Communication with sensors and actuators
IO-Link is the first interface for communication with sensors and actuators and is an international standard .
At OEM Automatic , we are involved in the development of the automation industry , and we want to help you develop and streamline your process . This article explains IO-Link in detail and the products that we offer .
WHAT IS IO-LINK ?
In short , IO-Link is an interface that simplifies communication with sensors and actuators .
WHAT MAKES IO-LINK DIFFERENT TO OTHER INTERFACES ?
IO-Link is different from most similar interfaces as it is standardised internationally , making this their most prominent feature .
So , there is no need to think about whether different components from different manufacturers are compatible .
HOW IO-LINK WORKS
The pyramid below shows how different products can communicate to the same master , which passes this information on to software , which then refines the information . It is also possible to send information directly from sensor level to software .
LEVEL 3 : THE INFORMATION IS PROCESSED / SENT
The information from level 1 or 2 is used to make calculations regarding efficiency , operating time and future maintenance with the help of software , that compiles the information . From here , you can also control and configure your devices further down the chain .
LEVEL 2 : INFORMATION COLLECTED
Information is collected with the help of a master . For example , a PLC can be placed in the industry , this means that you do not have to configure your long wiring to the machine level . You can also configure the sensors remotely , so you don ’ t have to go out to the site to adjust the settings .
