IO-Link,known as‘Input/Output Link’,is not a fieldbus,but an open standard for serial communication(IEC 61131-9).It breaks the information barriers between traditional sensors and control systems,realises two-way communication and data exchange between devices,and brings a revolutionary change for industrial automation.
First,where are the advantages of IO-Link?
1、Strong anti-interference ability:In traditional data transmission,the type of signal passed between the sensor and the controller is analogue,while IO-Link adopts all-digital transmission,so it has strong anti-interference ability.
2,no signal loss:the traditional data transmission process,need to go through the digital-analog-analogue-digital conversion,while IO-Link is a fully digital transmission,no data type conversion,so there is no loss of precision.
3,simplify the wiring network:IO-Link simplifies the circuit connection,only a standard cable is required,which greatly reduces the difficulty of wiring layout,making the wiring network more simple.
4,easy to replace:IO-Link so that the system has a parameter auto-configuration function,when the replacement of the same type of sensor/actuator,will automatically configure the parameters to the new sensor/actuator.
5,easy to operate:the use of IO-Link technology,the system has a remote configuration function,the traditional on-site operation of the configuration keys removed,replaced by remote operation.
6,disconnection monitoring:IO-Link so that the point-to-point connection of digital quantities have the ability to dialogue,that is,the system has a greater ability to exchange data,so the system has the ability to diagnose,when there is a disconnection,it will be alarmed.
7、Intelligent devices:The addition of IO-Link technology enables sensors to transmit multiple signals at the same time,releasing all the potential of the sensors,so the devices are more intelligent and make wiring and work easier.
Second,what are the application scenarios of IO-Link?
