10.3 Safety messages for SINAMICS S120
10.3.1 General information
Note
In the HMI environment, faults and alarms are displayed specifying a six--digit
number that always starts with 2. For example, this means that F01600 is then
called 201600. In this Chapter, faults and alarms are described with numbers from
the SINAMICS environment.
In the HMI environment, faults and alarms are treated like alarms.
