Switching hardware write protection on and off
Two jumpers on the I/O board provide the means of activating or deactivating hardware write
protection and simulation mode (for AI and DO function block).
#
Warning!
Risk of electric shock. Exposed components carry dangerous voltages. Make sure that the power
supply is switched off before you remove the cover of the electronics compartment.
1.
Switch off power supply.
2.
Remove the I/O board
3.
Configure the hardware write protection and simulation mode accordingly with the aid of the
jumpers (see Figure).
4.
Installation of the I/O board is the reverse of the removal procedure.

1
Jumper for switching on/off the write protection:
1.1
Write protection switched off (default value) = write access to device functions via FF interface is possible
1.2
Write protection switched on (default value) = write access to device functions via FF interface is not possible
2
Jumper for simulation mode:
2.1
Simulation mode enabled (default value) = simulation in Analog Input function block or in Discrete Output function
block is possible
2.2
Simulation mode disabled = simulation in Analog Input function block or in Discrete Output function block is not
possible
