III-7.2 PEAK ( peak value memory (No. 31))
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!
