Has anyone had success with the 1794-AENT/B ethernet modules? I have one of the Flex I/O ethernet interface modules with two 8 port analog in modules. I can read the 1794/AENT module information like model, version etc but nothing representing the I/O data.

Sorry to drag up an old thread, Greg, but did you ever find a way to do this? I'm now presented with the same problem, I need access to channel data from a 1794-AENT over its EtherNet/IP interface. Might be open to adding a DeviceNet card if it works.

The way I ended up doing it was by installing an AB PLC in the network and using it as a concentrator. The AB PLC could pole all the different Flex I/O I had on the network and then my National Instruments program would request the data from the PLC. It actually worked very well and I could have multiple PCs running the Labview code all talking to the one PLC. I also could store calibration data in the PLC and then all PCs used the same calibration data.
Hope this helps.

Thanks, Greg. We were hoping to get away with something simpler and cheaper than a PLC, but if that's the only way around it, we'll manage. Thanks for letting me know.

I know this post is old, there is a very cost effect solution for a PLC that can interface to LabVIEW. Look at Velocio.net. They make some FPGA based PLC modules, with a very impressive range of I/O including thermocouple. They can also to PID control.
They can interface with LabVIEW either via ModBus [RS232 Serial] or via simple serial:provided you code this into the PLC.

That's great info, I'll look into it.
Thanks.
