i’m not finding it anywhere. See JMRI's SignalMastFollower.py script. It uses: self.outSignal.setAspect(self.inSignal.getAspect()) This is what that script needs to do to make one signal mast reflect another signal mast's aspect. There are a number of requirements that make this a usable solution. One limitation is that the signal referred to in "self.outSignal" does NOT implement Signal Mast Logic! One can instead allow a script to "selectively-override" a mast's SML-defined Aspect information. One can implement Signal Mast Logic for the signal mast, and implement a "listener" to trigger a script bit that can determine when the aspect is not appropriate, and "override" the Aspect. Note that the mast might possibly show the original Aspect, briefly before showing the "overridden" Aspect. To avoid this, one _could_ implement something more like a "signalMastFollower.py" script, with optional Aspect-overriding, and displaying the overridden Aspect on the physical mast. This would probably not be appropriate for any kind of JMRI "automation", though, unless your automation mechanism does not rely on the overridden Aspect, or unless some other "hack" is used. (It _might_ be appropriate to create a new "signal mast" type for the "Prototype Signaling System", rather than hacking a Jython script, though! That might be a better solution than hacking the Aspect via Jython...)

Re: Best Command Station to use with Decoder Pro
Heath,

?Not a command station, but my PR4 will reliably read all the CV's on a LokSound in about 20-25 minutes. That's not as fast as the LokProgrammer, because as Ross pointed out, the LokProgrammer uses a proprietary method. But it is quicker than at least some command stations.

What I did before the PR4, and still do to a lesser extent, is open the CV's tab and tell it to read the page. Then I find something else to busy myself with until it finishes.

Re: Best Command Station to use with Decoder Pro
Standard DCC is a one-way protocol: [NMRA] standard DCC command stations can only send messages to DCC decoders and DCC decoders cannot send messages to [NMRA] standard DCC command stations (yes, there is RailCom, but that is something different). Normally, DCC decoder CVs cannot be directly "read". Reading CVs is done via a trick. The DCC command station asks if a bit is a one or zero and the decoder does (or does not) run the motor a little if the bit is a one and the command station detects the slight current draw. To read a CV byte, the DCC command station asks 8 times, once for each bit in the byte. This process takes time. All [NMRA] standard DCC command stations do this the same way, so all take the same amount of time. At Wed, 19 Mar 2025 17:17:52 -0700 "Human[c]ity Junction" <heath@...> wrote:

Re: Best Command Station to use with Decoder Pro
Heath,

The NMRA method of ‘reading’ CV values is the JMRI read time ‘weak link.’
?
The LokProgrammer uses a proprietary method for quickly reading and writing CV values.? ?However, LokProgrammer isn’t compatible with JMRI.
?
FWIW – you can read the CV values with LokProgrammer, then export them to a file that can be imported into JMRI.? ?

Re: Block occupancy without resistive wheelsets
Yes, there is a"software" solution ... rather two solutions now.
Steve_G added a "ghost" block to be connected to a turnout.
When both real detectors on either side of the turnout are active, the "ghost" is active.
?
I haven't used the "ghost" as my layout predates that feature.
I summarize my "software" approach in my blog ?...

Re: How to edit script, re-exec without restarting?
#scripting
I don't know the best way to remove old listeners, but I have tested this and it seems to work.
sen = sensors.getSensor('LNT-Jython')
# See if the listener has been created.
try:
??? appListener
except NameError:
??? appListener = None
if appListener:
??? # remove listener from objects
??? sen.removePropertyChangeListener(appListener)
appListener = SomeListenerClass()
print 'Listener = {}'.format(appListener)
# add new listener to objects
sen.addPropertyChangeListener(appListener)
Jython variables that are not within a class are global for the duration of the JMRI session.
The first run will create the listener. ?Subsequent runs will remove the old listener and add a new one.

Subject: [jmriusers] How to edit script, re-exec without restarting? #scripting
Date: Wednesday, March 19, 2025 11:06 AM
I'm working on a script to facilitate virtual block handling (time before unoccupied, etc) by considering time entered and exited and block length. Since every car being pulled draws power I can estimate how long it will be in a virtual block (assuming same speed).
?
The script is loaded at startup and adds property change listeners.
?
Since I'm learning JMRI I have to make incremental changes and every time I have to restart since the old listener is still active.
?
Maybe I could save my chained listener objects in a memory and check if it's there if I re-execute the script but wanted to check with experts first.
Is there any advice for avoiding a restart?

