MELSEC-WS
4. Data sets
The Ethernet interface module allows the MELSEC-WS safety controller to send and
receive non-safety related data to and from the external fieldbus system for control
and diagnostics purposes.
Note
ATTENTION
In this manual, the data exchanged between the MELSEC-WS safety controller and
the respective network will be considered always from the network master
(programmable controller) point of view. Therefore data sent from the MELSEC-WS
safety controller into the network will be referred to as input data while data received
from the network will be referred to as output data.
Do not operate an Ethernet interface module on a safety fieldbus!
The Ethernet interface module is not suitable for operation on a safety fieldbus. It
does not support any safety mechanism, which would be mandatory to
communicate within a safety network.
Configuration of the Ethernet interface module is performed using the Setting and
Monitoring Tool on a PC or notebook connected to the CPU module over RS-232
interface or connected to the Ethernet interface module over Ethernet TCP/IP.
Configuration data can be exported, imported, and saved.
The safety relevant logic of the MELSEC-WS safety controller operates
independently from the Ethernet interface module. If however the MELSEC-WS
safety controller has been configured to integrate non-safe information from the
fieldbus into the logic editor, a decoupling of the Ethernet interface module can result
in availability problems.
An Ethernet interface module can only be operated on a MELSEC-WS safety
controller. It does not have a dedicated voltage supply. It is possible to use two
network modules per system.
The Ethernet interface module is fitted in a 22.5 mm wide housing for 35 mm rails in
accordance with EN 60715.
