5-2 Standard Target Function
5-2-1 Standard I/O Communications as Standard Target
An NE1A-series Controller can function as a Standard Target.
The NE1A-series Controller’s internal status information is also included in
the data allocated to the Standard Originator, and so a monitoring system
using a PLC can be established.
The following steps are required in order for an NE1A-series Controller to per-
form standard I/O communications as a Standard Target.
1. Creation of I/O data (Target I/O) to use as a Standard Target
2. Registration in the Standard Originator
3. Connection settings in the Standard Originator
For details on how to make the settings, refer to the DeviceNet Safety System
Configuration Manual (Cat. No. Z905).

IMPORTANT For an NE1A-series Controller, do not set a connection through an open net-
work.
5-2-2 Creating I/O Data (Target I/O) to Use as Standard Target
The I/O data to be used for the Standard Target must be created in order for
an NE1A-series Controller to perform standard I/O communications as a
Standard Target.
• Target I/O blocks can be created for a maximum of 2 connections.
• The maximum data size for Target I/O is 128 input bytes or 16 output
bytes.
