System Configuration
Section 1-2
System Combining a Safety Control System and a PLC Monitoring Control System
This system uses the NE1A-series Controller as a Safety Master and estab-
lishes a Safety Remote I/O System with Safety Slaves.
The NE1A-series Controller is used as a Standard Slave and standard I/O
communications are performed with the Standard Master. The NE1A-series
Controller simultaneously functions as the Safety Master and a Standard
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.
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 for standard I/O communications.
A Safety System and a Monitoring System can be combined and established
on the same network by using standard devices and safety devices.
IMPORTANT
A maximum total of 64 standard nodes and safety nodes can be connected on
the same network.
The data attributes handled by standard I/O communications and explicit
message communications are non-safety data. The necessary measures for
safety data are not taken for this data during data generation. Therefore, do
not use this data to configure the Safety Control System.
