Hoi Marklin-users,
I have Märklin and use a CS2 and RocRail. Al my (old) locs are digitalised and running smoothly.
For two years a got a turntable (Märklin/Fleischmann 6652) with a DSD2010 digital decoder. I installed the tt on my layout and started to make it work with CS2 and RR..
On the CS2 (keyboard 225) its is working perfect, also on the layout screen.
With RocRail (RR) in manual mode / semi automode, everything is going well. When I change to automode and give the loc a schedule over the TT, the loc is waiting and waiting and…. I have to help RR bij moving the TT manual. So in automode the TT doesn’t automatically turn to the correct track.
My TT:
- 6 tracks (RR numbered 0,2,4,6,8, 10, DSD numbered 1,3,5,7,9, 11), CS2 keyboard 225,
- Each track a position detection zone,
- One detection zone on the bridge (RR-Enter) and one virtual detection point (RR-in)
- A virtual Bridge Block with the same name as the turntable (Draaischijf)
- In RR all necessary schedules and routes are made.
I have read almost all your tips/tricks on this forum and used a “Best Practices part 2” from” Digithal Bahn” (DSD2010) especially mend for the use off the DSD2010 decoder and RocRail, but I cannot solve the automode problem. Did I forget something, like actions or so?
I hope someone off the Märklin-users have some the answers for me.
Eef (Boegies)

Bonjour Eef
Welcome to our nice forum. Glad to have you on-board.
Here crazy Märklinist HO digital Rocrail control with a 7286 TT (the 6652 from Fleischmann redecorated & packaged by Märklin and a DSD2010 installed around 2013/2014.

My TT operation
- 18 access tracks
- 3 sensor zones on the bridge
- 4 signals, lighted shed + flashing light
- sound module
- because of too many access tracks, the DSD2010 is controlled by a separate RS232+USB adaptor+ specific "Zentrale" for the DSD2010. This is additional to the CS2/CS3 3Zentrale"
- because of the importance of (1) the orientation of the bridge (+ or - side) and (2) the minimization of rotation, I have TWO routes for each access track (to DS1+ and to DS1-with an output to lock / unlock the route to the + or minus side.
- the TT operates in manual mode, in click and drag mode, in schedule mode, in aquarium mode.
- at the time (2013) RR asked to create manually all routes to and from the TT.
- because of an older version of the DSD2010 reporting only 24 positions (newer report 48 positions I think) then I created a virtual switch 24+ indicating position 1-24 and 25-48

Here is the little I know:
- all block accessing the TT must be arranged so the MINUS side faces the TT (don't ask me why as I don't know)
- you have the option to include the bridge block of the DS declaration or to have it separate. I selected the separate option "Integrierte Block" is UNchecked.
- the "shortest rotation" to go to any position is managed by the DSD2010 but must be set correctly
- any incident in the dialog DSD2010-RR is not managed by RR and in this case YOU MUST RESTART RR.


What can prevent a loco to be sent to the TT?:
- the loco logical orientation must be toward the TT
- the block entry side (arrow) must point towards the TT
- the loco length must be smaller than the TT length So if RR still believes there are cars / wagons with the loco, access will be blocked. (It happened to me many times)
- the TT must be "unreserved" (like any other track piece (turnout, DSS, crossing)
- all sensors on the bridge must be free (check the virtual sensor)

I understand that only in manual mode you can use the TT (GO TO Track xx)

Just to be on the safe side here is what my track table looks like


Here is how the configuration is
Allgemein (General)


Schnittstelle (Decoder)


Gleise (Tracks)
sse the first attachment

all other DS1 tabs are left alone

The separate DS1 track
Allgemein


Fahrstrassen (Routes)


And here is the TT operation in video (schedule mode)


There are so much more to say that it is better to stop here and let you have more questions
*****************
I forgot to answer your question: No there are no actions required for the setup to work BUT BEWARE when adding virtual sensors , include correct setting at each RR restart (system action)

Cheers
Jean

Hi Eef

It looks like all is fine except the order to position the Turntable (TT) is not sent or not accepted
I understand that you can start a schedule through the TT, all is fine but the TT does not move. If, in parallel, you send an order to the TT then when it reaches the correct position, the schedule resumes and completes itself.

