3.2.46 DYT_ - Delay Timer
DYT_
function blocks perform either an ON or OFF
output delay as determined by the TYPE configuration
parameter.
ON Delay - When input P is low (0), output O1 is low.
If P goes high (1), the elapsed timer starts and sets O1
high upon reaching the DLY TIME, provided P is still
high.
OFF Delay - When input P is high (1) the output is
high. If P goes low (0), the elapsed timer starts and sets
O1 low upon reaching the DLY TIME, provided P is
still low.
In firmware 1.30 and higher, the DLY TIME is
adjustable over the full range of the display, which is 0.00000 to 999999. In earlier versions, the minimum time
setting is 0.1. If the delay time is set to less than the scan time of the station, the delay time will equal the scan time.
Output ET (elapsed time) will ramp from 0.0 to the value of DLY TIME and remain there until P resets the output.
Output RT (remaining time) equals DLY TIME - ET.
POWER UP - During a warm or a hot start, with PU LAST set to YES, the block will initialize with the
input/output states and elapsed time in effect at the instant power down occurred. A cold start, with PU LAST set to
NO, will initialize the input/output states and elapsed time to 0.
