Running Applications
4–2
Application screens can have a variety of appearances. The DTAM Plus can
display seven types of screens.
• Menu and Sub-Menu Screens
• Security Screens
• Data Display Screens
• Data Entry Screens
• Recipe Screens
• Bargraph Screens
• Alarm Screens
The DTAM Plus provides several options for changing the screen displays:
• Screen links
• Advisor option
Screen Links
Use the [NEXT] and [PREV] keys to step backward and forward through this
sequence.
Main Menu and Sub-Menu screens list screens that can be accessed by
pressing the assigned numeric key [1] through [8]. A typical Main Menu
screen provides links to individual screens or sub-menus:
1 Pump
2 Tank Stat
3 Mixer Stat
4 Recipe
In the example above, pressing [2] at the Main Menu displays the status of a
holding tank. Pressing [4] displays a Sub-Menu of the recipe screen options.
Advisor Option
Applications can allow screen changes that are controlled by an SLC or PLC
logic controller. When the logic controller writes a valid screen number to a
specified Advisor register, the corresponding screen is displayed. The
controller can initiate a screen change based upon a variety of inputs to the
controller. For example, a pressure limit switch can be used to initiate the
display of a pressure control screen. It is the responsibility of the application
designer to document when and what screen changes may occur.
