7.3.8.14 PDE (ON delay)
Brief description
BOOL-type timer with ON delay
Mode of operation
The rising edge of a pulse at input I sets output Q to 1 after pulse delay time T.
Output Q become 0 when I is 0.
If the duration of input pulse I is less than pulse delay time T, Q remains 0.
If time T is so long that the maximum value that can be displayed internally (T/ta as 32 bit
value, where ta = sampling time) is exceeded, the maximum value is set (e.g. when ta = 1
ms, approx. 50 days).
