so that you can look up where a particular signal
has beeen “generated”.
HPT_Y07
Calculated
Name .
VX Selection
Measured
1
2
If the setting value of parameter »Name . VX
Selection« is set to “Measured”, then output 1 is
active and output 2 is inactive.
If the setting value of parameter »Name . VX
Selection« is set to “Calculated”, then output 1 is
inactive and output 2 is active.
HPT_Y08
Name .
ExBlo1
No assignment
1..n, Assignment List
The setting value of parameter »Name .
ExBlo1« is not a choice from a simple, 󰊎xed
selection list, but it is another parameter
(usually a binary output signal) that is assigned
from a parameter list.
This means that the setting parameter assumes
the value of the assigned parameter. In case of a
binary output signal, for example, it means that
the parameter »Name . ExBlo1« is active
whenever the assigned output signal is active.
If no signal has been assigned then the output is
always inactive (and only the “No assignment”
box, which is not connected in this example,
would be active).
HPT_Y09
IA
I<
%(V2/V1) > 40%
%(V2/V1)
Two types of comparator (“Schmitt triggers”):
Top row: If the analog input value (here: the
voltage ratio %(V2/V1)) is greater than the
speci󰊎ed threshold (here: 0.4) then the output
becomes active (=logical “1”).
Bottom row: This type has the opposite
functionality: If the analog value IA is below the
threshold (here: the setting value of parameter
I<«) then the output becomes active.
E_E0A
t-Off Delay
─────────────
t-On Delay
t
on
t
off
Timer stage: If the input becomes active, then
the output becomes active after the time t
on
(setting value of »t-On Delay«) has elapsed
(switch-on delay).
If the input becomes inactive again, then the
output signal becomes inactive after the other
speci󰊎ed duration has elapsed (switch-o󰊍 delay
t
o󰊍
, setting value of »t-O󰅠 Delay«).
HPT_YX0
78 .
Trip duration time
t
Hold time: This is a pulse which is triggered by
the input (and in this case, the pulse duration is
settable via parameter).
