OS-Wire
OS-Wire is the OSAI propriety communication bus, enabling a very high performance connection between the CNC and other devices, such as drives and digital and analogue modules.
It combines a CNC master with the slave units in a multi-drop topology network. A clock generated by the CNC, received and used by each slave module, synchronizes the communication. The outstanding performance allows the exchange of a large amount of data in real-time, enhancing the control of the machine with a huge advantage in accuracy and speed. The digital command to the motion controller avoids the inaccuracies of traditional analogue control caused by the analogue component drift and the effect of noise on signals. A unique cabling system for axes and I/O reduces wiring costs and minimizes installation and maintenance.
- Data transfer speed: 90 Mbaud
- A 32 bit word is read in 1 μs
- Memory mapping of all slave modules to be accessed by the CNC
- Real-time access to all the slave parameters
- Maximum number of connected devices: 64
- Automatic identification of devices, parameter changes and firmware downloaded via communication Bus
- Fast backup/restore of all the parameters resident on the Master
