I-Link IO-Link master stack

The RT-Labs IO-Link stack I-Link is used for IO-Link master implementations. It is easy to use and provides a small footprint. It is especially well suited for embedded systems where resources are limited and efficiency is crucial. It is written in C and can be run on bare-metal hardware, an RTOS such as rt-kernel, or on Linux. The I-Link stack is supplied with full sources including a porting layer.

Also, C++ (any version) is supported.

RT-Labs I-Link is developed according to specification 2.3:

  • Conformance Class A (Class B upon request)
  • Real Time Class 1

Features

  • Porting layer provided

  • MAX14819 master transceiver supported

  • The sample application currently supports two different devices from IFM:

    • An RFID reader (IFM part number: DTI515)
    • A display device (IFM part number: E30430)

Limitations

  • For support of other IO-Link devices, code have to be added to the application

License

This software is dual-licensed, with GPL version 3 and a commercial license. See LICENSE.md for more details.

Requirements

cmake

  • cmake 3.14 or later

For Linux:

  • gcc 4.6 or later

For rt-kernel:

  • Workbench 2018.1 or later

As an example of a microcontroller we have been using the Infineon XMC4800, which has an ARM Cortex-M4 running at 144 MHz, with 2 MB Flash and 352 kB RAM. It runs rt-kernel, and we have tested it with 2 MAX14819 chips, each with 2 IO-Link ports.
