Work in Simple mode

In Simple mode, the work with the HMI Editor is similar to work with the previous version of the HMI Editor.

The Simple mode creates textual definition for a PLC, and textual and graphical definition for a terminal.

A textual template for a PLC is used to create a menu for the LCD display which is part of the PLC, i.e.for platforms mark120, mark125, mark220, and mark320.

This LCD menu is able to access the variables which are part of the PLC where the LCD is. The engineering can be done by three ways:

• Manual editing, same as in the old HMI Editor version. Textual HMI objects are inserted to the template (Analogue indicator, Digital setter etc.), and these objects are bound to variables. The editor only displays variables which belong to the particular PLC. A more detailed description can be found at the Textual template for a PLC - LCD menu  page.

• Tagging of selected variables in the FUPLA Editor. Tag a variable or function block as HMI Import. It is possible to predefine a format for the LCD menu and other properties for the tagged variables. Later, when the LCD menu is created, automatic import can be used and the predefined properties are imported into the menu definition. A more detailed description can be found at the Textual template for a PLC - LCD menu  page.

• Select the variables in the dialog for adding a variable into the editor. The editor selects then the default object type for a variable. In the dialog there are all elements belonging to the particular PLC to select from.

A textual template for a terminal is used to create a menu for devices which do not contain a PLC, and which can link to one or more PLCs over the network: HT102, HT200, or the Mervis Menu Reader application.

The menu engineering is similar to this for the PLC. To start engineering, define a Terminal device in the system structure first. A Terminal contains a Terminal Channel which specifies the PLCs the terminal is able to communicate with. The terminal template then will have access to the variables which belong to the selected PLCs. Steps to create textual template are described in chapter Textual template for terminal

A graphical terminal template defines graphic panels for the HT200 terminal or for the Mervis Visual application.

To start engineering, a Terminal  must be defined first. The engineering follows in the graphic editor. The resulting menu can be tested in the Mervis isual emulator, which is part of the Mervis IDE.Steps to create graphical template are described in chapter Graphical template for terminal
