# Data Logging Sample Interval

Channel data for some or all channels may be sampled at this configured interval. Sampled values are date/time stamped and temporarily stored in the RTU flash memory until downloaded into a Log File or cleared.

When “Data Samples” is selected for logging, the base time and frequency control the data-sampling interval. In the example above, the base time is 00:00:00 (midnight). The frequency is once per hour. With these settings, data sampling will occur once an hour, on the hour.

The data sampling frequency seconds are rounded up to the nearest even integer. Valid range is 10-58 seconds.

Note: If you are using data logging, there are several different factors and settings involved, so it is important that you also review Remote Data Logging.
