wayne_jackson Posted December 10, 2014 Share Posted December 10, 2014 I have read the manual twice, and I cannot find anything beyond the basics, but is it possible to query a points' decoder or a signals' decoder to verify its status?Just because it is flagged as being set, I would like to check that it is before allowing the next step to proceed.

St1ngr4y Posted December 10, 2014 Share Posted December 10, 2014 Hi Wayne,I'm not quite sure what you mean by "flagged as being set" or "the next step". However, generally speaking there is no feedback from an accessory decoder to either the controller or Railmaster.Ray Link to comment Share on other sites More sharing options...
RDS Posted December 10, 2014 Share Posted December 10, 2014 Hi RayI don't have any motorised points (yet) or signals but I believe what Wayne means in terms of flagged would be similar to when RailMaster is displaying the status of Headlights on a Loco, in that the relevant 'Function' button becomes highlighted, sometimes referred to as flagged. The next step I believe means for example setting a Loco off, assuming it will take a particular direction at a points junction.I agree that there is currently no feedback but this would be useful because many a time, my RailMaster screen shows that the Headlights of a Loco are on, when clearly they are not.

However, accessory decoders for points and signals were specifically mentioned in the question, and as far as I know these don't send feedback info.Ray Link to comment Share on other sites More sharing options...
96RAF Posted December 10, 2014 Share Posted December 10, 2014 The problem with rm is a toggled function indication can get out of step betwixt elite, rm small loco throttle and expanded throttle.points should display their selected state on the track plan via the blue line indicating way set. Doesn't mean that is its actual state. That can be confirmed by LEDs set by points actuated switches. Link to comment Share on other sites More sharing options...
Fishmanoz Posted December 10, 2014 Share Posted December 10, 2014 To points again as per the question, there may be no feedback but the RM screen shows you which way it has set the point via the highlighted red or green button and the blue/grey route indicator on it.

wayne_jackson Posted December 11, 2014 Author Share Posted December 11, 2014 This might actually be a fucntion of DCC itself, rather than RM. I have noticed quite a few times that just because I have actioned something in RM, it does not mean it will be actioned on the layout.A few times now I have had to remind locos to stop, or have had to send a command more than twice to get it to action properly.When working with XBEEs for RC trains, because they are trancievers, I can send checksums based on the instructions. If the checksums do not match, then I just resend the message or send a EMERHALT to the network.If I had more room inside the shells, I could convert these all to XBEE or WiFi.

HornbyRailMasterSupport Posted December 11, 2014 Share Posted December 11, 2014 Accessory decoders do not feed back their status to DCC controllers or software, therefore RailMaster must assumed that when a point or signal is fired that is has indeed been fired and shows this on the plan. To be more sure, RailMaster sends a double pulse in case a point is sticky. Link to comment Share on other sites More sharing options...

Hi Ray, Yes I realised that but I was just trying to give an example of 'flagging' Link to comment Share on other sites More sharing options...
wayne_jackson Posted December 11, 2014 Author Share Posted December 11, 2014 Thanks HRMS. That is the line of thinking I was beginning to have. Link to comment Share on other sites More sharing options...
