Constant as an integer input
How to set and connect the input
Option 1
• Scroll to the input selection parameter of the block and switch to edit mode
(Enter).
• Select C in the inversion field (double arrow and arrow keys). The appearance of
the row changes. The rest of the line is now a constant field.
• Give the constant value to the constant field (double arrow and arrow keys).
• Accept by Enter.
The figure below shows the panel display when the input I1 selection parameter is in
edit mode and the constant field is visible. The constant may have a value from
-32768 to 32767. The constant cannot be changed while the adaptive program is
running.
Option 2
• Set the constant to one of the parameters reserved for the constants.
• Connect the constant value to a block as usual by the input selection parameter.
The constants can be changed while the adaptive program is running. They may
have values from –8388608…8388607.
