11.6 Logical Functions and
Timers [600]
With the Comparators, Logic Functions and Timers,
conditional signals can be programmed for control or
signalling features. This gives you the ability to compare
different signals and values in order to generate
monitoring/controlling features.
11.6.1 Comparators [610]
The comparators available make it possible to monitor
different internal signals and values, and visualize via
digital output or a contact, when a specific value or
status is reached or established.
There are 2 analogue comparators that compare any
available analogue value (including the analogue reference
inputs) with two adjustable constants.
For the two analogue comparators two different constants
are available, Level HI and Level LO. With these
two levels, it is possible to create a clear hysteresis for
the analogue comparator between setting and resetting
the comparator output. This function gives a clear
difference in switching levels, which lets the process
adapt until a certain action is started. With such a hysteresis,
even an instable analogue signal can be monitored
without getting a nervous comparator signal.
Another function is to get a clear indication that a certain
situation has occurred; the comparator can latch
by set Level LO to a higher value than Level HI.
There are 2 digital comparators that compare any
available digital signal.
The output signals of these comparators can be logically
tied together to yield a logical output signal.
All the output signals can be programmed to the digital
or relay outputs or used as a source for the virtual
connections [560].
Analogue Comparator 1 Value [611]
Selection of the analogue value for Analogue Comparator
1 (CA1).
Analogue comparator 1 compares the selectable analogue
value in menu [611] with the constant Level HI in
menu [612] and constant Level LO in menu [613].
When the value exceeds the upper limit level high, the
output signal CA1 becomes high and !A1 low, see Fig.
86. When the value then decreases below the lower
limit, the output signal CA1 becomes low and !A1
high.
The output signal can be programmed as a virtual
connection source and to the digital or relay outputs.
