Configuring the write protection

A jumper on the I/O board provides the means of switching hardware write protection on or off.
When the hardware write protection is switched on, it is not possible to write to the device
parameters via PROFIBUS (cyclic data transmission, e.g. via FieldCare).
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. → Page 152
2.
3. Configure the hardware write protection accordingly with the aid of the jumpers (see Figure).
4. Installation is the reverse of the removal procedure.

1 Jumper for switching write protection on and off
1.1 Write protection switched off (factory setting) = it is possible to write to the device parameters via PROFIBUS
(acyclic data transmission, e.g. via FieldCare).
1.2 Write protection switched on = it is not possible to write to the device parameters via PROFIBUS
(acyclic data transmission, e.g. via FieldCare)
