Hi,
I want to save a value in a vector. I try with an array but I have a lot of problems.
Thank allhttps://forum.trihedral.com/index.php?u=/new_topic

Sorry, but could you please add a bit more detail to that question? What do you mean by a vector? Is this for I/O, for local storage, or for graphics?

Assuming you are actually looking to work with vectors as in quantities with scale and direction; I'd suggest making a custom tag type with a child tag for each axis of your coordinate system.

For example, you could make a tag type such as the following:
VectorName
|-->i-component
|-->j-component
|-->k-component
|-->Magnitude

This way, you can easily create a new vector tag such as vector1 which will automatically get the child tags and even any other calculations you want.

I should note that in the VTScada expressions, ^ is a bitwise or operator, not the 'to the power of' operand. If you want to get the magnitude of a vector, you'll need to use the following expression: SQRT(Pow([i-component],2)+Pow([j-component],2)+Pow([k-component],2))

Hopefully, this can get you started. That said, better understanding what you are looking to accomplish would be helpful as we may be able to provide more specific advise.
