Paragraph: Table 14
Category: Issue for edition 2 of this part
Let’s asume that nominal frequency of the system is 50 Hz and sampling rate is 80 samples per nominal period. That means that sampling rate is 4000 samples per second or 0,00025 seconds per sample.
According to standard SmpRate is amount of samples (default per nominal period, see SmpMod) and it’s an integer.
If we select SmpMod to be “samples per second” should SmpRate equal 4000?
How should we treat SmpRate if SmpMod is “seconds per sample”? We cannot enter 0,00025 because type of SmpRate is integer.
In your example, just don't use "seconds per sample".
This mode is only intended for very low sampling rate sensors.
