What is the fastest way to send 8 AI channels (AI-100) (8bit number signal, 0 or 5V) from an FP 2010 to 8 digital outputs (DO-400) connected to an FP-2000?

I need to send the information through an ethernet network from the AI-100 connected to a FP-2010 to a DO-400 connected to a FP-2000.

The easiest way is to use the DataSocket VI's to link from one FP-20XX module to the other. Since you want to transfer numbers that are the results of calculations, you would use the Publish Data.vi on the FP-2010 to publish the 8 bit number signal. On the FP-2000 you would use the DataSocket VI's as described in the KnowledgeBase article in the following link:

The primary difference from the article is that the data item published using the Publish Data.vi, will follow the following URL convention:
lookout:\\machinename\LV\Blockname\Itemname

The alternative way would be to use either the UDP or TCP VI's and make your own protocol for
transmitting the data.
