Introduction to the NE1A-series Safety Network Controllers
The NE1A-series Safety Network Controllers provide various functions, such
as safety logic operations, safety I/O control, and a DeviceNet Safety protocol.
The NE1A-series Controller allows the user to construct a safety control/net-
work system that meets the requirements for Safety Integrity Level (SIL) 3
according to IEC 61508 (Functional Safety of Electrical/Electronic/ Program-
mable Electronic Safety-related Systems) and the requirements for Safety
Category 4 according to EN 954-1.
In the example system shown below, the safety control system implemented
with an NE1A-series Controller and the monitoring system implemented with
a Standard PLC are realized on the same network.
• As a Safety Logic Controller, the NE1A-series Controller executes safety
logic operations and controls local I/O.
• As a DeviceNet Safety Master, the NE1A-series Controller controls the
remote I/O of DeviceNet Safety Slaves.
• As a DeviceNet Standard Slave, the NE1A-series Controller communi-
cates with the DeviceNet Standard Master.

Safety I/O Control
The PLC system monitors the
NE1A (i.e., the safety control
system) using DeviceNet I/O
communications and explicit
messages.
The DeviceNet Safety
System controls remote I/O.
