Generic EthernetIP
« on: April 02, 2017, 06:37:13 PM »
I don't know if this is currently possible or not.

I am building a low cost machine that will have a number of servo drives doing positioning and some basic IO and am building a HMI in AHMI.  At present there will be a small PLC to talk to the servos and terminate the IO.  The PLC could be eliminated altogether if the drives and IO could be addressed directly over EthernetIP from the PC.  I know that windows is not exactly deterministic but the IO requirements are pretty pedestrian.

Can the AHMI drivers act as a master for EthernetIP/ModbusTCP devices?

The Modbus drivers are masters and can control devices directly.

The Ethernet/IP drivers only implement connected explicit messages and not IO messages, so it cannot control a device directly.
