Manual
Version 1.0.0
9.12.2 SNMP V3
In SNMP version 3, exchanging messages is user-related. Each device, that
knows the passwords set via WBM, may read or write values from the fieldbus
coupler.
In SNMP v3, user data from SNMP messages can also be transmitted in
encoded form. This is why SNMP v3 is often used in safety-related networks.
Via this WBM page "SNMP V3" two independent SNMPV3 users can be defined
and activated (User 1 and User 2).
