I'm new to Profibus so I'm not sure what I need to connect a Profibus PA Differential Pressure meter (http://www.yokogawa.com/fld/PRESSURE/EJA/fld-eja110a-01en.htm) or possibly meters to my existing PC104 embedded computer.
My embedded machine has a RS232, RS485, 4 USB, and an ethernet connection and its' running Windows XPe with Labview 2011. From the searches I've done I noticed that I may need an interface board such as DF PROFI II PCI/PCIe/CPCI/PC104+ http://www.comsoft.de/html/icpe/products/profibus/interfaces/dfprofi2.htm and maybe some kind of coupler to switch from PA/DP. If all that sounds correct, is the DF PROFI II PCI/PCIe/CPCI/PC104+ a good choice and what would be a good coupler to use? Could I somehow communicate with the Differential Pressure meter using the RS485 and skip the interface card altogether? Thanks
