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
- Source repository: https://github.com/rtlabs-com/i-link
- Documentation: https://rt-labs.com/docs/i-link
- RT-Labs (stack integration, certification services and training): https://rt-labs.com
-
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)
- For support of other IO-Link devices, code have to be added to the application

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.