Re: The future of control and automation - thoughts?
With tiny cameras in our phones, and AI, and ever higher integration, someday soon it should be possible to have a camera in every loco, and have it run on clear track, obey signals if they are used, and stop short of other trains or end of track.
I enjoy running my trains manually, but my loop to loop railroad doesn't lend itself to having a train or two run in the background while I switch (shunt) cars or change motive power. The railroad is much more enjoyable when more than one train runs, in my opinion. But, I make mistakes when I try to run two or three at a time by myself.

Re: How to edit script, re-exec without restarting?

stevemac,

The document at provided two implementations of () and one of those might be used as your script closes down for the next trial run.
?
If your development is still at the stage of unexpected termination, this idea might not be very useful.
?
Suggestions for all beginning Jython programmers: Keep the Console window open and at least partially visible and put in a lot of print or log statements.

Step 1: ?Use the Layout Editor "Tools -> Check" menu items to clean up the non-contiguous blocks.
Step 2: ?Run the GrandReset.py script. ?This will delete all of the transits, sections, SML and block paths. ?After doing a Store and re-start, use "Auto Generate Signaling Pairs" in the Signal Mast Logic table menu to create new SML.

Hi All,
?
I have added the panel file ?exhib.xml to the David Smith folder in ProblemsBeingWorked?
There are some issues with some of the signal masts.
Could someone please advise what the problem may be ?
?
Buffer masts Mst_Buff_SdS4, Mst_Buff_SdS5, Mst_Buff_SdS6 are set to Unknown
?
Mst_SE3, Mst_SE2, Mst_SW3e, Mst_SW3f, Mst_W4 signal logic does not see other masts correctly
( I am aware that I could fix the issues by manually editing the signal logic but would prefer not to )
?
Can I also please ask, if ?I add a mast that is not visible on the panel, is there a way to see or edit it afterwards ?
?
Also, can I ask why all of the signal heads appear in the Turnouts table ?
?
Thanks
Dave

Re: The future of control and automation - thoughts?
Speaking of WS2812 3-color LED controller IC's, RR-CirKits offers an LCC-based signal controller for their "Simple Serial?Signal Bus" that controls signal LEDs using these inexpensive IC's!
?
Even if signals & switch controllers were wireless, you'd still have to wire power to them.
?
And while controlling track switches via the DCC track bus, using stationary decoders, simplifies and saves wiring, running a train against such a switch would short out both the track and the means by which to rectify the problem from the throttle/panel.

Re: The future of control and automation - thoughts?
Regarding Bluetooth control:? is it possible to control more than 1 locomotive at the same time from a single throttle over Bluetooth with any of the current systems?? I don't have any experience with any of them.
?
Also, I'd just like to add that while some people certainly aren't interested in automatic operations - and that's fine - other people do like automation, and that's fine too.? I personally loved the challenge of setting up my layout so it could be operated fully manually, semi-automatically, or fully automatically, and enjoy using it in any of those modes depending on how I feel at the time.? That's the beauty of "My Railroad, My Rules", and the great thing about the flexibility of JMRI.

Re: Block occupancy without resistive wheelsets
Roger,
With turnouts in a separate block, and not even very long trains, you'd see the occupancy indicator of the turnout go off while both blocks at either side remain on - unless there's added logic.
Wouter
My mainline freights always have a last car with a FRED which is drawing power. A lighted caboose would be the same. So the occupancy light trips as soon as the loco enters, and doesn't release until the last car leaves. No need for resistor wheels on intermediate rolling stock.
|
Re: The future of control and automation - thoughts?
But also remember that a lot of us like to drive the trains and operate the layout entirely manually. Automation holds absolutely no attention from me.??
Same here. OperationsPro is my sole use of JMRI these days. (And occasionally DecoderPro, but mostly LokProgrammer)
?
So in that vein, I've begun to wonder if I could use AI (namely, v0.dev) to write code modifications for OpsPro to mold it more to my niche-prototype likings. Would love to have suggestions on how specifically to do so if anyone has any, as I'm willing to learn but would prefer not to if I can help it. Am the wrong kind of engineer by trade!
?
More to OP's original question, I think Bluetooth is the future (especially for loco-to-loco comms) but the current offerings (namely Blunami & RailPro) are neither mature nor featured enough to get me to switch from DCC.
