PID C0F4: SECURITY DELAY
Delay time for sensor evaluation
The sensor delay time can be activated to delay sensor rela-
ted action. Thus it will be possible to trigger a relay and to di-
sable the output again as soon as the sensor is triggered.
This allows to create applications like automatic filling stations
(relay activated and de-activated as soon as sensor reports fil-
ling level) or flame detectors (process started but halted if
sensor not in range after delay time).
Delay time is defined in increments of 25ms. Thus the total
time can be adjusted from 0...6,3 seconds.
Parameter:
<Slot number> <DELAY> [Byte]
where:
Slot number = 0001
Slot number = 0002
Slot number = FFFF
DELAY = 00
(timecount * 25ms)
Example: The safety supervision for relay 2 shall be engaged
after 2 seconds:
SET PID C0F4:
Calculation: 2 seconds is 80x 25ms, 80(dec) is 50 hex ($50). Most RDM
controllers require values to be entered in hex format.
