Digital Output Function:
A digital output can read out only two values which are associated with the Boolean values true and false; the output is either high = true or low= false.
The output value is the result of the evaluation of a Boolean expression, that here is set up using the two pull down-boxes and text input box.
The first box contains the same list of functions as available under Analogue Output Function, plus the ABBA function.
The second box contains a list of comparison operators.
The third box is used to type in a number. If the expression is true, the out will be high, and if the expression is false, the output will be low.
The selection “Any Beam Blocked in Area” has two values minimum and maximum. The output is high if one or more beams are broken with beam numbers that are larger than or equal to
Minimum and smaller than or equal to Maximum.
With the selection “Signal Alarm” the output is set high if the signal is not OK.
Set Digital Output
Marking the checkbox
Force Set Enable
disables the
Digital Output Function
and enables the user to set the digital output high by selecting
Output Forced High
or low by selecting
Output Forced
Low
. The function is primarily intended for test purposes.
Output delay:
On-delay specify the time between the expression becomes true and the output is switched accordingly. Off-delay specify the time between the expression becomes false and the output
is switched. On-delay and off-delay is selectable between 0 and 10 s.
