System Combining a Distributed Safety Control System with Multiple NE1A-series
Controllers and a Centralized Monitoring System
This system uses each NE1A-series Controller as a Safety Master and estab-
lishes a Safety Remote I/O System with Safety Slaves.
Each NE1A-series Controller also simultaneously functions as a Standard
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.
In the DeviceNet Safety System, multiple Safety Masters can be connected
on the same network. Therefore, the distributed safety control blocks can be
monitored centrally on the same network.
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.
