About NE1A-series Safety Network Controllers Section 1-1
Safety outputs The NE1A-SCPU01(-V1)(-EIP) and NE1A-SCPU02(-EIP) both sup-
port eight safety outputs.
7-4
Output circuit diagnosis Test pulses are used to check the NE1A-series Controller’s internal
circuits, external devices, and external wiring.
Overcurrent detec-
tion/protection
To protect the circuit, the output is cut off when an overcurrent is
detected.
Dual Channel Mode Both of two paired outputs can be set into a safety state when an
error occurs in either of the two paired local outputs without depend-
ing on the user program.
DeviceNet Communications
Safety Master A master-slave relationship is established for each connection on the
DeviceNet Safety Network separate from the Master-Slave commu-
nications on the DeviceNet Standard Network. This enables the
NE1A-series Controller to be the safety master to control the con-
nections.
4-4
Safety Slave An NE1A-series Controller can also operate as a DeviceNet Safety
Slave, and the Controller’s internal status information as well as a
specified area of I/O can be allocated in the Safety Master.

Safety I/O communications
operating mode for commu-
nications errors
The operating mode to use for safety I/O communications when a
communications error occurs can be selected.
• Automatic recovery (previous function).
• Stop only the connection where the error occurred.
• Stop all connections.
4-4
Standard Slave An NE1A-series Controller can also operate as a Standard Slave,
and the Controller’s internal status information as well as a specified
area of I/O can be allocated in the Standard Master.
4-6
Explicit messages Explicit messages can be used to read an NE1A-series Controller’s
status information. In addition, explicit messages set from the
Network Configurator can be sent from the user program.
SECTION 6
Automatic baud rate detec-
tion
The NE1A-series Controller’s baud rate can be set automatically to
match the baud rate of the network master.
4-1-1
DeviceNet Communications Disable (Standalone)
DeviceNet communications
disable (Standalone) set-
ting
An NE1A-series Controller can be used as a Standalone Controller
by disabling the Controller’s DeviceNet communications.

System Startup/Error Recovery Functions
Error history Errors detected by the NE1A-series Controller are recorded along
with the Controller’s total operating time at the point that the error
was detected.
12-4
Online monitoring The NE1A-series Controller’s internal status information and I/O data
can be monitored online from the Network Configurator.

Other Functions
Configuration lock The configuration data stored in the NE1A-series Controller can be
locked to protect the data after it has been downloaded and verified.
9-1
Reset The NE1A-series Controller can be reset from the Network Configu-
rator.
9-2
Password A password can be set to prevent unintended or unauthorized
access to the NE1A-series Controller.
