If
events are enabled using the FMS service “Alter–Event–Condition–Moni-
toring”,
an open link (MSZY_SI or MSAZ_SI) has been parameterized
and
if there is any change in a diagnostics message,
the ET 200U(DP Standard/FMS) uses the “Event–Notification” to transmit a
low–priority message together with the diagnostics data to the FMS master.
The diagnostics message thus transmitted
is sent only once and
need not be acknowledged with the FMS service “Acknowledge–Event–
Notification”.
The “diagnostics event” object has the following structure.
