DISPLAY BLOCK
2.2 DISPLAY BLOCK (DISP)
The display block is used to assign display resources and keyboard actions to one user
display. Display resources are identified as shown below. Keyboard actions include pressing,
holding and releasing one of the eight available keys (Alarm through the down arrow -
∇ ). In
its simplest form, the display block connects variable data for presentation as values on lines
or bars. These values can be formatted and identified with engineering units or other labels.
More advanced functions are accomplished using the display script language. A display
script is an event driven set of statements used to respond to keyboard actions and other
events. The state of the Display block is defined within the script (there can be multiple
states) and uses the State Table block and the Tune List block for valid state lists and tune
lists. Multiple display blocks can be configured for an instrument and each requires that it be
listed in the Display Interface block to be accessible. Display blocks are only executed when
the instrument is in RUN. In all other states, only the device displays will be available.
