Hi MichaelThanks for the reply. Yes I know that from the software side there are not many differences (backwards compatibility and all). I guess that my question was not so clear.
The biggest problem we have is in finding the hardware - simple DAQ boards an so on. There are PXIe boards, but to find a cPCIe multipurpose DAQ board turned out to be quite the challenge. Even for the CPU there are not so many manufacturers (MEN elektronics have cPCIe , than mostly PXIe cpu boards by NI, Adlink, geotest). I know that PXIe can be used as a cPCIe (some additional synchronization features of PXI are lost), but when looking for pure cPCIe the resources seem to be quite limited. So I thought I'd post here, If anyone else has had experience with setting up a cPCIe system (from hardware point of view).

Hello Urša,When you speak with software developers you may not hear PCIe explicitly mentioned often. For software there is (intentionally) little difference between PCI and PCIe.In our server systems we use PMC modules with a PMC-PCIe carrier card. This presents a transparent bridge. No software changes were required to accommodate this.Michael Davidsaver NSLSII Controls Group Brookhaven National Lab On 5/14/2012 5:09 AM, Urša Rojec wrote:Dear all,I am looking for comments and suggestions on cPCIe. Do you use any cPCIe modules as part of your contols? Could you tell me the module name, manufacturer?I have been looking at tech talk and cPCI express is not mentioned. Is nobody using it?Any help would be appreciated. U
