Toroidal transformer

i have a toroidal transformer the first pic is the diagram on th transformer and the second is what i think i soulhd do to get P=230v S=50v-0v-50v is that correct?

Yes.

The dots are important. Those taps have a direction relative to the other taps. If you screw it up on the output side you get nothing, but if you screw it up on the input side the inductances cancel each other out and it acts as a short circuit. Test with a fuse.
