6.6.4 DATA LOGGER
The data logger feature allows the PQM to continuously log various specified parameters at the specified rate.
The data logger uses the 64 samples/cycle data. This feature is implemented into PQMPC as shown below.
1. Select the
Setpoint > System Setup
menu item to setup the data logger feature. This launches the System
Setup dialog box shown below. Select the
Data Log
tab to display the data logger parameters.
The state of each data logger and percent filled is shown. Use the
START
and
STOP
buttons to start and
stop the logs.
In the
CONFIGURATION
settings, the
Log Mode
is set as follows:
•
Run to Fill
: when the data logger is full (100%) it will stop logging
•
Circulate
: when the data logger is full, it will start from the beginning and overwrite the previous data (under
development).
The
Log 1/2 Interval
value determines how frequently the PQM logs each piece of data.
The total log size is approximately 64KB. The allotment of this memory can be varied between the two logs
to maximize the overall log time. Set the preference in
Size Determination
to let the PQM automatically opti-
mize the memory. If desired, the optimization can also be performed manually by the user.
In the
PARAMETER ASSIGNMENTS
settings, the
Log 1/2 Fill Time
values represent the amount of time the
data logger takes to fill to 100%. This time is dependent on the logging interval and the number of parame-
ters being logged.
Set the parameters to be logged by Log 1 and Log 2 by highlighting the selection in the
Assigned Parame-
ters
menu and checking the check box to assign it to the desired log.
