Sig Limit
A0034298-EN
This unit can be used to limit the value of the input port In . If In is less than Min and the minimum
limit is activated by the Boolean input port MinEn , the output is set to Min . If In is greater than Max
and the maximum limit is activated by the Boolean input port MaxEn , the output is set to Max .

The limitation is performed in the largest numeric data type of all the output ports that are
connected to the input ports
In , Min and Max of the unit. These input ports and the output port
adopt this data type.

Sig Smooth
A0034299-EN
This unit is used to smooth a signal. If the value of the input port In changes, the value of the output
port will be approximated to this new value using an exponential function.
The value of the input port
TUp (32-bit unsigned integer) refers to the time (in ms) that is needed to
reach the new value if the old value is less than the new value.
The value of the input port
TDown (32-bit unsigned integer) refers to the time (in ms) that is needed
to reach the new value if the old value is greater than the new value.

If the Boolean input port Force is set, the value of the input port In is copied immediately to the output
port.
The smoothing is performed in the numeric data type of the output port that is connected to the input
port
In of the unit. The input port In and the output port adopt this data type.

Sig Track
A0034305
This unit is used to limit the gradient of a signal. If the value of the input port In changes, the value of
the output port follows this new value using a linear function.
The value of the input port
GradUp defines the maximum slope of this linear function per second if the
new value is greater than the old value. The value of the input port GradDown defines the maximum
slope of this linear function per second if the new value is less than the old value. Both gradients must
be positive numbers.

If the Boolean input port Force is set, the value of the input port In is copied immediately to the output
port.
The Boolean input port
En can be used to enable the unit. If the value is 0 , the output port is always 0 .
The tracking is performed in the largest numeric data type of all the output ports that are connected
to the input ports
In , GradUp or GradDown . These input ports and the output port adopt this data type.
