OSwire

OSwire is the new transmission digital protocol that exceeds the main competitors reaching a top data transfer rate of 90MBaud. This support allows up to 64 OSwire connected devices and the ability to monitor the internal size of the high frequency peripherals.

The drives and the I/O are simple memory locations that give the big advantage of reading and writing all the specific variables of the peripherals. The real time reading of some items such as electrical power and following error, allows to auto-tune the machine without using any external sensor.

“Fine” hardware synchronisation: the synchronisation between the master (the CNC) and all the devices is generated totally by the hardware. This allows to interpolate more axes with a great accuracy and precision without influencing the data speed rate even if the number of devices increases. Infact, the same DSP plugged in OSAI’s drives receives the clock directly from the CNC, guaranteeing in this way a “fine” synchronisation of the single loop inside each single drive.

Reduced wiring: OSwire allows to connect different types of devices to the CNC. OSAI supplies I/O digital and analogue modules using the same Protocol, simply by wiring a single cable it will be possible to interface: CNC, I/O modules, encoder inputs, analogue I/O and especially the new digital drives OS3.

• Data transfer speed: 90 Mbaud
• Read of 16 bit word in 1,5 µs
• Each slave module is seen by the CNC as a memory location
• Real-time access of all the slave parameters
• Maximun number of connected devices: 64
• Automatic identification of the devices, parameter charges and via Bus firmware download
