Can anyone recommend a HMI (company/model) for use in outdoor field work? We require a handheld HMI which has good visibility in sunlight (possible direct) as being light weight.
Is there a technical term for handheld HMI's which simply plug into a terminal (i think just straight rj45 connection), which can be transported to another site using the same unit - ie the program is loaded (somewhere) and all the operator does is plug the unit into the terminal? - it would make it much easier to research.
We currently use mounted UniOp and Hitech HMI's. Ive done some research on Exor/UniOps ePalm unit, which is a handheld, however it is not suitable to take to other controllers.
I also dont want to be too picky, it doesnt need to be flash (such as color or tourchscreen), and it shouldnt have to be programmed in an object oriented programming language (java is evil)
