Mitsubishi Custom API Library and EZSocket
Mitsubishi's Custom API Library (standard on M8/M8V) lets Windows applications in C, C# or C++ read and write programs, files, coordinates, alarms, tool data, variables and PLC devices, with real-time sampling on M800V/M80V. EZSocket is the interface underneath; third-party drivers use TCP 683 by default (not stated in Mitsubishi documents).
