Common and Smart Sensor Profiles for IO-Link

  • Entry
  • Associated product(s)
The IO-Link community defined device profiles to standardize the access from the user program of a controller to IO-Link devices. This library consists of blocks for standardized access using the Common and Smart Sensor profiles.

The "Common Profile" device profile provides uniform information for identification and diagnosis of the IO-Link device. It is generally valid for IO-Link devices.

The "Smart Sensor Profile" device profile contains the two subprofiles of the switching (adjustable switching sensors) and measuring (measurement data channel) profiles, i.e. switching points or measured values are transmitted with these sensor profiles.

Content of the library
 

 IO-Link blockFunctionality 
 IoIIdentAndDiagThe function block reads and acyclically writes identification and diagnostic data and outputs the status of the connected IO-Link device.
 IoLAdjSwitchingSensorThe function block is used to set or teach the setpoint and to change the switching point logic of adjustable switching sensors (AdSS).
 IoLMeasuredDataChannelWith this function block, measured values of the sensors can be acquired cyclically. The measured raw values of the sensors are processed and are available as REAL or DINT measured values at the respective outputs.

Scope of the library

The library is released for the following IO-Link masters:

  • ET 200SP CM 4xIO-Link (6ES7137-6BD00-0BA0)
  • ET 200AL CM 4xIO-Link (6ES7147-5JD00-0BA0)
  • ET 200pro EM 4 IO-LINK HF (6ES7147-4JD0-0AB0)
  • ET200ecoPN IO-Link Master (6ES7148-6JD00-0AB0)
  • S7-1200 SM 1278 4 IO-Link (6ES7278-4BD32-0XB0)
  • ET 200MP CM 8xIO-Link (6ES7547-1JF00-0AB0)
