MELSEC-WS
Data sets
45
4.1.1 Logic results
Logic results generated by the logic editor of the CPU module can be made
available to the network. Up to 20 bytes are available where each bit represents one
logic result from the logic editor.
Data set 1 containing the logic results can be customized. For detailed information
see Section 4.4.
4.1.2 Module and EFI input and output values
The Ethernet interface module can transmit all input and output states of all
MELSEC-WS modules and EFI devices connected to the MELSEC-WS safety
controller into the network. Data set 1 containing the input and output values and the
EFI information can be customized. For detailed information see Section 4.4.
Module input and output states
The input and output states of the modules are transmitted using one byte for each
module’s inputs and one byte for each module’s outputs where each bit represents
the state of one input or output (on/off).
EFI system information
The WS0-CPU1 and WS0-CPU3 have 2 EFI interfaces. An EFI interface is a safe
communication interface between SICK devices. It allows to

read out information from the safety devices (e.g. SICK C4000, S3000)

transfer commands to the safety devices
The Ethernet interface module allows these EFI devices connected to the WS0-
CPU1 and WS0-CPU3 to transmit their data into the network.
It is only possible to select the EFI data in byte arrays. 4 byte arrays for each
connected EFI device are available. Some of the data contents are reserved and
can not be used at the programmable controller.
Further information about the properties, functions and benefits of the EFI interfaces
can be found in the Safety Controller User’s Manual.
4.1.3 Routing of data from a second network
If your MELSEC-WS safety controller contains two network modules, it is possible to
route information received by the first network module from one network (e.g. from a
programmable controller) into a second network via the second network module
(e.g. to an HMI) and vice versa.
