Procedure for operating an IO-Link master unit in a network of automation technology

摘要

In a method for operating an IO-Link master unit in a network of automation technology, which is connected to a control PLC and several IO-Link devices, whereby the IO-Link master unit is connected to the IO-Link devices (IO-Link devices) If several ports P1-Pn are provided on the IO-Link master unit, a program module is provided in the IO-Link master unit, which serves as an abstraction layer, the data of the IO-Link devices not depending on the port, but depending on a unique device class ID can be sent to the PLC controller.
