About NE1A-series Safety Network Controllers Section 1-1
1-1-2 Features of the NE1A-series Controllers
Safety Logic Operations
In addition to basic logic functions, such as AND and OR, function blocks such
as Emergency Stop or Safety Gate Monitoring that enable various safety
applications are supported.
Local Safety I/O
• In the NE1A-SCPU01(-V1)(-EIP), a total of 24 local safety I/O points are
supported: 16 inputs and 8 outputs.
• In the NE1A-SCPU02(-EIP), a total of 48 local safety I/O points are sup-
ported: 40 inputs and 8 outputs.
• Faults in external wiring can be detected.
• Dual Channel Mode can be set for pairs of related local input terminals.
When Dual Channel Mode is set, an NE1A-series Controller can evaluate
the input data patterns and the time discrepancy between input signals.
• Dual Channel Mode can be set for pairs of related local output terminals.
When Dual Channel Mode is set, an NE1A-series Controller can evaluate
the output data patterns.
DeviceNet Safety Communications
• As a Safety Master, Pre-Ver. 1.0 Controllers can perform safety I/O com-
munications with up to 16 connections using up to 16 bytes per connec-
tion.
• As a Safety Master, an NE1A-series Controller with unit version 1.0 or
later (including Controllers that support EtherNet/IP) can perform safety
I/O communications with up to 32 connections using up to 16 bytes per
connection.
• As a Safety Slave, the NE1A-series Controllers can perform safety I/O
communications with a maximum of four connections using up to 16 bytes
per connection.
DeviceNet Standard Communications
As a Standard Slave, the NE1A-series Controllers can perform standard I/O
communications with one Standard Master for up to two connections using up
to 16 bytes per connection.
EtherNet/IP Standard Communications (Only Controllers that Support EtherNet/IP)
As an EtherNet/IP target, an NE1A-series Controller can perform standard I/O
communications with up to two connections with a single EtherNet/IP origina-
tor, using up to 128 bytes for input and 16 bytes for output per connection.
DeviceNet Communications Disable (Standalone) Setting
An NE1A-series Controller can be used as a Standalone Controller by dis-
abling its DeviceNet communications.
Configuration with a Graphical Tool
• A graphical tool is provided for both network configuration and user pro-
gramming. It enables easy configuration and programming.
• A Logic Editor can be activated from the Network Configurator.
• Configuration data can be downloaded and uploaded, and devices can be
monitored online via DeviceNet, USB, EtherNet/IP, or the peripheral inter-
face of an OMRON PLC.
