Siemens SM2 monitoring system, U3585-J-Z125-8-76 1 manual Dynamic IO reconfiguration

SM2 in computer networks SM2 monitoring program

Restrictions for the computer network

1.The BS2000 /START-TASK-MEASUREMENT command can only be used on the local host.

2.Scroll commands

–Scrolling backward with “-” or “-R” is not supported across host boundaries; i.e. you cannot scroll back from the first report of one host to the last report of the previous host.

–You can only change to the first report of the previous host using the scroll command “-N” (node) (see page 152).

–You can only access the reports containing combined monitored data using “-N” while scrolling backward.

–The scroll command “--” always displays the first selected report.

3.The monitored values of the individual hosts are only output together if the time also corresponds. The system clocks on all hosts should be synchronized as far as possible and the same monitoring cycle must be set in SM2.

If no valid or new file exists, the following outputs are possible:

–SHOW-SELECTED-HOSTS statement

In the LAST BUFFER column, RSLT NOT VALID is output for the last monitored variable queried instead of the time.

–GLOBAL and NSM reports

In the column for the monitored variables, “∗∗∗” is output.

–SHARED PVS report

The message “SOME DATA MISSED” is output.

–Local reports

For local reports, the message “NO DATA FROM xyz” is output.

Dynamic IO reconfiguration

SM2 recognizes a dynamic IO reconfiguration and, if need be, automatically modifies the range of objects monitored. The monitoring programs CHANNEL-IO, SERVICETIME, SYSSTAT, TASK and NET-DEVICE and the monitoring process for CHANNEL/DEVICE are terminated internally and then restarted. As a result, monitored variables cannot be supplied for the most recent monitoring cycle.

Monitoring program definitions with wildcards *ALL, *DISK or *TAPE are re-interpreted.
