Thank you for your feedback
It's very difficult to give an exact time for how long the SiteManager can retain data.
It depends on a number of factors such as
- Number of sample points,
- size of the individual sample point,
- Sample rate
The store'n'forward will fill up with all samples during a connection loss to the cloud.
The S'n'F DB has a capacity of:
11xx/33xx: 80 Mbytes
15xx/35xx: 80 Mbytes or use of SD-card storage
(Performance may deteriorate due to the speed of the SD-card)
See DCM > Status for info on Ingoing rate, Outgoing rate & Store'n'forward usage.
This will give an estimate of the Store'n'forward timeframe at current samplerate.
See DCM > Status > details for info on your device.
The SampleDataType sizes
Type | Store'n'forward size |
“bool” (1 bit) | 1 byte |
“sbyte” (8 bit signed) | 1 byte |
“byte” (8 bit unsigned) | 1 byte |
“int16" (16 bit signed) | 2 bytes |
“uint16” (16 bit unsigned) | 2 bytes |
“int32" (32 signed) | 4 bytes |
“uint32” (32 bit unsigned) | 4 bytes |
“int64" (64 bit signed) | 8 bytes |
“uint64” (64 bit unsigned) | 8 bytes |
“float” (32 bit) | 4 bytes |
“double” (64 bit) | 8 bytes |
“string” (variable text up to 24575 bytes. Includes terminating NULL) | <=24575 bytes |
“data” (variable data up to 24575 bytes) | <=24575 bytes |
