• The error information can be checked by using the Network Configurator
or the indicators on the front of the NE1A-series Controller.
• The NE1A-series Controller's internal status information can be moni-
tored from a Standard PLC by allocating the information in the Standard
Master. In the same way, monitoring with a Safety PLC is possible by allo-
cating information in the Safety Master.
• An NE1A-series Controller's internal status information can be allocated
in an EtherNet/IP originator and monitored by a Standard PLC. (Possible
only for Controllers that support EtherNet/IP.)
• The NE1A-series Controller's configuration data is protected by a pass-
word set in the Controller.
• The Network Configurator controls access to each project file with a pass-
word.
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 1.0 or later (including Controllers
that support EtherNet/IP), up to 254 logic functions and function
blocks can be used in programming.
The user can store any name for each I/O terminal using a maximum
of 32 characters (ASCII).
The NE1A-series Controllers can detect whether I/O power is
supplied within the normal voltage range.
The NE1A-SCPU01(-V1)(-EIP) supports a 16 safety inputs.
The NE1A-SCPU02(-EIP) supports a 40 safety inputs.
Test pulses are used to check the NE1A-series Controller's internal
circuits, external devices, and external wiring.
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.
Time discrepancies in changes in data or input signals between two
paired local inputs can be evaluated.
The NE1A-SCPU01(-V1)(-EIP) supports four independent test out-
puts.
The NE1A-SCPU02(-EIP) 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.
The NE1A-SCPU01(-V1)(-EIP) can detect a disconnection at the T3
terminal.
The NE1A-SCPU02(-EIP) can detect disconnections at the T3 and
T7 terminals.
An output is blocked when an overcurrent is detected to protect the
circuit.
