Well, from their FAQ, they say, "The Modbus protocol was transferred from Schneider Electric to Modbus-IDA in April 2004, signaling a commitment to openness. The specification is available free of charge for download, and there are no subsequent licensing fees required for using Modbus or Modbus TCP/IP protocols." I'm poking around now to see if maybe there's some kind of client daemon already available out there that I could perhaps use Nagios to pull output from. Whatever I manage to rig up I'll put something up on nagiosexchange for any others that might need it.
