Locked Re: How to change the systemName of a turnout or block in a script? #scripting

 

I've done the sequence like Cliff described while a layout is being constructed.
We started with a all Internal layout design as part of the planning process for
the layout. Then as we built and installed electronics, I would move the user
names to real hardware. This kept is as a bunch of smaller batches of changes.
Then we used the panel to test the new hardware on the layout. Repeat as needed.

That's very interesting. Okay, so if Nano's are 5v then we would still need the Level Shifters. Not s problem, just trying to work out in my head what we might need.

Forgive my ignorance, but would we need a MAX485? Are you thinking of connecting multipe Arduino/reader boards together on a RS485 bus and having one connection to a computer? That would certainly be interesting.?

Just to make sure the Uno and Reader were working, I removed the shield and uploaded the plain Serial sketch. The tags were read okay, so not these bits of hardware. So a bit baffled, I decided to upload the original Ethernet sketch that I call v1. It still didn't read any tags, but with JMRI it held the connection!

Again, I couldn't see the shield on my router. I would have expected to see 'Wiznet' and the IP address. Perhaps you don't get Hostnames with these shields? Just in case it is the shield, I have ordered another one. You know my luck with faulty equipment! Lol!

So, I tend to think the shied is actually okay. But something is wrong with both sketches inasmuch they do not read the tags. Ethernet sketch v1 does hold a JMRI connection, but seeing as the sketch isn't reading any tags anyway, I'm not surprised it don't see anything in the Reporter Table. The recent Serial/Ethernet sketch also does not read any tags, but has an error connecting to JMRI as well!

So, any ideas?
Steve,

I'm sorry to hear that the sketch is not working as expected. Let's try to debug the issue step by step.
?
First, let's make sure that the Ethernet shield is not interfering with the RFID reader. Disconnect the RFID reader and upload the following sketch to check if the Ethernet shield is working properly.

#include <Ethernet.h>
?
byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
IPAddress ip(192, 168, 1, 177);
EthernetServer server(8888);
?
void setup() {
? Serial.begin(9600);
? Ethernet.begin(mac, ip);
? server.begin();
? Serial.println("Ethernet server started.");
}
?
void loop() {
? EthernetClient client = server.available();
? if (client) {
? ? while (client.connected()) {
? ? ? if (client.available()) {
? ? ? ? char c = client.read();
? ? ? ? Serial.write(c);
? ? ? ? client.write(c);
? ? ? }
? ? }
? ? client.stop();
? ? Serial.println("Client disconnected");
? }
}

If the Ethernet shield is working correctly, you should see "Ethernet server started." on the Serial Monitor. You can also try connecting to the IP address and port using a tool like PuTTY or netcat to test the connection.
?
If the Ethernet shield is working correctly, let's try to isolate the issue with the RFID reader. Upload the following sketch to test if the RFID reader works when the Ethernet shield is connected.

#include <SPI.h>
#include <MFRC522.h>
?
const uint8_t SS_PIN = 5;
const uint8_t RST_PIN = 4;
?
MFRC522 rfid(SS_PIN, RST_PIN);
?
void setup() {
? Serial.begin(9600);
? SPI.begin();
? rfid.PCD_Init();
}
?
void loop() {
? if (rfid.PICC_IsNewCardPresent() && rfid.PICC_ReadCardSerial()) {
? ? Serial.print("Tag UID: ");
? ? for (uint8_t i = 0; i < rfid.uid.size; i++) {
? ? ? Serial.print(rfid.uid.uidByte[i] < 0x10 ? "0" : "");
? ? ? Serial.print(rfid.uid.uidByte[i], HEX);
? ? }
? ? Serial.println();
? ? rfid.PICC_HaltA();
? ? rfid.PCD_StopCrypto1();
? }
}

Make sure to disconnect the Ethernet shield from the Arduino Uno before uploading the sketch. After uploading the sketch, connect the Ethernet shield and test if the RFID reader works.
?
If both the Ethernet shield and the RFID reader are working correctly in isolation, there might be an issue with the combined sketch. In that case, we'll need to review the sketch further and investigate possible conflicts between the Ethernet and RFID libraries.
Please try the steps above and let me know the results. We can then proceed with the appropriate debugging steps based on your findings.

