<h1>Turnout Control</h1>
|
|
Enter the accessory number or turnout system name for the accessory or turnout you wish to
|
|
control in the box to right of "turnout:". For example, entering 678 and by pressing either
|
|
the Thrown or Closed button, you should be able to change the state of accessory number 678
|
|
on the layout. Another example, a valid turnout system name for NCE could be NT456. Then by
|
|
pressing either the Thrown or Closed button, you should be able to change the state of
|
|
turnout or accessory number 456 on the layout. Another example, a valid turnout system name
|
|
could be IT123 which is internal turnout number 123. Pressing Thrown or Closed will only
|
|
change the state of the internal turnout and will not change a turnout on the layout. See
|
|
"<a href="../../../../html/doc/Technical/Names.shtml">Names</a>" under general help for more
|
|
information.

<h2>Turnout Control Buttons and Status</h2>
|
|
|
|
<dl>
|
|
<dt>current state:</dt>
|
|
|
|
<dd>Shows the current known state of the turnout. A turnout can have four states: unknown,
|
|
inconsistent, thrown, and closed. The unknown state is when JMRI doesn't know if the
|
|
turnout is thrown or closed. The inconsistent state is when a turnout on the layout is
|
|
commanded to throw or close but the feedback from the layout hasn't been received. Also
|
|
note that the inconsistent state can only occur if a turnout has feedback. The thrown and
|
|
closed states are what the JMRI program knows or believes is the state of the turnout.</dd>
|
|
|
|
<dt>feedback mode:</dt>
|
|
|
|
<dd>
|
|
Shows the turnout's feedback mode. Some of the available <a href="#Feedback">feedback</a>
|
|
modes are: DIRECT, DELAYED, ONE SENSOR, TWO SENSOR, and MONITORING. A turnout using
|
|
DIRECT mode doesn't have feedback from the layout. When a close or throw command is
|
|
executed the JMRI program assumes that the command always completes immediately. DELAYED
|
|
simulates the turnout operation taking a few seconds to complete. ONE SENSOR uses one
|
|
sensor on the layout to provide feedback on the state of the turnout. TWO SENSOR uses two
|
|
sensors for feedback, one for closed and one for thrown. MONITORING gets feedback from
|
|
the system by either listening to cab commands on the layout or polling the system for
|
|
turnout status. See the <a href=
|
|
"../../../../html/doc/Technical/TurnoutFeedback.shtml">turnout feedback page</a> for more
|
|
information.

<dt>Thrown</dt>

<dd>Push this button to throw the turnout.</dd>

Some turnouts can be locked. If the control button is grayed out, the lock feature isn't
|
|
available. See the <a href="#NCETurnoutLockFeature">NCE Turnout lock feature</a> below.

|
|
|
|
<h3 id="NCETurnoutLockFeature">NCE Turnout lock feature</h3>
|
|
|
|
<p>The turnout lock feature allows you to selectively disable accessory (turnouts) commands
|
|
from cabs. By locking a turnout, 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.</p>
|
|
|
|
<p>To use this feature you must select MONITORING as the feedback mode for the turnout and
|
|
the NCE command station must have the 2007 or newer EPROM.</p>
|
|
|
|
<p>To help you select a set of turnouts to lock, a route can be locked. All turnouts that are
|
|
being monitored by the JMRI program and are included in the route will be locked.</p>
