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

Limitations:

• None

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.
