Page 37: Features Of The Ne1A-Series Controllers
As an EtherNet/IP target, an NE1A-series Controller can perform standard I/O communications with up to two connections with a single EtherNet/IP origina- tor, using up to 128 bytes for input and 16 bytes for output per connection. DeviceNet Communications Disable (Standalone) Setting An NE1A-series Controller can be used as a Standalone Controller by dis- abling its DeviceNet communications.
Page 38: Functional Overview
• 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.

Page 41: System Configuration
DeviceNet Safety System Overview DeviceNet is an open-field, multi-vendor, multi-bit network, which combines the controls in the machine and line control levels with information. The DeviceNet Safety network adds safety functions to the conventional DeviceNet standard communications protocol. The DeviceNet Safety concept has been approved by a third-party organization (TÜV Rhineland).
Page 42: Example System Configurations
Safety Remote I/O System with Safety Slaves. The Pre-Ver. 1.0 Controllers can perform safety I/O communications as a Safety Master for a maximum of 16 connections (16 Slaves) with up to 16 bytes per connection. Controllers with unit version 1.0 or later (including Controllers that support EtherNet/IP) can perform safety I/O communications as a Safety Master for a maximum of 32 connections (32 Slaves) with up to 16 bytes per connection.
Page 43 Slave. As a Standard Slave, the NE1A-series Controller enables standard I/O com- munications for a maximum of two connections with up to 16 bytes per con- nection. Four protocols (i.e., Poll, Bitstrobe, COS and Cyclic) are supported for I/O connections. The NE1A-series Controller cannot operate as a Stan- dard Master.
Page 44 Slave and standard I/O communications are performed with the Standard Master. The Safety Control System can be monitored using a Standard PLC by allo- cating the NE1A-series Controller’s status information (general status, local I/O error status, or other information) or logic operation results in the Standard PLC.
Page 45 Also, safety I/O communications between NE1A-series Controllers can be performed as illustrated in the following diagram. In the diagram, NE1A #2 is set as the slave of NE1A #1 safety connections to perform safety I/O commu- nications. The NE1A-series Controller functions as a Safety Master, Safety Slave, and Standard Slave simultaneously.

Page 154 ■ Calculating the Total ON Time with 1.5-s ON Pulses In figure C, the bit is actually ON for 1.5 s × 2 = 3 s, but the bit is ON four times when the status is checked, so the total ON time is measured as 4 s.

Page 157: Safety Inputs
The NE1A-SCPU01(-V1)(-EIP) is equipped with 16 safety input terminals. The NE1A-SCPU02(-EIP) is equipped with 40 safety input terminals. By selecting the setup and wiring based on the types of input devices to be connected or the safety level to be achieved, the NE1A-series Controller can flexibly handle various applications.
Page 158: Input Channel Mode Setting
Select the test output terminal to use as the test source for the safety input when the input channel mode is set to Test pulse from test output. If short cir- cuit detection between input wiring lines is necessary, specify a different test output terminal.
Page 159: Dual Channel Mode Setting
For two inputs set in Dual Channel Mode, the time is monitored from a change in the value of one input to a change in the value of the other input (discrep- ancy time). When the value of the other input does not change within the set discrepancy, it is regarded as an error.
Page 160 Error Status Status Note The NE1A-series Controllers supports function blocks with functionality equiv- alent to Dual Channel Mode. If Dual Channel Mode is set in a function block, then the safety input terminal can be set to Single Channel Mode.

IMPORTANT When the power supply is interrupted in IDLE Mode, the NE1A-series Control- ler will not start in RUN Mode at the next startup even though Automatic Exe- cution Mode is set and the configuration is locked. Make sure to turn OFF the power supply in RUN Mode.
Page 248 Test the system before starting actual opera- tion. (2) The maximum program execution delay is 20 seconds. Program execu- tion will start in 20 seconds even if all safety I/O communications have not started normally due to problems in the network, settings, or communica- tions.

NE1A-series Controller will turn OFF the outputs. Low Power Supply Voltage for I/O Circuits If the power supply voltage for input drops to 85% of the rated voltage or lower when the power supply voltage for the internal circuit is normal, the NE1A- series Controller will continue operation but will stop refreshing inputs.

The calculations shown here are assumed to satisfy the following conditions: • The configuration is correct. • The power has been turned ON, the SNC self-diagnostic function has been completed, and the NE1A-series Controller is in RUN Mode. • The necessary Safety Slaves have been added to the system.
Page 253: Operational Flow And Cycle Time
IMPORTANT For a Controller that supports EtherNet/IP, the maximum cycle time is 60 ms. If a cycle time of more than 60 ms is set, correct the connection settings and user applications and change the system configuration so that the cycle time...
Page 254: Startup Time
Note (1) With NE1A-series Controllers with unit version 2.0 (including Controllers that support EtherNet/IP), an online delay time of 5 s is added after the initialization has been completed to allow time for other devices to start. (2) After the initialization has been completed, the NE1A-series Controller checks for duplicated addresses on the DeviceNet network and then joins the network (i.e., goes online).
Page 255 ON, program execution is slower for unit version 2.0 (in- cluding Controllers that support EtherNet/IP) than for unit version 1.0. With a program in which a timer is started simultaneous with the start of NE1A-series Controller program execution, the time from when the power is turned ON until the timer times out is extended.
