#516 Inappropriate EStop Emitted by webThrottle.html

[Anonymous]

Most times when using webThrottle.html and clicking the throttle down to 0, instead of sending packet to set throttle to 0, it sends an estop command.

This does not allow expected operation of the deceleration feature of the decoder.

IMO, if I want an estop, I'll use the estop button, the throttle should be
JUST the throttle.

It does work as I expect it to work maybe 2 to 5 % of the time. I'll be happy to assist in the investigation as I can, ralphATkreipleDOTnet

It would help a lot to know which DCC system and which decoder you're using.

A note to anybody following up on this: Due to favoritism toward one manufacturer, the NMRA made some spectacularly bad choices in defining this aspect of DCC. Sending a value of '0' in the DCC packet is stop; sending '1' is e-stop; sending '2' is the slowest non-stopped speed. But not all decoders properly handle that, and some DCC systems will decrement through '1' on their way from '2' to '0'.

The JSON throttles send a floating point number from 1 to 0 for speed and -1 for eStop to a jmri.Throttle instance. If the decoders mattered then this issue would be exhibited from JMRI throttle windows and WiThrottles. Should we expect to see this from certain known decoder types?

The -1, 0->1 is converted first (in JMRI) into commands to the DCC system, then (in the DCC system) to a DCC signal, and then (in the decoder) to motor control. So lots of places where it can go wrong.

I've heard multiple times of different DCC system & decoder combinations that have a problem with this, but I've never seen it myself, so don't have any specific information. Hence the desire for a specific DCC-system & decoder combination that does it.

The function is as expected. No EStop

[NMTrain]

Also, using the JMRI "regular" (don't know the technical name for it) throttle, the EStop issue never occurs, behavior is expected.

Another curious observation, if I leave the "reg" throttle up, the winTrottle behaves well, as soon as I kill the "reg" throttle, inappropriate EStops happen.

[Bob Jacobsen]

Thanks! The trace makes that clear. Somehow, the computation inside JMRI is resulting in sending a "1", which is the ESTOP value. Particularly interesting that it doesn't come from the on-a-JMRI-screen throttle, just through a webThrottle. Maybe that's telling us something.

It's also odd that the sequence is 14-ESTOP-14. It's not like it was calculating something close to zero or 1 and got confused.

[NMTrain]

I did a little investigation:

This seems to prevent the problem:

/*************

Snippet of 'webThrottle.html'
* *************/

//----------------------------------------- Function for speed control
var functionForSpeedCtrl = function() {
var speed = $('.speed');
var speedValue = Number(speed.attr('speed'));
if (speedValue < 0) speedValue = 0;
var speedLimitsHeight = $('#speedLimits').height();
var speedBarValue = $('#speedBar').offset().top;
var increment = (speedBarValue - $movementCtrl) / speedLimitsHeight;
var maxIncrement = speedLimitsHeight * $speedStep;
speedValue+= (increment > $speedStep ? $speedStep : (increment < $speedStep * -1 ? $speedStep * -1 : increment));
if (speedValue < 0) speedValue = 0;
if (speedValue > 1) speedValue = 1;
speed.attr('speed', speedValue);
showSpeed();
var speedValueFormated = '' + speedValue;

// replace, when inappropriate estop occurs, speedValue almost always has .003174604475458194
// if (speedValue == 0) speedValueFormated = $jmri.STOP;
// if (speedValue == 1) speedValueFormated = $jmri.FULL_SPEED;
// with
if (speedValue <= 0.005) speedValueFormated = $jmri.STOP;
if (speedValue >= 1) speedValueFormated = $jmri.FULL_SPEED;
// I also tested for > than 1, not that I ever saw it, but it should be safe

$jmri.setJMRI('throttle', $locoAddress, {"speed":speedValueFormated});

};

[Randall Wood]

I think this has been fixed in the latest nightly builds.

Can you please test with the most recent nightly JMRI build?

You will need to test without the modified webThrottle.html file.

[NMTrain]

I have just downloaded package #2094, I will setup another computer, and give is a try and report.

[NMTrain]

I have restored the original code, recreated the problem.

I then installed package 2094 and with three loco's and 15 minutes of trying, the problem did not occur.

Looks Good!

[Randall Wood]

Thank you for testing this. Am closing it.

For reference, the issue was that certain system-specific implementations of the throttle speed setting logic would set throttle speed values close to 0 to the eStop setting.
