What types of HMI screens do I need?
An HMI project contains multiple types of HMI screens and each serves a different purpose. Use HMI screens to access and navigate the runtime application as well as provide high level and detailed views of plant activity.
Common types of HMI screens used in a runtime application include:.
HMI screen | Description |
---|---|
Log in | A Home screen that provides a way to log in. Assign different levels of access to the HMI screens within the application based on the credentials of the logged in user. |
Menu | An optional navigation screen that provides a high-level view of the screens and functional areas within the operator interface application. Navigate to progressively more detailed screens from a menu screen. For most applications, a menu screen is not required because View Designer creates a Navigation menu based on the organization of the contents of the Navigation Menu folder. The Navigation menu that appears at runtime is sufficient for all but very large applications. |
Alarm Summary | A high-level HMI screen that contains all the alarms for the controllers in the project. By default, each HMI project contains an Alarm Summary screen for monitoring and responding to alarms. Alarms are configured in Logix Designer . Alarms in Logix controllers appear on the Alarm Summary screen automatically at runtime. No configuration is required. Add an Alarm Summary to another screen to increase alarm visibility. |
Process overview | A high-level HMI screen that provides an overview of the process being controlled or monitored. The primary purpose of a process overview screen is to provide situational awareness, but it is not generally used to execute any controls. From these screens, navigate to additional screens that represent specific process areas. |
System status | A high-level HMI screen that provide one place to review the health and status of the processes and devices being controlled and monitored from the operator interface application. |
Process area | A mid-level HMI screen that provides information about a specific process area that is usually within the control of the user. Process area screens monitor the process and are often the main control interface for performing routine operational tasks. From these screens, navigate to detail displays related to the process being represented. |
Equipment overview | A mid-level HMI screen that provides information about a specific collection of equipment. An equipment overview screen is often used to view all equipment of a certain type. For example, create an equipment overview screen that shows all of the tanks. From this screen, select a specific tank and navigate to a tank detail screen within the collection. |
Equipment detail | A detailed HMI screen that contains all available information for a specific piece of equipment. For example, create a detail equipment screen for a specific tank or a specific pump. |
