Configuring data logging

Making runtime changes without editing the data log
model
You can change certain data log parameters at runtime without editing
the data log model. These runtime changes take effect immediately,
but are not retentive:
changing the log rate for periodic logging
changing the log file identifier string
Use these commands anywhere an RSView32 command or macro can
be entered. For example, type the command directly on the command
line.
Changing the log rate for periodic logging
You can change the log rate for periodic logging at runtime using the
DataLogChangeRate <file> <value> [unit] command.
<file> is the name of the data log model
<value> is the numeric portion of the time interval for the log rate.
For example, if you want to log data every 20 seconds, the value is
20.
[unit] is the time unit of the log rate: hundredths, tenths, seconds,
minutes, hours, or days. The default is seconds if you omit the [unit]
parameter.
The change to the logging rate applies during the current logging
session only. When you stop and restart logging, RSView32 uses the
logging rate you specified in the data log model.
