MONITOR: Channel uses monitor (for ADEL threshold) and tries to save every received value.SCAN: Channel uses monitor (for ADEL threshold) and then saves the most recently received value every SCAN period.SCAN does not perform a get or get-callback every SCAN period, and it also doesn't save the time of when it was scanned.Instead, it would for example scan once every 5 minutes, and then write whatever the most recently received sample was .. if it changed.
