7.5.3.6 Output

Icon: Menu: InsertWOutput Keyboard: -

Use this command to add an additional assignment to an already existing assignment.

This function assists the generation of so-called assignment combs, i.e. the assignment of the value

currently assigned to the line to several variables.

• If the selected intersection is over an assignment or the directly preceding output, another

assignment will be added behind those already in existence.

• If the selected intersection is directly in front an assignment, an assignment will be inserted in

front of this assignment.

The inserted output is pre-assigned with ”???”.

• Click this text to change it to the required variable. Alternatively, use the Help Manager (<F2>)

to do so.

Note!

This command is also available in the ladder diagram editor.
