Using the Graphical Simulator10.11.5.1. Device Display ImagesThe image that a given device element displays on the track plan screen depends on itsuser-selected properties and on its current run-time state. The state of the devicedepends on the values of its associated variables and on any run-time device modesselected by the user.When a track plan is first opened in Run mode, some devices may display an Invalidimage: a red track segment, a color light or SA signal device that is crossed out in red,or a signal device that shows red cross-hatching. Devices are considered invalid if theyhave no assigned variables, or if they have assigned variables that cannot be found bythe simulator. Reasons for an invalid device may include:• No variable assigned at all.• Misspelled application or variable name, or a variable that once existed but wasremoved from the application.• Array index: index specified for a non-array variable, no index or bad index specifiedfor an array variable.10.11.5.2. Setting Track OccupancyTrack occupancy can be set just by clicking on the track segment. Note that, if multipletrack segments are all assigned the same input variable, clicking on one of thesegments is enough to change the state of all of them. The input variable changecaused by clicking on one segment is transmitted to the rest of the segments as well.10.11.5.3. Setting Device ModesSpecial modes such as Out of Correspondence or Filament Broken are available forsome device types. To set such modes, select them from the device's popup menu.10.11.5.4. Device TimingSwitch and SA signal devices mimic the throw time of their real-life counterparts. Settinga drive variable True in the simulator therefore does not cause the corresponding deviceposition variable to be set True immediately. The simulator must be cycled for asufficient amount of time for the transition to occur.P2512A, Rev. Oct/09 10–45 Alstom Signaling Inc.
