Application of the device-specific blocks for IO-Link

  • 文档
  • 涉及产品
This application uses a concrete example to illustrate the simple connection of Siemens IO-Link devices to a SIMATIC S7-CPU using the Library for IO-Link

Systematic diagnostic concepts and efficient handling of parameter data are demanded in automation technology on all levels. It is imperative here that sensors and switching devices are integrated into the automation compound.
Communication IO-Link offers new possibilities through intelligent connection of sensors and switching devices to the control level. Main topics are switching, protecting and monitoring on field level.
The IO-Link system consists of an IO-Link master and one or several IO-Link devices (sensors or actuators). The IO-Link master works as interface for superimposed control and controls the communication with the connected IO-Link devices.

The application illustrates the usage of the Library for IO-Link (LIOLink) using three scenarios with SIRIUS IO-Link components. The following scenarios are realized for various IO-Link master and PNIO controllers:

  1. Simple reading and writing of data records.
  2. Generating a program alarm using a diagnostic data record.
  3. Save and restore the configuration parameters.

The operation is handled via a WinCC user interface.
