A.2.14 Soft starter diagnostics
For access to the soft starter diagnostics only read access (r) is possible via
Function Codes 01, 02, 03 and 04.
Note
Message type of the soft starter diagnostics
In the "Soft starter diagnostics" data table, diagnostic messages may be present twice. In
this case, the message type (error (ER), warning (MT) or other message type (-)) determines
which bit is activated.
