Siemens SM2 monitoring system, U3585-J-Z125-8-76 1 manual 154

Statements for nonprivileged users SM2 operation

Depending on the output mode and the length of the two cycles, the following situations are possible:

A Automatic output mode

A1 Monitoring cycle and output cycle have the same length

Monitored data acquisition and report output take place at intervals of the same length

If the system load is high, the time required for output to the terminal may be considerably increased; this may result in the data of a particular monitoring cycle being skipped during output.

		intervalle

A2 Monitoring cycle longer than output cycle

After all reports for a monitoring cycle have been output, SM2 waits until data of the next monitoring cycle becomes available.

This causes the output interval to be extended.
