Logic Operations
Logic operations
Basic logic operations, such as AND and OR, and function blocks,
such as Emergency Stop (ESTOP) and Safety Gate Monitoring
(SGATE), are supported.
In the Pre-Ver. 1.0 Controllers, up to 128 logic functions and function
blocks can be used in programming.
In the Controllers with unit version 1 or later, up to 254 logic func-
tions and function blocks can be used in programming.

Safety I/O
I/O comments
The user can store any name for each I/O terminal using a maximum
of 32 characters (ASCII).
5-1-1
I/O power monitoring
The NE1A-series Controllers can detect whether I/O power is
supplied within the normal voltage range.
5-1-2
Safety inputs
The NE1A-SCPU01(-V1) supports a 16 safety inputs.
The NE1A-SCPU02 supports a 40 safety inputs.
5-2
Input circuit diagnosis
Test pulses are used to check the NE1A-series Controller’s internal
circuits, external devices, and external wiring.
Input ON/OFF delays
Input time constants between 0 and 126 ms in multiples of the
Controller’s cycle time can be set for Controller’s inputs.
Setting input ON/OFF delays helps reduce influence from chattering
or external noise.
Dual Channel Mode
Time discrepancies in changes in data or input signals between two
paired local inputs can be evaluated.
Test pulse outputs
The NE1A-SCPU01(-V1) supports four independent test outputs.
The NE1A-SCPU02 supports eight independent test outputs.
These are normally used in combination with safety inputs.
They can also be set for use as signal output terminals.
5-3
Current monitoring for
muting lamp (T3, T7 ter-
minal only)
The NE1A-SCPU01(-V1) can detect a disconnection at the T3
terminal.
The NE1A-SCPU02 can detect disconnections at the T3 and T7 ter-
minals.
Overcurrent detection/
protection
An output is blocked when an overcurrent is detected to protect the
circuit.
Safety outputs
The NE1A-SCPU01(-V1) and NE1A-SCPU02 both support eight
safety outputs.
5-4
Output circuit diagnosis Test pulses are used to check the NE1A-series Controller’s internal
circuits, external devices, and external wiring.
Overcurrent detection/
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.
4-5
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.
