descma Posts: 5 Rating: (0)	Hi, I have a MP377 who archive alarms and historical trending on a SD card from a CPU412. WhenI go on the archive alarms at the first time that goes fast. If I go before on an historical trending and afterto the archieve alarm that take 10 minutes to have the archive alarms. After that if I go never on a historical trending that take 5s ifI go again on the archive alarms. How can I decrease the time to wait the arrival of historian alarms after going to the historical trending ? Sorry for my bad english but I'm talking frensh.
