"System alarms" tab: System alarms can only be viewed but not edited. To edit these alarms, you must navigate to
the device view ("Go to device" menu command), where you can modify the system diagnostics alarms in the In-
"Type alarms" area:
This is where the type alarms created in a function block with the "Program_Alarm" instruction are displayed. Type
alarms serves as templates for instance alarms (
④).
All the inputs you make for the type alarm are automatically included in the instance alarms derived from it.
You can find more information on type alarms in the STEP 7 online help under "Alarm types and alarms".
"Instance alarms" area:
When you assign an instance DB to the message block (for example, call in an OB, FB, FC), instance alarms are
automatically generated based on the template of the type alarm and alarm numbers are assigned.
You can modify the instance alarms for specific instances.
You can find more information on instance alarms in the STEP 7 online help under "Alarm types and alarms".
