Device status symbols
Device status is shown using symbols and text on the local display. Additionally, the symbol and
respective text message for each device status can be seen in remote engineering, asset
management or process control systems.
Messages are shown on the display.
● In the operation view, alarms are shown as a combination of symbol and text in the lower line
of the display. If several diagnostic messages are active at the same time, the most critical
is shown.
● In the alarm list view all active alarms are shown as a list. The alarm list combines a symbol,
text and an alarm ID number. The alarms are arranged according to the alarm ID numbers.
The alarm list view can also be accessed via parameter "Active diagnostic events" (menu
item 3.2.1).
● In the alarm history view the most recent alarms (up to 100) are listed. The alarm history log
can be viewed in parameter "Diagnostic log" (menu item 3.2.2). The alarm history log can
be reset in parameter "Clear diagnostic log" (menu item 3.2.3).
Device status characteristics
The following table provides possible cause of device status, and actions for the user or service.
The device provides two types of alarm formats; symbols used on the local display are based
on NAMUR status signals or Siemens standard alarm classes, selected in parameter "Status
icons" (menu item 2.8.11).
In SIMATIC PDM, symbols are based on Siemens standard alarm classes.
Note
Device status priority conflict - Namur vs Siemens standard
When more than one diagnostic event is active simultaneously, a conflict in priorities may arise.
In this case, the Namur symbol on the local display will differ from that shown in SIMATIC PDM.
Be aware of the priority for each device status, depending on the interface used.
