Hello

I want to create a 3 way state switch (off,auto,manual) with one input

The status (off,auto,manual) sould be displayed in a text message

I hit a wall when i tryed to convert a counter value into an output.

Can anyone help me with this ?

Kind regards

Hello koekjesdoos,

No matter how you do it, a 3-way switch always requires two inputs ! Just to detect the precise "off" switch position.

By the way, a program is always more helpful than just a picture.

Here you have two options to choose from.

It would be interesting to know which version you prefer.

Hello Qurin,

Your suggestions are well-intentioned, but if a wire breaks at the switch during operation, you won't be able to shut it down.

I've also thought of something that takes wire-break safety into account and shuts down the system in the event of an interruption.

But I personally consider this a very poor solution, too, since the operator may not be immediately aware of the switching mode, and the system will start up with a delay after the time set in B005 has elapsed. This could lead to misinterpretations or even accidents.

Hello, Ella_68 and koekjedoos

It is true that with just one button, you cannot create a "safe hand automatic switch"! 

I agree with Ella_68 and advise against attempting such a solution due to the lack of safety!

A solution with 2 inputs and a three-position switch, on the other hand, is harmless and safe.
