JMRI and the decoder Panels
Hi,
A very long time ago (6yr or so) I was able to use JMRI and the panels to read the MACROs of? the Clubs layout to allow me to change if needed, one at a time, not having to REDO the MACRO, best thing since sliced bread.
?
WAY back then, it was just a matter of plugging in the USB Cable to the CONTROL PANEL on the layout, the other end to the computer, starting JMRI and get the PANELs and the macros to show SOMEHOW :)
?
For one reason of another the above method was FORGOTTEN about, sad to say wanting to do something again, the MEMORY is not so good.
?
More later perhaps
Graeme

Re: How do I import openpyxl?
¿ªÔÆÌåÓýNick, ? Why not use the built in Operations to hold the car inventory? That would be a onetime export to CSV and import to JMRI. Then your script could query that database. ? -Ken Cameron, Member JMRI Dev Team

Re: I think I have JMRI 5 and JAVA 11 loaded on my Win 11 computer
Hi Steve,
THANKS for your reply,
My computer details are showing me that the USB cable is connection to my COM 3, I go through all the DECODER PANEL settings an wait for a few section, only to have shown in RED.
I will have to wait till I get back to the CLUB and some ELECTRONIC EXPERTS there may be able to help me
?
Thanks Graeme |

Re: Roster Missing
Dan, It appears that when DecoderPro stops unexpectedly under certain conditions, the roster index file (roster.xml) is lost. ?The roster entries in the "roster directory" are not affected. The unknown at this point is whether this is a general JMRI issue or an OS specific issue.

Re: How do I import openpyxl?
My car spreadsheet (600+ records) has the following fields: carID, type sub-type, road, number, length, color, built, manufacturer, ?weight, wheels, resistance wheel (Y/N), couplers, coupler screw (Y/N), weathered )(Y/N), date last checked, load (if any), comment; and new fields I added for the barcode reader code: destination pointer, destination 1, destination 2, ....destination n (typically 4 to 8 destinations). I primarily use this spreadsheet to keep track of my cars and what I need to do to them.
-
My layout centers on the Enola freight yard in Harrisburg, Pa. Trains arrive from various cities (staging), cars pass over one of two humps, eastbound or westbound, and are routed to new trains which depart to destination cities (staging).
-
I read the carID as the car passes over one of the two humps with a bar code reader. The program gets the car length and next destination from the car spreadsheet. I find the next destination by incrementing the pointer each time the car returns to the hump for classification. That way the car will cycle between 4 to 8 destinations, eastbound and westbound.
-
In a second spreadsheet, given the destination, the program finds the next train (of about 20 scheduled trains) bound for the destination and its assigned track. The assigned track is updated in the trains spreadsheet by the departure yard master during the operating session. The available track length is decremented by the car length and then the new available track length is written back to the spreadsheet. When no room on the track is left, the program routes the car to an overflow track.?
-
In jmri, when the track is entered the program adds the commands for the turnouts involved to a turnout.list. Since more than one car is rolling down the hump at a time, turnouts can't be thrown until previous cars have passed over it. When a car passes over a turnout, photocells activate a sensor and Logix runs a script which clears the top command in the turnout.list and throws the turnout to the next position in the list.
-
I haven't had a chance to study the csv examples yet. But, if I run the program outside of jmri to find the track number, I really only need to pass that track number into jmri which may not be that hard using a csv file as an intermediary. Then I can run the rest of the script in jmri to enter the new turnout commands into turnout.list and eventually throw the turnouts and control panel lights.?
-
Hope this wasn't to much information. If you are interested, I've uploaded the program into files as Nick Brownsberger's hump control program.

Re: LogixNG POM
#logixng
¿ªÔÆÌåÓýVinny, It seems that you want to have a memory with the current volume. And then a ConditionalNG that copies the value of the memory to a local variable. You then does the addition/subtraction and store the new value in the memory. And then you do the POM. Note that memories usually uses strings, not numbers, so you
might need to convert the string to a number. Daniel

Thanks Ash.

Is the use of the <JI> command between JMRI and DCC-EX (running on an uno) therefore dependant on a JMRI update before it can work??
There was a setup menu of sorts under the current monitor submenu, but I didn¡¯t get a ¡®none available¡¯ message, just a little blank square pop up, which I assume was supposed to be that message. Makes sense, since I¡¯m running DCC-EX on an Uno, as you say.?
I¡¯ll take a look at Discord (never used it before) and see if I can pick the brains of the DCC-EX guys. |

Re: LogixNG POM
#logixng
I added Vinny to the symbol table.
now the error is gone but it's not doing what I expect.
I am writing to cv63 which is master volume. I have an ng for up and one for down. I want to increase or decrease cv63 by the # in IM1. |

Re: How do I import openpyxl?
Would it help to ditch the excel file and store the car information in the roster instead? You'd need to have 600 (necessarily long) dummy addresses to use. Having the cars? in a separate roster group would keep them from getting tangled with your actual locos. If your car data can be massaged to fit in an entry in the roster I think you'd be good to go, since you'd no longer need an excel interface at all.

Re: How do I import openpyxl?
Dave,
?
To answer your question, I have an Excel spreadsheet listing about 600 cars with various information about them like type, road, number, etc. I'm using a barcode reader to identify a car ID as it rolls over a hump and send it to a Jython program. The program gets some car related information out of the spreadsheet such as car length and destination. Then it looks up the train and classification track assigned for that destination and throws turnouts to send the car to the right track.
?
Right now, using openpyxl, the program works outside of jmri to get the track I need, but it can't throw turnouts without being inside jmri.
?
It doesn't sound like openpyxl is compatible with jmri and Apache POI is way over my head.
?
I'm looking at using csv files, but manipulating a 600 record csv file sounds daunting. Or, I could instantiate a class of 600 cars in the Jython program which I was trying to avoid. I'm also rethinking my strategy as well.
?
Thanks to all,
Nick
