The Threeway-Turnout defining inside the Switchboard

In the switchboard you can define also threeway-turnouts. These have 3 states (straight, left, right), which are controlled normally by two solenoids. The state "straight" requires both solenoids to be set to "straight", the state "right" requires the "left" solenoid to be set "straight" and the "right" solenoid to be set "right". For the state "left" the "right" solenoid must be set to "straight" and the "left" one to "left". This requires in analogue operation mode (if there is no additional logic used) 4 buttons (= two pairs of buttons) or in digital mode 4 ports of an accessory-decoder (= two accessory addresses).

Threeway-Turnout defining when using a 6021/6051, IB or compatible device:

If you are using a 6021/6051 or an Intellibox as digital central unit you must define a threeway-turnout inside the switchboard as an element with 2 digital commands per click. You can select the graphic out of the list of the predefined "three way turnout"-elements. Please obey to have always two digital commands defined for each state! The state "right" should be assigned to the lower one of the two digital addresses occupied by the threeway-turnout (which requires to have it connected this way to the accessory-decoder as well). The example below shows the correct settings for a threeway-turnout occupiying the addresses "5" and "6":

Threeway-Turnout defining when using an ECoS, CS or compatible device;
commanding via the direct syntax:

Using a fresh ECoS/CS from the vendor you will have no accessories defined inside the device's internal database. It is possible to command accessories with such a device "out-of-the-box" without having the defined if you are using the "direct" syntax (see page 21). In this case you must define the threeway-turnout in the same way as described in the example above, assigning 2 digital commands per click, because the digital central unit does not know what kind of accessory it is switching.

Threeway-Turnout defining when using an ECoS, CS or compatible device;
commanding via the regular syntax:

If there are turnouts already defined inside the ECoS/CS, then the "regular" syntax should be used to command accessories. The digital central unit is knowing what kind of accessory it is switching, and SDL will receive correct events relating to the states of the accessories. If you are using an accessory-address-translation table you can still use the already known accessories' real addresses. In case of the threeway-turnout the switchboard-element must be defined with only 1 digital command per click definiert werden. The third state must be defined as "2". The same has to be defined if you are using the device's database-IDs (>= 20000). The example below shows the correct settings for a threeway-turnout assigned to the addresses "5" und "6" when using a translation table (please obey: only addresse "5" has to be commanded):
