15.2 PEAK ( peak value memory )
Maximum input value x
max
and minimum input value x
min
are determined, stored and output at
Max
and
Min
. With
the stop input set to 1, the extreme values determined last remain unchanged.
If the
reset
input is set to 1, the extreme value memory and any applied
stop
command are cancelled. (x
max
and x
min
are
set to the instantaneous x1 value and follow input x1, until the
reset
input returns to 0.)
Unused inputs are interpreted as 0 or logic 0.
The function has a ‘memory’. This means: after power-on, it continues operating with the Min- and Max values which
existed at power-off, provided that the RAM data are still unchanged.
No parameters!
Inputs/outputs
Digital inputs
stop
With the stop input set to 1, instantaneous values Max and Min are unchanged.
reset
The reset input deletes the
Min
and
Max
values.
Analog inputs
x1
Process value, the min and max values of which are output.
Analog outputs
