I've been tasked with establishing some communication between a spectrometer (interfaced with by a laptop) and a process skid on a Profibus network to have data such as concentration/total mass/etc. appear on it's hmi. Ive had success in writing a program in C# that mapped this data to analog signals via an NI 6009 and the nidaqmx api to communicate with other skids but am at a loss when it comes to serial communication, how would this connection be established? Could I similarly map the data using some digital i/o device an/or Profibus interface module? I apologize, I'm completely new to this sort of thing, and any sort of Product/Resource recommendation would be much appreciated.
