than the Trigger Data Signal Deadband
compared to its value when the previous sample
was taken.
e. Sample Interval to set the interval from 2 seconds to 3 hours (10800 seconds).
f. Trigger Data Signal is the Data Signal which triggers sampling, when the Sampling Method
is set to Sample on Trigger Data Signal Change
g. Trigger Data Signal Deadband determines how much the Trigger Data Signal has to
change before a new sample is taken.
h. Capture When True to control whether data is captured continuously or only under certain
conditions.

:
If the
Capture When True
value goes unknown, the Datalog
will ignore it. If the Datalog is in the waiting state (or the sampling state), when the
Capture When True
value goes unknown, the Datalog will stay in the waiting (or sampling)
state it was already in.
4. From the Data Signals table, click Add Data Signal to add the number of data signals you need.
Up to 20 signals can be created.
5. From the Configuration table, click the edit icon to setup the following information for each Data
Signal :
a. Name to give the signal a name;
b. Description if you want to document what the signal means or how its value should be inter -
preted;
c. Field to bring up the field picker and select the ADIO input or other value you want to monitor.

You cannot leave data signal fields unknown. You cannot select
state or boolean values for data signals.
6. Run the Start Capture command.
If all of the Data Signals are not configured when the Start Capture button is pressed, the capture
will still start, but an entry is made in the event log to indicate a Data Signal is not configured.
You can configure the
Datalog to run at certain times of day, or to stop after a certain time or
number of samples, by configuring a boolean Custom Data and then configuring Capture When
True to use it.
If you change the Data Signals , Sampling Method , Trigger Data Signal , Trigger Data Signal
Deadband or Number Of Samples To Capture , that will make the old data is incompatible with
the new data. The old data will be deleted when you run the Start Capture command.
Transferring Datalogs Configuration to other Controllers
By importing and exporting a configuration file, some datalogs configuration can be transferred to a new
controller. A datalog sources information from data signals coming from various physical measurements
on its system, and the data signal will only transfer to a new controller if that measurement also exists
on the new system.
For example, the Total Load Current is an attribute of the DC System. A datalog measuring the Total
Load Current will only transfer to the new controller if it has a DC System in its inventory.
However, signals such as a rectifier's Ambient Temperature measurement are attributes of that specific
rectifier. If a configuration file is exported from one controller and imported onto another, the Ambient
Temperature data signal will not import, and it will raise an Invalid Config Ignored event. The new recti -
fier will need to be re-configured to the new controller.
