Application Scenarios

BOD Card Configuration

  1. Using a CDI configuration tool, open the BOD Card(s) segment and update as follows:
  2. Configure the card’s information section and the communications COMM BUSand COMM ADDR fields to match the corresponding selections on the BOD Card (PCB).
  3. Refer to the Line tab for the line connected to the track block. The default value for the ON Event ID will be used for setting up the signal masts aspect. If available in the configuration tool, use the Copy button to copy the Event ID to the clipboard for use later.

Signal Mast Configuration

  1. Using a CDI configuration tool, open the Signal Masts segment and update as follows:

  2. Click on the Card 1 and Mast 1 tabs. For this example, the card 1 is connected to a Signal Masts Breakout Board connected to the mast.

  3. Update the Card Information Configuration and Card Communications Configuration fields.

Field Value Description
Rules Configuration Rule 2(tab) Configure the the 2nd rule (for normal speed)
Rule Name 29-Clear Selection identifies the rule being configured
Track Speed Clear Selection identifies the speed for the track.
Aspect Indicator G/R - Proceed on Mainline Selection identifies the aspect to be shown for the desired speed.
Set Aspect Event ID The Event ID to set the aspect. Used with Logics and Conditionals for setting the aspect.
Aspect Set Event ID Not used.
Aspect Cleared Event ID Not used.
Lamps Configuration Lamp 1 (tab) Selection identifies configuration for the first lamp.
Lamp Selection LED_1 Select the LED number associated with the lamp associated the wired mast.
Lamp Phase Steady Selection indicates the lamp is to remain steadyly lite.
Lamp Brightness 50 Selection indicates the lamp is be set a 50% brightness, a good starting point.
Lamp Glow Effect Duration Selection identifies a normal glow of the lamp.

Logics and Conditionals Configuration

For this simple signaling example, we can use just one Logic statement to configure the mast to show the correct aspects for stop or clear based on the track occupancy downstream.

The logic statement looks like this: IF (Block is Occupied) THEN Set Aspect to Stop ELSE Set Aspect to Clear.

  • Since only one logic statement is needed, for the Logic Group indicate that the logic is that last one for the group.
  • For the conditional, define use a single Condition (V1) configured to check for the ‘occupied’ Event ID what would be produced by the BOD Card’s configuration for the connected track block that is downstream of the mast.
  • For the True action, configure the Event ID for setting the Mast Stop aspect, which was previously defined by configuring the Masts Rule 1.
  • For the Flase action, configure the Event ID for setting the Mast Clear aspect, which was previously defined by configuring the Masts Rule 2.
  • For both actions, configure the action to be performed immediately and to stop processing after the Event ID is sent.

Below are the detailed steps for configuring this example:

  1. Using a CDI configuration tool, open the Logics and Conditionals segment and update as follows:
  2. Click on the Logic 1 tab.
  3. Set the group processing information and define the conditional as follow:

Field Value Description
Description Main Line Signal Control A label describing the purpose of the logic, such as managing the main line signal.
Group Functionality of Logic Last... Setting indicates that this is the ‘Last’ logic statement in a group. In this example, a group of only 1 logic. All other logics in the table will default to Blocked and will be ignored (not used).
Condition 1 Configuration   The following fields define the logic conditional’s first condition, Condition 1.
Condition 1 Source Event ID Identifies the source for the condition. This Logic’s conditional uses anEvent ID (block’s occupied status) to determine its state for true/false. The Event ID from the BOD Card configuration is specified below.
Condition’s Trigger When Condition's Event ID or Speed Changes Selection indicates that the condition’s is triggered by a change in the Event ID which occurs with the BOD Card detects a track occupancy change.
Condition’s Track Circuit Speed This is only used condition’s souce is a Track Circuit (Speed from Track Circuit #).
Condition’s True Event ID Enter an Event ID that triggers this condition to be true. Use the On Event ID value configured for the BOD Card’s block that is produced when the downstream block is occupied. If possible, simply copy and paste the Event ID found in the BOD Card Line associated with the block.
Condition’s False Event ID Enter an Event ID that triggers this Condition to be false. Use the Off Event ID value configured for the BOD Card’s block that is produced when the downstream block is cleared (not occupied). If possible, simply copy and paste the Event ID found in the BOD Card Line associated with the block.
Logic Operations Condition 1 Only Indicates how the Logic Conditional is be processed using only Condition 1.

Configuration of Condition 2 is not required since the conditional only needs one Condition defined.

  1. Configure how the Logic is too be processed when the conditional is true and when it is false. In both case, since there is only one logic in the group the processing should exit the group and that both actions should be processed immediately.

Field Value Description
Logic’s Flow When True Send then Exit Group Setting indicates that processing of the logic group terminates after handling the logic’s true condition. No other logics are necessary for setting the signal mast aspects.
Logic’s Flow When False Send then Exit Group Setting indicates that processing of the logics group terminates after handling the logic’s false condition. No other logics are necessary for setting the signal mast aspects.
Action’s Time Delay 0 Setting indicates that the logic’s actions should take place immediately, causing the aspect to be set immediately.
Action’s Time Interval Not used since the Timing is set to 0.
Action Retriggerable No Setting indicates the logic’s actions can NOT be retriggered again after completion.

  1. Configure two actions, one for when the conditional is true (track block is occupied) and one when the conditional is false. In both cases, Event IDs are sent to set the appropriate aspect for the mast.

Field Value Description
Action(s) Configuration Action 1 (tab) The first action configured will set the mast aspect for the Rule Name 0-Stop.
Action Trigger Immediately if True Selection indicates the action is to occur immediately if the conditional is True (i.e. the block is occupied). The actual action produces the following Event ID.
Action Event ID 05.01.01.01.5C.65.06.03 Enter the Set Aspect Event ID from Mast 1, Rule 1 which is configured for 0-Stop rule with an aspect for a Stop speed.
Action(s) Configuration Action 2 (tab) The second action configured will set the mast aspect for the Rule Name 29-Clear.
Action Trigger Immediately if False Selection indicates the action is to occur immediately if the conditional is False (i.e. the block is unoccupied). The actual action produces the following Event ID.
Action Event ID 05.01.01.01.5C.65.06.02 Enter the Set Aspect Event ID from Mast 1, Rule 2 which is configured for 29-Clear rule with an aspect for Normal speed.
