Triggered Datalogging:
In addition to timed datalogging, a datalog record can be created when an event signal goes TRUE. The event signal is supplied by an ISaGRAF program running in the station. See Logging data upon an event signal for more information.
Controlled Datalogging:
Timed datalogging can be enabled or disabled by specifying a Log/stop signal. This can be a discrete output register from a computer or other device. The timed datalogging will only happen when the Log/stop signal is TRUE.
