At present the enterprise is in the course that number wisdom changes development, need is of all kinds measure sensor, carry out implement, have more efficient, more agile property. Sensor, carry out implement future needs to be inside very short time, can quicker remote control, promotion work efficiency. To satisfy the requirement of automation factory, IO-Link emerge as the times require.

"IO-Link is called to be to lead to sensor and carry out implement last pace, last meters of technology that is known as automation " . IO-Link is a kind of serial communication agreement with bit righter place, it is tradition or intelligence sensor is mixed carry out implement compositive the technology of low cost communication interface in automation system. "Have " IO-Link " communication interface, can make spot sensor can suit to revise the need that parameter sets simple and easily, quickly better, in producing a course you can have huge flexibility " .

IO-Link follows the newest standard of IEC 61131-9.

IO-Link isOrder systems of pair of drop news report, not be spot bus line!

IO-Link supports COM 1 = 4.8 Kbaud, COM 2 = 38.4 Kbaud, COM 3 = 230.4 Kbaud

Farthermost transmission distance is IO-Link 20m.

IO-Link system divides composition by 3:

① IO-Link advocate station module (IO-Link Master)

② IO-Link equipment / from station module (IO-Link Devices/Hub)

Cable of ③ IO-Link wire (IO-Link Cables)

Among them, the sensor that IO-Link equipment includes the site and carry out implement, they take IO-Link interface oneself; If the sensor of the spot is mixed,carry out implement without IO-Link function, also can mix in these sensor carry out implement on installation IO-Link Hub, in order to facilitate they have IO-Link function.

IO-Link wire cable is the 3 core of a kind of standard or cable of 4 core wire.

IO-Link advocate station module has or interface of a few IO-Link, each IO-Link equipment / from station module, through wire cable join arrives on an IO-Link interface.

IO-Link main advantage:

① Plug and Play, standardize wire cable, reduce interface sort significantly

② sensor / carry out implement with the successive communication between controller

③ supports online information to diagnose, shorten debug time, support dynamic parameter to allocate

④ bears compositive equipment label

⑤ volume is minor, implementation intelligence sensor and carry out implement miniaturization

⑥ intelligence corresponds, reduce trival job, promotion efficiency
