Thank for your answers.
But in this case I have already talked to our Rockwell support here in Germany and the only answer is, that Windows XP embedded is not supported in combination with RSView.
So I really don´t know if I should go this way. The only thing the customer support representative told me is, that he knows about other customers who were using Windows XP embedded with RSView.
I am thinking about using XP embedded because I want no Harddisk in the HMI Panel PC instead of this I want a compact flash card.
While using a compact flash card, the normal Windows XP would damage the flash card in short of the time because it stores different files again and again and those memory cards are not suited to do so.
