HMI

The HMI panel lets you enable GoHMI, choose which outputs you want to send to an HMI application, and launch with the HMI. You can also import and export an HMI.

You can send measurement data items (which contain both values and decisions), or values or decisions individually.

You configure the HMI on the Control > HMI page. For information on how to design an HMI app, see GoHMI and GoHMI Designer.

When you start HMI on a PC instance of GoPxL, a helper application (WebIQ Server) launches.

Data Items
Type	Description
Tool Output Items	This section contains the measurement decisions and values you added, which will be sent to the HMI. You can delete an item using the trashcan icon in its row. You can also use shortcut commands to delete all of the items, or specific categories of items. Show REST API Paths Toggles between showing the full internal path to an item, and an alias, which is a simplified representation of the item. In GoHMI Designer, you will see the REST API path for the items you add. Enabling this setting in GoPxL can help make it easier to find which item is which when developing an HMI. Show missing items If the source for an item is missing (that is, the tool providing the source has been removed in the job, or an output has been disabled), this option is displayed. Enabling it lists connections whose source can't be found. You can delete the missing connection, enable the source measurement in the tool if it has just been disabled. If the tool itself is missing and you add it again, you may still need to delete missing items on the HMI panel, and add them back again, to make sure you add the correct ones. .
User-Defined HMI Items	This section contains GoPxL REST API resources that are not tool outputs. They are defined and managed from within GoHMI Designer.
