5. 5 Hardware settings
5.5.1 Switching the write protection and simulation mode on and off
Hardware write protection and simulation mode (for AI and DO function block)
can be switched on and off by means of DIP switches on the I/O board or the amplifier board. When
write protection is active, parameters cannot be modified. The current write protection status is
displayed in the WRITE_LOCK parameter (Resource BlockPage 81).
1. Unscrew the cover of the electronics compartment from the transmitter housing.
2. Remove the local display module (a) from the retaining rails (b) and refit onto right retaining
rail with the left side (this secures the local display module).
3. Fold up the plastic cover (c).
4. Configure the hardware write protection and simulation mode accordingly with the aid of the
DIP switches (Fig. 24).
5. Installation is the reverse of the removal procedure.

e LED (light emitting diode):
– Lit continuously = ready for operation
– Not lit = not ready for operation
– Flashing = system or process error present

f DIP switch for hardware write protection
– A = write protection switched off (DIP switch to the front = factory setting)
 Access to device parameters via
FOUNDATION Fieldbus interface possible
– B = write protection switched on (DIP switch to the rear)
 Access to device parameters via FOUNDATION
Fieldbus interface not possible
g DIP switch for simulation mode:
– C = DIP switches 1 to 9 = not assigned
– D = DIP switch 10 = simulation mode 
OFF (factory setting) = simulation mode possible in the Analog Input Function Block or in the Discrete Output
Function Block 
ON = simulation mode not possible in the Analog Input Function Block or in the Discrete Output Function Block
