Thanks!? I opened the xml file in wordpad, searched for 301, added?IX where appropriate.? Now it opens normally without errors.? Also tables can now be opened from PanelPro menu.

THANK YOU!!!!

By the way, after opening the panel file, and dismissing the errors, there is nothing in the logix table.? But I guess that is expected since it stopped loading once it hit the bad entry.

When you say "post the file" I assumed you meant my panel file.? it has been posted to the same folder.

Bob,

You have some invalid Logix system names. There appears to be at least one that is missing the IX prefix (301).

The Logix loading stopped with 301 which means the related conditionals for the remaining Logix definitions have no parent Logix.

If you are comfortable editing XML the fix is fairly easy. You will need to fix both the 301 Logix and the 301 Conditionals. Otherwise, you can upload the panel xml file and I could fix it.

Both sets of problems (4.8 and 4.12) are probably coming from the same place, which is that somehow there’s a Conditional (part of Logix) in the file with a bad name, and the program is having trouble connecting everything up. The relevant parts of the message log aren’t really very clear and concise, but that’s what they mean. See below.

The problem is probably the conditional named 301C1 which doesn’t have a leading “IX”, i.e. should be called IX301C1.

If you post the file, I can take a look at it.

Downloaded and installed 4.12.? Tables now open.? But I think I now have a bigger problem? I'm getting a java error when I open my panel, didn't get any error with 4.8 version.? Here is the error message ...

You’re probably getting that message because the thread has _already_ stopped. If handle returns False (which is 0), that’s it, the thread is stopped.

One last error happens when I close the window: ERROR - stop with currentThread null! This must be my use of dispose and stop. Would you recommend I do something differently on closing the window?

“Open Logix Table” in Preferences normally does open without the table selector: It’s opening the _Logix_ Table, not the Tables window. You can have it open other ones too if you’d like.

But the real question is why normal operation isn’t working. That’s not all that large a panel file, particularly for that machine.

There have been a number of changes since JMRI 4.8. A good first step would be update to 4.12.

Hello,

Is there a limit to the size that a panel file can get before strange things start happening? I've done a lot in PanelPro and my XML file is now at 1053 KB. Everything seems to work well, except I cannot open any of the tables from the PanelPro menu. I suspect it is a memory issue, but want to be sure before I act on it. Adding "Open Logix Table" to the start up in preferences allows the table to open, but without the list of other tables on the left, so if I need to navigate between tables I need to change the preferences and restart JMRI each time. Not convenient!

I run JMRI on a dedicated PC, meaning I use this PC for nothing else. It's running Windows 10 with Intel Pentium CPU 4405U @ 2.10GHz and 4.00 GB RAM (3.88 usable). I'm running JMRI 4.8 +Rbe0ff15, Java version 1.8.0_181. When I check Task Manager the Processes tab shows Java using 248.5 MB of memory. The Performance tab shows a total of 2.3 of 3.9 GB memory in use, Committed 3.1/4.6 GB, Cached 1.6 GB, Paged Pool 231 MB, and Non-paged Pool 406 MB (not that any of that means anything to me except that there seems to be 1.6 GB of memory free). The session log in my JMRI \log folder show nothing out of the ordinary, no errors.

As always, any help will be greatly appreciated.

I fully appreciate Bob's point about the nature and origins of JMRI. My purpose in posting was to evaluate whether JMRI is suitable for what I am after for my own particular layouts, rather than to criticise the myriad volunteer contributors for not volunteering enough. I develop open source software myself, so I well know the inherent limitations on hobby developing.

Perhaps one day I might be inclined to attempt to write some of these features into JMRI (or at least write a script implementing these ideas and share it) - but I do not want to have to do this in order to get my planned model railways to work as I should like them.

The trolley discussion is very interesting, incidentally - it would be intriguing to see such a layout. It is interesting because it requires thinking about a totally different type of signalling system: not a system based on absolute/track circuit block, but based on driving by sight. This is used for road vehicles, of course, but also trams, all early railways, and many later industrial/light railways. Proper drive by sight would require some sort of proximity detector in each vehicle; but would end up being very useful for things such as coupling/uncoupling even on a normally signalled railway.

Thanks Bob, that's clarified it. I originally had the getThrottle in init but couldn't get it to re select the number so I moved it. In moving it, though, I also then did a few other things.

Problem solved by removing specific day for delivery in the schedule. ?Now it is on to fine tuning. ?Thanks for the help Dan.

Benny,

Use Layout Editor Tools to open the Entry/Exit table. Select Options >> Options from the table menu.

What color do you have set for “Initial color of path”? Based on your description it appears to be White.

If the setup process is interrupted for any reason, the track and extra colors are not set back. A subsequent save will update the panel xml file.

Paul, Just to throw in some other experiences, I have found the USB side of my interface to be more reliable. I was getting dropped connections from time to time with ethernet without any pattern to them. But I have a Mac, not a Windows machine on it. The USB has been flawless over at least several years now.

I'm actually in the (part-time) process of fitting driving cameras to trolley cabs that operate in real-time. Unfortunately, effort wise, for HO in my case,? that involves some time consuming micro metal work as well as the usual electronics. But I have to bypass most of the DCC features to get the signals back to the driver consoles.

The tough trick is then to get a non-human driven "smart" trolley to figure out it's own position based on its route history and what it can see/sense out front. Probably some collaboration with a central system using RPS and/or layout overview cameras is the way to go. But definitely not just traditional block detection. I'm thinking (backwards?) more along the lines of key positions having passive transmitters that identify their specific location code to the trolley, rather than dumb sensors that try to identify the presence of a trolley in on of very many, very short blocks . That way the length and quantity of "blocks" becomes a non-issue. And the trolley itself sends that info to the central system, as needed, rather than the location sending it.

And did I mention it all has to be cheap ;)

This kind of operation might require thinking outside the blocks.

I’ve had small parts in the work on two different non-blocked systems for locating model-railroad rolling stock.

*) One was RPS (), which even had some JMRI support (). It used ultrasound transmitters attached to DCC decoders for location. It worked, but it required hardware on engines and cabooses, and at the time was too expensive to be popular.

*) The other, more recent one used a couple of RPi’s with high-def video cameras looking at the layout to locate trains. Stable alignment was achieved through a couple of IR LEDs (visible to the cameras, not to people) buried on the layout. It basically worked, even separating trains on adjacent tracks in yards (which can be tricky because of shadows), although getting good coverage would have required more cameras because of poor layout sight-lines. Then it went sideways as my collaborators wanted to use IR LEDs to uniquely identify engines: More engine-by-engine hardware, etc.

Neither of those projects really worked out, but either method might work with some real attention. Or there might be even better ideas!
