9.1.3.2 „Safety at Work“ Monitor Diagnosis
Function: 02
16
Because the „Safety at Work“ monitor can make more than 32 Byte diagnosis da-
ta, these must be read with several mailbox calls. The second request byte decla-
res the start index in the field of the daignosis data.
If the start index ist 0, new data is fetched from the monitor, otherwise the function
responses out of the memory, through which the data can be read consistently.
