Thanks Paul. That is very useful.

It looks like you’ve confused two different structures. The AbstractAutomaton class (see the “class” line below) uses methods called “init” and “handle”. The Siglet class uses the methods called defineIO and setOutput. So try changing the class line to

class Three_aspect(jmri.jmrit.automat.Siglet) :

I got the NCE lightits to work by addressing them 1 thru 3 and setting them up in the signalhead table and testing them on the table. I then use the script:

Changing the color and it worked.

I then ran the code in the below and it does not work I am looking for suggestion as to what I am doing wrong. I am wondering if I would be better off defining the turnouts in the turnout table like I did for the signalheads.

If so I just need to monitor the sensors and need to command to do it. Any help is appreciated.
Thanks Paul

Try this link. It is a power point presentation on using OperationsPro

Thanks Gerald. I browsed through this and seems something I can learn from.
Are you aware of something similar for Operations?

Two months ago a? gave a clinic on Decoder Pro. This was a "Hands On" Clinic where those attending were in "paired" with a friend for the clinic. The clinic took 4 hours - 2 in the morning then a break for 1 hour for refreshments then another 2 hours. Each pair had a system set up on the table so they could try things out as the clinic progressed.

For this clinic I put together some notes - with plenty of explanations. Those who attend (20 of them) had either a Sprog or an NCE system, with a laptop - all Windows. As I knew everyone in the clinic, their layouts, and roughly the skills the notes were 'tailored' to suit.

I have put the notes (20 pages) on the web for anyone to download and read. The notes were written in Australian but should translate easy enough to American or English.

May or may not be of help.

I cannot answer all your questions but I was in same boat when I started learning JMRI earlier this year with no one locally to help me. I could read the guide but it left me with a million questions. I eventually found numerous tutorials on line that provided "how to" example. That got me over the hump in my learning curve. Do a google search for JMRI tutorials and several will show up. My biggest problem with almost all I found was that they were built using older versions of JMRI thus the screens did not match very well with the latest versions. However, they still were very valuable.
I have a Digitrax layout thus I use Loconet. When not connected to my layout, I use the "Loconet Simulator" to play with my JMRI files.

Is there a way to attach a screenshot to a post?
I was trying to build a train and it gave this error "Train requires 1 locos, could not pick up at departure(Cassette) or set out at (Cassette)

Thanks for that. Looks like our webmaster removed the page completely since registrations closed last week, but didn't provide an explanatory page or redirect.

He may have told members at club meeting yesterday but I was in hospital undergoing surgery.

I'll remove the link from my signature and chew his ear...

I don't think I'd downloaded the Program either... But I'll be there answering questions all weekend.

Dan,
Either the values field or the comments field would work for me. I am looking for a field where I can put in multiple lines rather than a single string of text. I would hope that it would show up as multiple lines when I use the export feature even if they remained as a single field.
Paul D

Clay,

There was an issue with that older version that would 'on some specific
systems' take a very long time for the tables to open. It was related to an
issue with the audio libraries. But to open the tables, that would trigger
it.

Just update and you should be fine.

Paul,

The easiest way to learn how to use scripts in JMRI is to start with the discussion found at and work with the simplest examples provided with the distribution downloaded and installed on your computer.

Often an example script will provide a simple starting point for your problem. Provide lots of print statements or learn how to use the

import org.apache.log4j

to put log statements in the JMRI System Console. Make small changes and when some incremental progress is made, save the file with a new name. Do that early and often.

A significant rule when using AbstractAutomation is that you must supply at least the two functions named init() and handle() to at least get some kind of output. After cleaning up some of the indents of your text and inserting a few obviously wild guesses the following code produces some error messages, most noticeably a missing function definition.

Without a better understanding of your system and what problem you are really trying to solve, all that I can do from here is to throw the ball back into your court.

Is there a starter tutorial that I can follow step by step to understand JMRI.
Currently, I do not have a command controller that I connect to. Hence, I would like to use a simulator, if possible.
Also, I understand that SoundPro can be used to play sounds even if the locomotive does not support sound.
Is it possible to test this also in offline mode?

You can copy the whole profile directory from one computer to another. Then
update the connections to simulator.

When I open Panel Pro, go to tools, then tables, and try to select either turnouts or sensors so that I can add them, nothing opens up. I haven't done this in a while and wonder if something has changed since I last did this. Running version 4.10 on a Windows 10 PC. Thanks in advance.
