Process Tags

Process tags define all the data points that are common to all the units associated with a process class. Each automatically defined process tag generates a set of unit tags for each member in the process class. For example, if there are three units in a process class and one process tag is entered, three unit tags are created: one for each unit in the process class. Each of these unit tags correspond to a specific address in a control system. Process tags are indirectly associated to the control system by way of the unit tags that they create.

Process tags have an abstract nature; that is, they are not directly associated with the control system. Process tags represent a set of unit tags. Process tags become unit tags when a batch is executed in a process. Process tags can be used as part of recipe transition logic.
