2. On safety
This chapter deals with your own safety and the safety of the equipment operators.
 Please read this chapter carefully before working with an Ethernet interface
module.
2.1 Qualified safety personnel
The Ethernet interface module may only be installed, commissioned and serviced by
qualified safety personnel.
Qualified safety personnel are defined as persons who…
 have undergone the appropriate technical training
and
 have been instructed by the responsible machine operator in the operation of the
machine and the current valid safety guidelines
and
 have access to the manuals of the Ethernet interface module and safety controller
and have read and familiarized themselves with them.
2.2 Correct use
The Ethernet interface module can only be operated with a MELSEC-WS safety
controller.
The Ethernet interface module does not have a dedicated voltage supply.
ATTENTION
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.
The Ethernet interface module may only be used by qualified safety personnel and
only on the machine where they have been installed and initialized by qualified safety
personnel in accordance with the manual.
