5.6.1 Switching hardware write protection on and off
A jumper on the I/O board provides the means of switching hardware write protection on or off.
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.
Remove the I/O board → ä 72.
2.
3. Configure hardware write protection and simulation mode appropriately using the jumpers
(see graphic).
4. Installation of the I/O board is the reverse of the removal procedure.

1 Jumper for enabling/disabling write protection:
1.1 Write protection enabled = it is not possible to write-access device functions via the FF interface
1.2 Write protection disabled (factory setting) = it is possible to write-access the device functions via the FF interface
2 Jumper for simulation mode:
2.1 Simulation mode enabled (factory setting) = simulation in the Analog Input Function Block and in the Discrete
Output Function Block is possible
2.2 Simulation mode disabled = simulation in the Analog Input Function Block and in the Discrete Output Function
Block is not possible
LED (light emitting diode):
– Continuously lit → Ready (no communication via FF active)
– Not lit → Not ready for operation
– Flashes slowly → Ready (communication via FF active)
– Flashes quickly → Device error present (error message type "fault message") → ä 58
