Using CAAPE Graphics6.8.3. Adding Components to the SystemOnce you’ve created a system, you can create and add the additional components itneeds in any order. You do not have to finish editing a component before you can add itto a system; you can create the component, add it to the system and then edit itscontents later.Components are added to specific boards in the hardware of the system. Before addingcomponents you must edit the hardware to add the boards involved. Open the systemthat contains the hardware by double clicking on it in the Project View. The hardware isopened for editing, and the adding components function is enabled. If the hardwarecomponent was opened by double clicking on it in the Component View, addingcomponents is not allowed, components can only be added in the context of a system.The possible linkages between boards and components are:• Logic Components− CPU/PD, CPU II, VSP, CSEX, NVSP and CenTraCode II-s CPU boards requirea logic component to specify the application logic they execute. Open the board,go to its Board tab, and go to the Logic section on the tab. Click the Logic buttonto add a logic component.• Message Components− CSEX boards that communicate with a CPU/PD or CPU II board, or NVSPboards that communicate with a VSP board, require a VPI-to-CSEX messagecomponent to specify their DPRAM-based communications. Open the board, goto its Board tab, and go to the VPI Communications Message section on the tab.Click the Messages button to add a message component.− TWC and NVTWC boards require Train-to-Wayside message components tospecify the messages they send and receive. Open the board and go to theSerial Messages section. Click the Messages button to add messagecomponents.− CSEX, NVSP and CenTraCode II -s CPU boards require non-vital serialmessage components to specify the messages they send and receive. Open theboard, go to the desired Serial Port tab, and go to the Serial Messages sectionon the tab. Click the Messages button to add message components. Dependingon how the component is used, the Source or Destination column of themessage data is used. You can link a single component as both a control(received message) and an indication (transmitted message).P2512A, Rev. Oct/09 6–45 Alstom Signaling Inc.
