Pause

Data storage can be paused by a digital signal. During long-term recordings, it might be useful to pause the data storage yet without closing the data file. For example, this could be the case in shut-down times of machines during a work shift when no measured data arise, but the data file is intended to cover the entire shift.

While a data storage is paused, all measured values in the data file are replaced with invalid values, which will be displayed as a gap in ibaAnalyzer. Signals with INT, WORD and BYTE data types are saved to the data file as 16 bit integer values. Since there is no invalid bit for these data types in the data file, these values will be replaced with 0.

The period of the ibaPDA server acquisition loop is equal to the smallest common multiple of all module time bases, but no less than 50 ms.

The pause signal is evaluated only once per acquisition loop. The signal is 1 (TRUE) if it remains 1 (TRUE) for the whole duration of the acquisition loop period. It is 0 (FALSE) as soon as 1 sample is 0 (FALSE) during the period of the acquisition loop.

This means that the data storage will be paused a certain time x after the rising edge of the pause signal. The time x is between 0 and the acquisition loop period.

This also means that the data storage will be resumed a certain time x before the falling edge of the pause signal.

The data storage status tree shows a pause icon when the recording is paused.
