[Design Precautions]
WARNING

The Ethernet interface module is not suitable for operation on a safety fieldbus.
The Ethernet interface module only generates non-safety-related fieldbus data (status bytes) for control
and diagnostics purposes.

Do not use non-safe data from an Ethernet interface module for safety related applications.
With the Ethernet interface module it is possible to integrate non-safe data into the logic editor such that
the safety function of the MELSEC-WS safety controller is compromised. Never implement the Ethernet
interface module into a MELSEC-WS safety controller without having this danger checked by a safety
specialist.
