IO-Link is a point-to-point communications standard for automation technology. IO-Link permits integrated communication at all levels, from sensors and actuators through superordinated controllers (PLCs) and beyond to the control level. An intelligent field device can transmit data about its status, energy consumption, and the process via this interface. At the same time, parameters of the controller may be modified and then transferred to the product.
The intelligent field device is both supplied with power and integrated into the system via the IO-Link connection. The device is connected to the so-called IO-Link master via the IO-Link cable and from there is connected to the controller. This substantially reduces the cost of cabling in the system. Parameterization of the devices is saved in the superordinate automation system. If a field device is exchanged, the previous parameters can be transferred to it quickly via IO-Link.
The IO-Link master and the field device are connected by an unshielded three-core cable that is at most 20 meters long.
The following products are equipped with an IO-Link interface:
IO-Link and Industrial Ethernet permit integrated communication at all levels, from sensors and actuators through superordinated controllers (PLCs) and beyond to the control level.
IO-Link is a point-to-point communication standard, while Ethernet is based on a bus system. Using Ethernet, multiple participants can communicate directly with each other. Unlike IO-Link, Ethernet does not need an additional IO-Link master for this purpose.
The following products have IODDs:
