CUSTOM PROPERTIES FOR AUTOMATION CONTROL

摘要

The present invention provides central management of custom properties, including graphic facets, for an industrial control system. Standards for the custom properties are centrally developed and are then propagated to projects. Even after one or more projects have been developed, the custom property can be centrally changed, and the change can be propagated to all existing projects to override previous properties in the projects. With central management of the graphic, the inner functionality can be abstracted from the location where the graphic will be used. In some embodiments, a custom property is given a default value. That default value may be overridden in a particular project or at particular time, but the property can always revert back to the set default. Some custom properties may be "locked" to prevent user modification, and some properties may be set to be invisible to the end user.
