PrintingA simple text printout of the entire hardware component can be obtained by going toFile | Print on the main menu.6.4. EDITING MESSAGE COMPONENTSMessage components are used to represent the various messages sent or received byhardware boards. Representing messages as components allows the same messagedata to be reused in multiple places in the project.Each message type has a specific editing screen which is used when editing themessage data. Message editing consists of specifying any options such as binaryaddress and defining the variable names that make up the message bits.The Message Wizard can also be used to enter variables that make up a message. Seethe section on graphical systems for details.6.4.1. Source and Destination NamesIn many cases it is possible to enter both source and destination variable names in thesame screen. “Source” and “Destination” names are from the point of view of the boardthat sends or receives the data: source refers to data sent by the board, and destinationrefers to data received by the board. "Special Messages" - Non-Vital Serial or Train-to-Wayside messages containing protocol status and receive / transmit control flags - arealways considered destination data and their variables should always be placed in theDestination column.P2512A, Rev.
