using PXI-8840 to communicate with EtherCat slave

Hi guys,

i'm always using a PXI Chassis (PXIe-1065) with a controller PXI-8840 for our projects. Now i'd like to use this controller PXI-8840 to communicate with our own EtherCat slave product. Is there any way to make this controller as a ethercat master, or is there any PXI-cards to make the communicate work? Thx a lot.