Okay, so I tried the latest sketch modified for four readers. Well it uploaded okay and the Serial Monitor started with a train of '.' then 'Connected to SSID'? and on a new line 'IP Address: IP'. My router sees the WeMos and correctly reports the IP address.??

However, it does not read a tag. When I use JMRI, the main panel shows the flashing 'Rfid: Using SSID:Port' in black to 'Rfid: Error using SSID:Port' in red at 0.5Hz.?

So, it would seem to me that the sketch is hanging somewhere after the line 'Serial.println(WiFi.localIP());', as that seemingly is as far as it gets. Although I'm wondering if it is actually getting as far as the line 'WiFiClient client = server.available();' ?it certainly doesn't get further than that as no tag is read.?

The flashing connection message in JMRI would lead me to believe that the WeMos connects momentarily, then disconnects before trying again. I wouldn't know if it is the WeMos dropping the connection or JMRI.

The steps described in the previous note will work for Blocks too, except that the added Blocks will not be required to have DCC hardware addresses, but could mimic that format if desired.??

Steve,

Blocks don't have connection based system names, they are internal. ?However, blocks do need occupancy sensors. ?A recent PR added the "AnyRailBuildBlockSensorList.py" script.

For the turnouts, you need to figure out how to map the AnyRail generate internal turnout to your real turnout. ?Once the mapping has been defined it should be possible to manipulate the JMRI tables. ?Parsing the xml file can be problematic since the turnouts are grouped by connection type.

Locked Re: How to change the systemName of a turnout or block in a script? #scripting

 

Steve,

What is described here works well for small layouts, but can be painful for a lot of Turnouts or Sensors and even more so for Blocks, since Blocks do not have any hardware or DCC addresses.? The same steps will probably work with some modification for LCC hardware addresses, but there are details that I cannot verify for that issue.

Only the steps for Sensors are given here, since the simple replacement of the word Turnouts will suffice:
  1. From within either the Tools >> Tables >> Sensors window click on the "Add..." Button.
  2. From the dialog, select your "System Connection:" hardware choice.
  3. Enter at least one hardware address but leave the User Name field empty and click the "Create" button.
    1. My preference is to do only a few at a time, but one can enter as many as is easy to keep track of
  4. Then pick an existing Internal Sensor from the Sensor table window and right-click the "Edit" button.
  5. Select the "Move User Name" option from the pop-up menu.
  6. The list of created Sensors with no userName assigned will appear for the move-to choice.
  7. Repeat steps 1 through 6.
Nobody said it would be fun, but it works.? At least it works if the Panel file is saved early and often.

QSI work fine on small layouts.
IF you have several and no issues, they are fine.
On large club layouts, we had lots of issues. (Including trouble reading on digitraxx programming track, and decoder scrambled when another user shorted.
Your experience may vary.

Blair, Nick

I think it highly unlikely that this is a power problem. The Uno with just one MFRC522? connected doesn't read the tags with either Ethernet sketch, with or without the shield. The same Uno and reader are absolutely fine with the Serial sketch. To me, it points to something in the sketch.

My current workflow is that I create orders and assign cars in an Access program separate of JMRI, then I assign the final destinations to the assigned cars in JMRI, which works great.?

The only method I have discovered to do that is to lower the move count of the assigned cars, which works pretty well.? I don't want to keep changing move counts of cars though because I then lose track of how many times a car has actually moved.? It's not a big deal, but not ideal.

Is there any way to prioritize a car when building a train other than lowering the move count?

Thanks.

Tom,?

As you may have discovered, you can assign priority to any custom load you have set up.? The program will consider any car with medium or high priority before it tries to moves a car with a low priority load.? The low load priority is the default setting and must be changed to execute this ranking of car loads.? Also, be aware that this applies to the load and NOT the car-type, so it can be used for different scenarios like keeping the priority of an empty reefer at medium rather than low, as may be the case for other non-time critical cars (think coal hoppers).

Happy to help, hope it helps,

All this is found under the Trains Window--->Tools--->Build Report Options...
