Display masks
Display masks are the D2000 system objects. They are defined for particular process alarm states of objects of I/O tag, Eval tag and Switch type. They are used to define a text, that will be displayed in the Alarm list window (the Event description column) in the process D2000 HI after changing the status of the object's process alarm into the corresponding status. A display mask is defined by a text that can also contain format masks.
There is a predefined group of display masks in the D2000 system. The masks are used for displaying various operations of the D2000 system (e.g. the display mask SM._Start_Systemu is used when the D2000 system is starting).
