Yes, but not ML1500:
For SNS, we are looking at the A-B ControlLogix PLC,
accessed via Ethernet.
It's using the "EtherNet/IP" (Industrial Protocol),
a TCP-encapsulation of ControlNet/CIP
together with A-B specific extensions for accessing
the tags (variables) of the ControlLogix PLC.
I don't know if this will help you with the ML1500,
I'm pretty sure that it won't work out of the box.
