5.6 PROFIBUS DP hardware settings
5.6.1 Configuring the write protection
A jumper on the I/O board provides the means of switching hardware write protection on or off.
When hardware write protection is switched on, it is
not possible to write to the device functions
via PROFIBUS (acyclic data transmission, e.g. via the operating program "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.
2. Remove the I/O board.
3. Configure the hardware write protection accordingly with the aid of the jumpers (see Figure).
4. Installation is the reverse of the removal procedure.
