ActorClass¶
The opensource GridWorks Spaceheat Scada software is organized internally as a set of actors, with the prime actor being the SCADA itself. The SCADA must be able to deal with and process a wide variety of heating system arrangements. This is done in a Hardware Layout, which among other things organizes relevant physical devices in the heating system (thermal stores, circulator pumps, the heat pump, resistive heating elements, relays for heating elements). The primary objects in the Hardware Layout are space heat nodes, although the Hardware Layout also organizes and captures information about the specific hardware getting used (i.e. a serial number for a component, as well as its make/model).
All of the actors in the Spaceheat Scada are associated with space heat nodes. The Space heat Node’s ActorClass is an Actor enum used to determine the code used to run the actor. One node in the hardware layout will have an actor class of Actor.Scada (ActorClassEnumSymbol 6d37aa41): this is the SpaceHeat Node running the main SCADA code and supervising/managing all the other Actors.
