To change the value, perform the following steps:
1. Double-click on the face of the function block you want to
change.
2. Select the Parameters tab.
3. Locate the value that you want to change (values that can be
changed are white). Enter the new value in the box.

The new value takes immediate effect. If you are changing a
preset, remember to Save the configuration the next time you
exit from the Function Block Editor.

Once you go on line and Logic Enable is set to ON, online animation
starts. The status of the I/O can be seen in the Function Block Editor
schematic. Note that in the online animation mode, you cannot edit
instructions.
There are a few remote cases with analog values that result in an error
(for example, divide by zero). In these cases, the error value
expression has the following format:
