In 2019 we have replaced the embedded Ethernet switch of our M580 PLC range by a more robust one.
To manage this new hardware an OS V2.90 has been published.

This OSV2.90 also fixes some Protuct Change Requests (PCR) and also, resolves some cybersecurity PCRs. A firmware history is availaible in our website schneider-electric.com.
It's possible to upgrade M580 (old hardware) with OS >=V2.90 whatever the UnityLoader version.
