SM2 operation Statements for nonprivileged users

A3 Monitoring cycle shorter than output

cycle

Monitored data is lost because the

central buffer of the monitoring task is

cleared faster than the data is output

during the output cycle.

B Controlled mode

If the user does not succeed in having all the reports of a monitoring cycle output

before the central buffer is ﬁlled again by the monitoring tasks, some monitoring cycles

will be lost. When a report is requested again, the ﬁrst report of the new monitoring

cycle is output.

Note

The ACTIVITY, CHANNEL, andDEVICE

reports are requested in this example.

The data of the monitoring cycles marked

with * was overwritten in the central buffer

before the user requested all the reports

of the monitoring cycle shown ﬁrst.
