The following examples illustrate safety control systems using NE1A-series
Controllers.
• Safety Control System with an NE1A-series Safety Master
• System Combining an NE1A-series Safety Control System and a Stan-
dard PLC Monitoring Control System
• System Combining a Distributed Safety Control System with Multiple
NE1A-series Controllers and a Centralized Monitoring System Using
Standard PLCs
• Standalone NE1A-series Controller System
• Connection with a Network Configurator
This system uses the NE1A-series Controller as a Safety Master and estab-
lishes a 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.
The NE1A-series Controllers support two protocols, single cast and multicast
(broadcast), for safety I/O connections.
