Hello everyone,
I am experiencing a voltage issue between the IO-Link master and IO-Link devices in my new project based on IO-Link communication. The setup involves a STEVAL-IDP004V2 IO-Link master and a STEVAL-IDP003V1 IO-Link slave/device. I have supplied 32V power to the IO-Link master, and the IO-Link slaves are connected via M12 connectors to the IO-Link master ports.
However, I have observed that the voltage supplied from the IO-Link master ports to the IO-Link slaves is insufficient for their operation (it does not come from 32V supply from the IO-Link master ports). Using a multimeter, I measured the voltage at the IO-Link master port pins (L+ and L—), and it ranges between 2V and 4V, depending on the input supply.
Could you please advise on the following:
- How can I resolve this voltage issue to supply sufficient power from the IO-Link master to the IO-Link slaves?
- Is a firmware update for the IO-Link master required in this scenario?
- What other methods can help address the voltage discrepancy between the IO-Link master and slaves/devices?
Thank you so much for your support :)
Best Regards
Rama Salla
