You can switch the assigned function definitions for a function. Only those function definitions are offered which match the correct number of connection points. The number of connection points of the new function definition must be the same or greater than those of the symbol used. For instance, it is possible to use the function definition "change-over contact" for an NO contact.

If the function should have fewer connection points than the symbol used, you need to switch the symbol. The new symbol then brings the new function with it.

You can also exchange function definitions using search and replace.
