<p>After clicking on the "Add..." button below the <a href=
|
|
"../beantable/SignalMastLogicTable.shtml">Signal Mast Logic Table</a>, the following window
|
|
appears:</p>
|
|
<a href="../beantable/images/SignalMastLogicAdd.png"><img src=

"Signal Head Logic Add window"></a>
|
|
<p>The first thing you must do when creating a Signal Mast Logic is to select the Source
|
|
Signal Mast followed by the Destination Signal Mast. The source signal mast is the one which
|
|
you wish to control and set the appearances on. The destination signal mast is the next
|
|
signal mast down the line. The Appearance of the destination Signal Mast along with the state
|
|
of the Turnouts and Blocks that you check on this screen will have a direct effect on the
|
|
Appearance of the source signal mast.<br>
|
|
If you are not using the Layout Editor, then <em>no</em> validation is performed of the
|
|
source and destination Signal Masts. If the Layout Editor is being used, then the system will
|
|
try and determine if the destination Signal Mast is reachable from the source mast.</p>
|
|
|
|
<p>The check box "Use Layout Editor Paths" allows you to get JMRI to automatically generate
|
|
the required Blocks, Turnouts and Signal Masts, along with their states, that are located
|
|
between the source and destination Signal Masts.<br>
|
|
On selecting "Use Layout Editor Paths", two further check boxes will appear: "Use Turnout
|
|
Details From Layout Editor" and "Use Block Details From Layout Editor". Selecting either of
|
|
these will determine what information from the Layout Editor is used when the system
|
|
automatically generates the route.<br>
|
|
The automatically generated information is not saved with the panel file, but it is generated
|
|
each time the layout panel is opened.<br>
|
|
If the information on the layout editor panel is edited, the change is not reflected in the
|
|
Signal Mast Logic; you will need to store the panel, close JMRI and re-open the panel for the
|
|
Signal Mast Logic to be updated.</p>
|
|
|
|
<p>The "Allow The Logic to Automatically Determine Conflicting SignalMasts" option tries to
|
|
determine which Signal Masts could possibly cause a conflicting route if they were not set to
|
|
danger.</p>
|
|
|
|
<p>The "Lock Turnouts when Signal Mast Logic is active" feature allows you to selectively
|
|
disable accessory (turnout) commands from cabs and/or locally-wired pushbuttons. When
|
|
selected, JMRI disables pushbuttons by sending pushbutton disable commands to the Turnout
|
|
decoders when the route is locked, and enables the pushbuttons when the route is unlocked.
|
|
When locking a Turnout from cab commands, the JMRI program will monitor the Turnout's
|
|
accessory address and if it detects a change command from a cab, will cancel the command
|
|
immediately by sending out the opposite command to the Turnout. All Turnouts that are being
|
|
monitored by the JMRI program and are included in the route will be locked.</p>
|
|
|
|
<p>The "Show"" radio buttons allow you to show all or only the selected Turnouts, Sensors,
|
|
Blocks or Signal Masts that are part of this Signal Mast Logic.</p>
|
|
|
|
<p>There are four tabs below the "Show" buttons, each containing the details of Blocks,
|
|
Turnouts, Sensors and Signalmasts that make up the Signal Mast Logic for this Source Mast. In
|
|
each of these tabs, there is an editable table that allows you to manually select which
|
|
item(s) should be included in the Signal Mast Logic and the state which each item should be
|
|
in.<br>
|
|
Below that is a second table that shows the automatically generated items (except in the
|
|
sensor tab). Manually entered items over-ride the automatically generated items, therefore if
|
|
you wish to over-ride any item in automatically generated list then in the manual table
|
|
select the corresponding item and set the state. Click the "Include" box in any of the tables
|
|
to add the desired item to your Signal Mast Logic. Next to the "Include" box is the State
|
|
option which that item must be in for the Source Signal Mast to come active. For example, if
|
|
you wish a Turnout to be in a Thrown state to trigger the Signal Mast Logic, then select
|
|
"Thrown" in the drop down box. If you wish to over-ride a turnout that was automatically
|
|
included, and you don't care what state it is set to, select "Any State" from the drop down
|
|
box.</p>
|
|
|
|
<p>Clicking on the "Update Signal Mast Logic" button will add or update this Signal Mast
|
|
Logic to the system. Apply will do that too, and close the Edit pane. Once a new Logic is
|
|
added, the tables holding the automatically generated data will be re-populated.</p>
