I am developing a software package that is using the NI Field Point Ethernet device. It is a large hardware device and I have been asked to develop a simulator. In order to do this, I need to simulate the Field point devices. Does anyone know if the Ethernet protocol is simply the Optomux protocol wrapped in a UDP/IP message, or is it something else? Is the protocol documented somewhere? I have searched, but have not been able to find a document.
We use OPC to communicate with our hardware and this allows us to use an OPC simulator allowing us to change "input signals" in real time via a windows application running on the PC. The main application does not ned to be re-compiled or anything. It does not know or care where the values are coming from.
