ifm IOLink

---

Description

This adapter enables the integration of IO-Link sensor data produced by an ifm IO-Link Master (e.g., AL1350) with Apache StreamPipes. To use this adapter, you need to configure your IO-Link master to publish events to an MQTT broker. This can be achieved through a REST interface or via the browser at http://##IP_OF_IO_LINK_MASTER##/web/subscribe. For detailed instructions, please refer to the ifm documentation.

Requirements

The JSON events should include the following information:

• deviceinfo.serialnumber
• Only the pdin value is required for each port (e.g., port[0]).
• The event timer[1].datachanged can be used as a trigger. Using this adapter, you can create a stream for sensors of the same type.

Restrictions

This version supports a single IO-Link master. If you want to connect multiple masters, they must have the same setup. If you have different requirements, please inform us through the mailing list or GitHub discussions.
