Hi guys,
Just joined, had a bit of a browse and most people seem to know more than myself regarding PLC's which is a good start.
Quick bit about me. Im a 21 yo student studying at Murdoch University in Perth, WA. Im studying what amounts to be Electrical engineering, specifically Im doing a double major in Industrial computing systems, and I&C.
to the problem at hand:
Im trying to put together a proposal to install a experiment panel for a I&C lab, using a NI master server, and mostly 4-20mA loop powered devices. However Im told I have to implement a PA profibus Differential pressure device as well as the standard 4-20.
The problem is, none of the staff have any idea about profibus and have already purchased the EH transmitter.
From what ive gathered, I have to install a PLC (siemens 3xx) and create a profibus network for the instrument, before outputting the value through an analog channel ot the server's DAQ card.
Im interested in hearing some advice as to the Hardware Ill be needing to request to make this happen. So, far I have a PB transmitter, PB capable PLC and a DP module (CP-342-5) that connects to the PLC.
I think I need ; 1) DP/PA coupler;
Any input will be appreciated.
Thanks
Dan.

2)Terminating resistor
on top of the equipment I already have available. Im told siemens also supplied the PB fieldcare software.
Any input will be appreciated.
Thanks
