Conditional State Variables and Actions List

Available State Variables

State variables that are currently available for use in Conditionals are listed below, along with information on each. State variables must always evaluate to either true or false. The condition resulting in true is given for each. If the condition is not met, the state variable evaluates to false. When a Logix is active, the states of entities (sensor, turnout, light, etc.) specified in state variables in its Conditionals are monitored, unless the Triggers Calculation checkbox of the state variable is unchecked. A calculation of all Conditionals in the Logix is triggered when any monitored state changes as noted below (if not obvious).

  • Sensor
    • Sensor Active: Evaluates to true if the state of the specified sensor is active.
    • Sensor Inactive: Evaluates to true if the state of the specified sensor is inactive.
  • Turnout
    • Turnout Thrown: Evaluates to true if the known state of the specified turnout is thrown.
    • Turnout Closed: Evaluates to true if the known state of the specified turnout is closed.
  • Light
    • Light On: Evaluates to true if the specified light is on.
    • Light Off: Evaluates to true if the specified light is off.
  • Signal Head
    • Signal Head Appearance equals: Evaluates to true if the appearance of the specified signal head matches the selected Variable Aspect (appearance).
    • Signal Head Lit: Evaluates to true if the specified signal head is lit.
    • Signal Head Held: Evaluates to true if the specified signal head is being held.
  • Signal Mast
    • Signal Mast Aspect Equals: Evaluates to true if the aspect of the specified signal mast equals the aspect specified in the state variable. Calculation is triggered when the aspect of the signal mast changes.
    • Signal Mast Lit: Evaluates to true if the specified signal mast is Lit.
    • Signal Mast Held: Evaluates to true if the specified signal mast is being held.
  • Memory
    • Memory-Value Compare: Compares the value saved in the specified memory to the value specified in the state variable using a specified comparison operator. Evaluates to true if the comparison is true. There are 5 comparison operators that may be used for the evaluation:
      • "less than"
      • "less than or equal"
      • "equals"
      • "greater than or equal"
      • "greater than"
      Calculation is triggered when the monitored memory value changes so that the comparison to the specified value changes.
    • Memory-Memory Compare: Compares the value saved in one specified memory to the value saved in a second memory location. There are 5 comparison operators that may be used for the evaluation:
      • "less than"
      • "less than or equal"
      • "equals"
      • "greater than or equal"
      • "greater than"
      Calculation is triggered when one of the monitored memory values changes so that the comparison value changes.
  • Conditional
    • Conditional True: Evaluates to true if the state of the specified Conditional is true.
    • Conditional False: Evaluates to true if the state of the specified Conditional is false.
  • Warrant
    • Route Free: Evaluates to true when the route is available.
    • Route Set: Evaluates to true when the route has bee set.
    • Route Allocated: Evaluates to true when the route has been allocated.
    • Route Occupied: Evaluates to true when the route has been occupied.
    • Train Running: Evaluates to true< when a train is running./li>
  • Fast Clock
    • Fast Clock Range: Evaluates to true if the current fast clock time is between the begin time and end time specified for the range. Times must be specified in hh:mm format, where hh is hours and mm is minutes, relative to a 24-hour clock. Calculation is triggered when the fast clock time enters the range and when the fast clock time exits the range.
  • Occupancy Block
    • Occupied: Evaluates to true when the block is occupied.
    • Power Error: Evaluates to true when a power error has occurred.
    • Out Of Service: Evaluates to true when a block is out of service.
    • Dark: Evaluates to true when a block is to dark.
    • Path Occupied: Evaluates to true when a path is occupied
    • Unoccupied: Evaluates to true when a path is not occupied.
    • Allocated: Evaluates to true when the block is allocated.
  • Entry Exit
    • Active: Evaluates to true when the Entry/Exit is active.
    • Inactive: Evaluates to true when the Entry/Exit is not active.

Available Actions

Actions that are currently available for use in Conditionals are listed below along with information on each:

  • Sensor
    • Set Sensor: Sets the specified sensor to the chosen state. Specify the sensor to set by entering its name. Specify the state to set by choosing Active or Inactive in the popup menu.
    • Delayed Set Sensor: Sets the specified sensor to the chosen state after waiting for a specified number of seconds. Specify the sensor to set by entering its name. Specify the state to set by choosing Active or Inactive in the popup menu. Specify the number of seconds to delay before setting the sensor by entering a number in the right-most field. If this Conditional is already waiting to set this sensor, this action is ignored, and the previous action continues as originally scheduled.(see also Reset Delayed Set Sensor below.)

This action is the same as Delayed Set Sensor, except if this Conditional is already actively waiting to set the specified sensor, the previous wait is cancelled, and a new wait period is started. In effect, the wait time is restarted. The sensor is not set until the most recent wait period expires.
    • Cancel Timers for Sensor: Cancels all timers waiting to set the specified sensor in all Conditionals in all Logixs. Specify the sensor by entering its name. The sensor is not set; all active delayed actions for setting the specified sensor are cancelled without setting the sensor.

    • Delayed Set Turnout: Sets the specified turnout to the chosen state after waiting for a specified number of seconds. Specify the turnout to set by entering its name. Specify the state to set by choosing Closed or Thrown in the popup menu. Specify the number of seconds to delay before setting the turnout by entering a number in the right-most field. If this Conditional is already waiting to set this turnout, this action is ignored, and the previous action continues as originally scheduled.(see also Reset Delayed Set Turnout below.)
    • Turnout Lock: Locks or unlocks a turnout. Enter the name for the turnout, and choose the operation from the popup menu. Note: To control the type of turnout lock go to the Turnout Table and select the Lock Mode.
