Data
Logging
iNetGrow gives you two distinct
ways to log data. Each method has
its own advantages. Moreover, you
may use both methods in your system.
Also known as PC data logging,
this method allows you to log all system variables on the PC. The PC must be connected to your LAN
and must be left on. Use the PC
Options dialog to specify how often you want the data to be logged. The entire system data may be logged as
often as every minute to once an hour.
Data
Logging on the Controllers
Each controller on your LAN has
the capability to log data from its own modules. Use the Setup Network dialog to select and configure the
controller for data logging. In
this method, you may specify which named system variables you would like to
log. This method is convenient in
cases where few variables are to be logged, or when a PC is not present on the
LAN at all times. The data logged
on the controllers may then be viewed or retrieved using the History dialog.
