# Use Parameter List

Assign a digital tag. The application reads the value of the tag to determine whether a parameter file or a parameter list will be used to provide parameters to the display when it opens at run time. If the tag value is 0, or if this connection is not assigned, the display will open using the parameter file specified in the Parameter File connection. If the tag value is 1, the display will open using the tags defined in the Parameter Tag # connections.

If neither this connection nor the Parameter File connection is assigned, but one or more of the Parameter Tag # connections are assigned, the display will open using the tags assigned to the Parameter Tag # connections.

Only 10 parameter tags can be assigned in this editor. If a display needs more than 10 parameters, use the Parameter File connection.
