logging
1. In the Data Log Models editor, click the Periodic or On Change
log trigger.
2. Type the DataLogSnapshot command with the or *
(asterisk) parameter, anywhere you can use a macro or command.
Providing a way to log on demand
To enable operators to take a snapshot of data at run time, provide
them with a way to issue the DataLogSnapshot command by:
• creating a button object and using the command as the press
action—operators can then press the button to take a data log
snapshot.
• creating a display key or client key and using the command as the
press action—operators can then press a key to take a data log
snapshot.
Setting up security to log data to a remote computer
If you are logging to a network drive, network share, or ODBC
database that is not located on the same computer as the HMI server,
you must change the Windows ® security settings of the data log
program files and the datalog read server.
