The Operator Interface - HMI

The CMXä Operator Interface System can have up to sixteen multigraphic high-performance user consoles in VGA, SVGA, or HVGA display mode. Legacy terminals such as VT100 or PC CGA are also supported.

CMXä ’s versatile operator interface provides standard and configurable displays throughout the System and also gives system developers the options and tools they need to design custom graphic and user display.

Standard Displays

CMX’s use of standard and configurable displays completely eliminates the necessity of having to design and build user displays, thereby greatly reducing development time and its associated costs. The standard interface structure maintains a functional commonality between screens across the System, meaning that an Operator only needs to learn one set of operating procedures. Context-sensitive on-line help screens also greatly simplify learning. Other standard displays include:

• Login Display for security access
• Main Menu Display for report and display access
• Tag Display for individual Tag information and sub-displays
• Alltags Display and Tags Display for directory information
• Unit Display and Unit Sub-display for Unit status and control
• Alarm Display for user configured System abnormality
• Messages Display for Unit and System information
• Config Display for System status and diagnostic information
• Tune Display for trending loop parameter while changing tuning constants
• Tabular Continuous History Display
• Graphical Continuous History Display

CMXä further simplifies system development by providing a set of configuration tools that the user can easily access from within the display interface while CMXä is operating. These include:

• Menu Builder for configuring user-specific login menus
• Menus for configuring user-specific operating display menus
• Profiles for configuring displays that group up to twenty-four Tags at once
• Plots for configuring realtime line graphs for trending
• Alias to create keyboard “macros”
• Report to configure on-line reports from the Unit or Continuous History
• First Out Annunciator for displaying custom alarm screens
• Custom Help Displays
• SPC Chart Display for optimizing process variables

On-line Help

Context sensitive help is available from every standard display in the System. User help screens can be easily added.

The online display Editors for Menus, Profiles, Plots, Aliases, and Reports provide a field for entering the name a help display. Help displays can be created and formatted using a set of “dot” formatting commands and any standard ASCII text editor.

System Security

As a function of its Security System, the user is required to furnish a user name whenever the System is started. The user name tells the System the individual’s access level. This controls which CMXä functions the user can and cannot utilize. Up to 100 levels can be categorized, from look-only, to Operator, Application Engineer, and System Developer, to keep unauthorized personnel from critical system parameters and regulate their access to CMXä operations.

SPC Chart Builder

The SPC Chart Builder was developed to enable Engineers to use Statistical Process Control (SPC) charting with the CMXä Display Program.

SPC Chart Builder supports SPC X-bar charting by furnishing a manual data entry form and a separate display for defining charting parameters.

Data can be presented as a graphical chart or in a tabular format.
