2) If PV is not a constant.
3) If "PV A: / PV B:" is a constant.
4) The choices offered depend on the choice made in "PV A: / PV B:" above.
TYPE: Choose the function.
NAME: Rename the function chosen. See section 8.4 Entering text. This name appears in the view asso-
ciated with this function in Process level.
STATE: Used to activate (choose "ON") or deactivate (choose "OFF") the selected function.

device automatically deactivates the function. For example, if a function F1 uses a function F2 and F2 has
been deactivated, either manually or automatically, the function F1 will be deactivated.
PV A (OR PV B): A and B can be constants, measured physical parameters, results of other active con-
figured functions, values entered by the user (PVC), values coming from a PLC (PVN), ... (see section 15).
