On Advant Fieldbus 100, the EventSet communication is managed by the EVS(S) and EVS(R) elements. Each EVS(S) element can reference to up to 32 AIC, DIC channel elements and DIS65x elements and each EVS(R) can reference to up to 32 AIEV and DIEV channel elements. The EVS(R) element shall reference to the opposite EVS(S) element, this is done by specifying the station and the identity of the EVS(S) element.EventSet uses message transfer on Advant Fieldbus 100 and by this no configuration of CDPs has to be performed in the Communication Interface.Time-tagged events from an Advant Controller 110 are transferred to one or several event receivers over Advant Fieldbus 100. An event receiver can be: • An Advant Controller 100 Series • An Advant Controller 400 Series. • A personal computer running AC 100 OPC Server. The number of event receivers may be up to 10 for Advant Fieldbus 100.
The transfer of time-tagged events
over Advant Fieldbus 100 is configured by Event Set (EVS) elements. An Event Set element of type “send” (configured by data base element EVS(S)) groups a set of Event Channels for transmission of events. Each Event Set can handle up to 32 Event Channels of different types which can be mixed in arbitrary order. An EVS(S) element collects events from its referenced Event Channel elements and sends the events to the event receivers when those requests them. An Event Set of type “transit” (configured by data base EVS(T)) is used in Advant Controller 100 Series for transiting (receiving and sending) events from an EVS(S) element located on AF 100 Station. The Advant Controller 100 Series then acts as a transit station. The EVS(T) element shall refer to the opposite sending EVS(S) element. This is configured by specifying the identity of the EVS(S).
Event Transfer to AC 100 OPC Server and AdvaSoft for Windows
The event transfer to personal computers running AC 100 OPC Server and AdvaSoft for Windows is described in Advant OPC Server for Advant Fieldbus 100 User’s Guide (3BSE013896*) and Advant Fieldbus 100 Interface - AdvaSoft for Windows User’s Guide (3BSE006238*).One Advant Controller 100 Series can handle up to 16 Event Set elements EVS(S) or EVS(T). For DB elements EVS(S) the Event Channel elements are considered as event sources. For DB elements EVS(T) the referenced DB element EVS(S) is considered as event source.
