Peco 3 way points

 

I'm new to JMRI, and have been charged with re-wiring a layout and making it work.?I've managed to draw the layout in PanelPro and assign turnout numbers, and get crossovers working, but that is as far as I've got.
?
There are about 6 peco 3 way turnouts, I've drawn each of them as 2 separate sequential turnouts, but they cannot work like that. They need special treatment, which is currently beyond me.
?
The 2 pairs of point blades are very close together such that the blades need to be set to the mid straight route before being set left or right. Some are also parts of crossovers just to make things more interesting.
?
What is the simplest way to do this ?

The two points are controlled by two control devices.
You essentially have two turnouts.
Control them like two turnouts.
?
You could create a selector using Logix or LogixNG and select with panel buttons.
I'd be inclined to create 3 routes in JMRI and operate them with route selector buttons on a panel.
Depending upon your hardware, you might be able to set this up in your controller hardware.
I have hardware that will let me make a selector out of multiple turnouts (I use for yard ladder).

I just looked at?

Looks to me like two regular points that happen to overlap. At least, that¡¯s how I treat my Roco 3-ways

One controls the route from the toe to the first exit OR to either of the second/third. Then the other point controls which of the two it is

I think the problem is that two turnouts have four possible states, but only three of them are mechancially safe. Referring to the image in the link above, the 3-way must not be set to ¡°left-most points up, right-most points down¡± because the point motors will be fighting each other.

Hello Mike. I set up? a logix for it. I also added 2 virtual turnouts which are used on the layout editor. While straight ahead is straightforward, it is the sides that cause problems. Before you can use for example the lH turnout, you have to make sure that the RH is straight, and vice versa.
So on a 3 way, I have where S is the connection, X is the turnout number, t is the turnout, and V is the virtual
SXt (V)? ? ? Left hand virtual turnout
SXt,? ? ? ? ? ?Left hand real turnout
SX+1t, (V) Right hand virtual turnout
SX+1t? ? ? ?Right hand real tournout
?
The logic would go something like
if SXt (V) is thrown
? then?
? ? ?close SX+1t
? ? ?delay throw SXt
? ? ?delay close SX+1t (V)
endif
?
change the order for the other side
if SX+1t (V) is thrown
? then?
? ? ?close SXt
? ? ?delay throw SX+1t
? ? ?delay close SXt (V)
endif
?
?
This has worked well on my last layout and will be used on my next one as well.
I hope you understand it.

Absolutely Bob
JMRI routes controlling those actuators via panel selector buttons would solve the possible "conflict".

.... and 3 virtual turnouts acting on the JMRI routes would work as well as panel buttons.
