Hi,
I have a need to get some add on instructions created which I can use as generic instructions between programs. I wish to create a simple scale so I can basically take in any type of analogue signal and convert that signal to a real figure, I would like to create a scale for temperature control, one for pressure and one for level within this I would also like to be able to have set points which relate to the scaled figure.....Can anyone help me to create these in a simple step by step format and does anyone know of a company who create custom add ons to order as I have several big projects on the go at the moment.

Thanks in advance

Dan
