Prevention of creation of IO-Link events
The NFC lock using the extended device access locks parameter has a higher priority than
the NFC PIN. That means that this lock also cannot be bypassed by entering a PIN.
6.1.3.2
PIN code for NFC write protection
The writing of changed parameters via NFC can be controlled using a separate PIN code. When
delivered, the PIN code is 000 and a lock is therefore not active. The NFC PIN code can be changed
using IO-Link.
When a PIN code is set between 001 and 999, the valid PIN must be entered for every subsequent
write process using a mobile NFC device so that the SCTMi accepts the changes.
