5.2 Sensor Data Logging
The sc1000 controller provides a data log for each sensor.
The sc100 provides three data logs (one for each sensor and one for calculated values).
The data logs store the measurement data at selected intervals. The event log stores a
variety of events that occur on the devices such as configuration changes, alarms, and
warning conditions. The data logs are stored in a packed binary format and the event logs
are stored in a CSV format. The logs can be downloaded through the digital network port,
service port, or the IrDA port. DataCom is needed for downloading logs to a computer.
