IO-Link Diagnostic Channel Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IO-Link systems, diagnostic data from infrastructure components is typically transmitted through the same data channel as device data, making the channel non-transparent and dependent on the infrastructure component, which restricts the use of infrastructure components and requires separate IODDs for devices connected via these components.
Innovation Solution
A separate diagnostic channel is introduced within the IO-Link system, allowing diagnostic data from infrastructure components to be transmitted independently of the data channel, using an apparatus for recording diagnostic data such as sensors or measuring devices, and routed through a distinct communication channel to the IO-Link master, maintaining the transparency of the data channel.

1Loss of information
If diagnostic data from infrastructure components is transmitted through the same data channel as device data, then the data channel can carry all necessary information, but the channel becomes non-transparent and dependent on the infrastructure component
Solution Approach 1:
The communication channel is segmented into two separate channels: a data channel for device data and a diagnostic channel for infrastructure component diagnostic data. This segmentation allows each channel to maintain its specific function and transparency characteristics while ensuring that all necessary information is transmitted without mixing different types of data.
Solution Approach 2:
Diagnostic data transmission is extracted from the data channel and placed into a separate diagnostic channel. This extraction removes the dependency of the data channel on infrastructure components, maintaining its transparency and allowing the same data channel to be used with different infrastructure components.
2Adaptability or versatility
If a separate diagnostic channel is introduced, then the data channel remains transparent, but the system complexity increases
Solution Approach 1:
The diagnostic channel uses the same IO-Link communication protocol and data structure as the data channel, allowing a single communication infrastructure to serve multiple functions. The IO-Link master can handle both device data and diagnostic data through the same protocol framework, reducing the need for separate specialized infrastructure.

AI summary
The invention relates to an IO-Link system comprising at least one IO-Link master (1), at least one IO-Link device (2) and at least one IO-Link-capable infrastructure component (30). The at least one IO-Link master (1) and the at least one IO-Link device (2) are connected via the at least one infrastructure component (30) and exchange data via a data channel (K1). The infrastructure component (30) has an apparatus (61, 62) for recording diagnostic data. A diagnostic channel (K2) is provided in the IO-Link system, via which diagnostic channel (K2) the diagnostic data can be sent and received between the at least one infrastructure component (30) and the at least one IO-Link master (1) separately from the data channel (K1).
