Inhibiting operation 

Positioner operation can be inhibited completely or partially via the digital input and the FUNCTION parameter in parameter group 10 (DIG_IN (digital input)). This allows the user to prevent or restrict operating actions of unauthorized personnel as desired. When operation is disabled in this way, the key symbol is indicated in the display. 

The following levels of configuration locks are possible:

Inhibiting all local operating functions No local operating actions can be executed. Both the operating level and the configuration level are locked. Remote operation and setting of parameters via a PC is still possible. Inhibiting local operation and remote configuration It is not possible to operate or configure the positioner locally or configure it using a PC.
