Global Variables Array (ru)
- 9 years ago.
MyCNC software supports Global Variables Array. Values of this array represent current state and configuration of CNC control. There is access to this Array from MyCNC software, GUI components, G-code program, PLC procedures, 3rd party software through Server API etc. Values of this array can be used for inter-process communication as well.