Can you drive your TT through Rocrail (right click on the TT, go to track x)?
If not then you must investigate why
If yes, then it is probable that the decoder refuses the order to move because it is reserved or the Block on the TT is not free
Good luck
Jean

Does your TT block shows your loco as its target?
If yes then the command has been sent to the DSD2010
To make sure, install a switch with the same address as the. destination track on your TT and see if it is activated
Cheers
Jean

Hi Eef
It shows the TT is not reserved
I would say the configuration of schedule to and from the TT do not include the proper TT command
You must work around that
Cheers
Jean

Hi Jean,
Thanks for the reaction. Your DS24+weiche is the direction choice?
I wil complete my routes with the direction choice.

Greetings,

Eef

Hi Jean,
The DSD2010 that I use is a 2021 version. I don't know off there are differences between your and mine version. I used the documentation supported by Sven Brandt for the installation off the decoders.
I look further for solutions ic what I have to change.

Eef

Hi Jean,
The download page is ' https://www.digital-bahn..._ds2010/dsd2010_doku.htm '. I have downloaded all documents already and used them for the installation off the decoders and the setup.
In my CS2 the 226 (green) the 180 turn option and 228 is the direction Clockwise or Contra Clockwise (CW and CCW) In RR is this the same, as far as I know.
Because Märklin only use 24 positions I choose for the dipswitches mode 3 (24 tracks and 1/2 half) In my DSD2010 is M08 the first/second half sensor and M09 t/m M32 are the tracks.
Untill now I used the Motorola and I will try DCC as protokol.

Greetings

Eef

Hi Jean, thanks for the explonation of the "Turn" command. I will hope to get the TT moving. Till now I stil have to move it manual.
I keep on looing for 'the' solution for automode.

Greetings

Eef

Hi Eef
What you describe makes perfect sense as the "go to track" command is also used by the routes to send orders.
It all focus on the track table where the track no (0 to 47) is converted into a a code to send to the decoder by Rocrail (1 to 48) but with a convertion.
There are TWO METHODS:
- the direct control by RS232 (that I use now) which sends the track number through the RS232 irrespective of the Märklin 7687 "old-style decoder"
- the direct EMULATION of the 7686 decoder where you can basically send orders from address 225 to control the TT.

The documentation of the 7687 is here
https://static.maerklin....876e4b34bc1574773383.pdf

The DSD2010 offers a convertion table to allow those 24 positions to be converted to the 24 track position really used (one uses rarely al 48 positions
Here is one assignment of really-used tracks into codes


One important thing to remember is a route sends order to switches also here so why not test with a swicht (turnout) programmed at the same address 229 for track 1 and 2, etc)

Cheers
Jean

Hi Eef

Driving my DSD2010 by MM2 works very fine for me and it is highly probable that using DCC will do EXACTLY the same (in your case working with Routes and not working with the GoTo command.

I think, in your case, because you drive the TT only using turnout commands, the way to fill the TRACK table is different to my case
You should check this
https://wiki.rocrail.net/doku.php?id=turntable-tracks-en
One possibility (I have not verified it)
- as Rocrail indicates the standard mode is 24 track (in absence of the RS232 link)
- in the interface TAB indicate the TT type (DSD2010). The address is implicit.
- in the track table left column you start with Track 0 until you last REAL track (e.g.: 6)
- in the track table Decoder Track column you start with Track 1 until (e.g.: 7)

In this case, you must have configured the DSD2010 (Track Definition tab indicating:
- where is track 1
- what tracks are used
- where is the pole change (used only for 2 rails but you must indicate where is the pole change)

Then I assume that RR will send Turnout commands in accordance with the TT DSD2010 track definition table
Cheers
Jean

Hi Eef
Sadly I don't know why the GoTo does not work. I started using the DSD2010 without an adapter (10 years ago) so it MUST work. Just a question of how. Maybe ask the Rocrail forum?
I have a question: since you should (must?) adjust the DSD2010 parameters using the RS232C Link ,(I think there is no other way. Is there?) Why not get yourself an RS232 / USB adaptor similar to this one?
https://www.ebay.de/itm/33431880...D%7Ctkp%3ABlBMUO7H2YXAZA
Using this, you can do all your testing and adjustments andc drive the TT much more precisely (all 48 tracks)
Cheers
Jean
