Is there a way to set up the Trend and Alarm recording data to save to the SD card instead of internal memory?
If not is there any concern that large amounts of write cycles (particularly from the Trend Recorder) may cause issues with the internal memory?
When you are talking for PLC alarms, here are the settings:
Select (1) AlarmStorage
(2) You can provide a subfolder of the PLC folder on internal storage where the SQLITE DB with alarm is stored
(3) You can limit the DB by "number of records" or "max. storage size"
To view the files:
Run PLC program and create some alarms
Right click "Device..." in project tree & select "Communication settings"
Select tab "Files" (1), press Refresh icon (2)
Double click folder "myAlarms" to display its content
Trend recording has the same limit settings as the alarms
