Using CAAPE GraphicsNon-Vital Serial and Vital Serial message components can be used in various ways torepresent a pair of messages, two ends of the same message, or one end of a singlemessage:• You can use a single component to represent a paired set of one source and onedestination message on the same board / port. The transmitted message isrepresented by the component’s Source column and the received message isrepresented by its Destination column.• You can share a single component between systems to represent both sides of asingle message that is passed between the systems. The sending system uses thecomponent’s Source column and the receiving system uses its Destination column.• You can use separate components for all source and destination messages. In thiscase, each component has either the Source or the Destination column filleddepending on whether the message it represents is received or transmitted.In Figure 6–10 the Destination column is filled and the variables are therefore used foran incoming Vital serial message.Figure 6–10.
