Safety Network Controller Overview Section 1-2
1-2-2 NE1A Series Features
Safety Logic Operations
In addition to basic logic functions, such as AND and OR, the NE1A-series
Controllers also support application function blocks, such as Emergency Stop
Pushbutton Monitoring and Safety Gate Monitoring, that enable various safety
applications.
User-defined Function Blocks
Previously prepared logic functions and function blocks can be combined to
create a user-defined function block using the Network Configurator version
1.5
@ or higher. This can be used to standardize functions that are used fre-
quently to facilitate reusing them. Passwords can also be used to protect the
programming inside the function blocks by making them “black boxes.”
Local Safety I/O
• A total of 24 local safety I/O points are supported by NE1A-SCPU01(-
V1)(-EIP): 16 input terminals and 8 output terminals.
• A total of 48 local safety I/O points are supported by NE1A-SCPU02(-
EIP): 40 input terminals and 8 output terminals.
• Faults in external wiring can be detected.
• Dual Channel Mode can be set for pairs of related local inputs.
When Dual Channel Mode is set, the 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 outputs. When
Dual Channel Mode is set, the NE1A-series Controller can evaluate the
output data patterns.
DeviceNet Safety Communications
• As a Safety Master, a Pre-Ver. 1.0 NE1A-series Controller can perform
safety I/O communications with up to 16 connections using up to 16 bytes
per connection.
• As a Safety Master, any NE1A-series Controller other than a Pre-Ver. 1.0
NE1A-series Controller 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 Controller 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 Controller 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 (Controllers that Support EtherNet/IP Only)
As an EtherNet/IP Target, the NE1A-series Controller can perform standard
I/O communications with one EtherNet/IP originator for up to two connections
using up to 16 output bytes and 128 input bytes per connection.
Disabling DeviceNet Communications (Standalone)
An NE1A-series Controller can be used as a Standalone Controller by using a
setting to disable the Controller's DeviceNet communications.
Configuration with a Graphical Tool
• A graphical tool is provided for both network configuration and logic pro-
gramming. It enables easy configuration and programming.
