The NE1A-SCPU01(-V1)(-EIP) and NE1A-SCPU02(-EIP) both sup-
port eight safety outputs.
circuits, external devices, and external wiring.
To protect the circuit, the output is cut off when an overcurrent is
detected.
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.
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.
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.
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.
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.
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.
The NE1A-series Controller's baud rate can be set automatically to
match the baud rate of the network master.
An NE1A-series Controller can be used as a Standalone Controller
by disabling the Controller's DeviceNet communications.
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.
The NE1A-series Controller's internal status information and I/O data
can be monitored online from the Network Configurator.
The configuration data stored in the NE1A-series Controller can be
locked to protect the data after it has been downloaded and verified.
The NE1A-series Controller can be reset from the Network Configu-
rator.
A password can be set to prevent unintended or unauthorized
access to the NE1A-series Controller.
