Getting precise time of pulse edge.
Is there a way to get precise time of a rising edge of the pulse? I'm using LS Electric XEM-DN32H2. After reading the documentation, I'm under the impression that the current time value is refreshed only once per scan. I would like to get more accurate time stamp. Is it possible? Is there a code example, preferably with Structured Text?
the manual list the processing speed of the cpu as 40nS per cycle but it also says the triacs need a min of 100uS pulse width to sense the sensor signal so i would say at least 200uS cycle but you would need a oscilloscope if you need precise readings
How do I read the time stamp of the rising edge of the pulse? I can't find any clock functions other than low resolution DATERD and DATERDP. Where is it in the manual?
Do you have to use the RTC? If not will the high speed counter function work for you?
I need the timestamp of the pulse. Does the counter provide it? Just pulse counting is not sufficient.
High speed counter does not give a timestamp.
