Can Ignition read data directly from remote I/O communication module?

For example, given a remote I/O set with an EtherNet/IP communication module, can Ignition read the I/O values directly from the communication module, or is a PLC processor required?

Thanks!

Base Ignition drivers cannot but pturmel's Ethernet/IP Driver can, when configured as an E/IP Scanner.

If Modbus TCP is available, you can read directly from a remote I/O device.

Modbus is so ubiquitous that you can safely assume this was already ruled out, or was unsuitable in some way (like, using TCP/IP to transfer I/O).
