Standalone Safety Control System
The section describes the relationships of the Safety CPU Unit, EtherNet/IP Coupler Unit, and a stand-
ard CPU Unit within the system, and provides details on communications between the Units based on
the following figure.

The safety control system consists of the Safety CPU Unit, Safety I/O Units, and standard I/O Units.
The Safety CPU Unit performs safety controls with Safety I/O Units through "safety process data
communications". (Section (A) in the above figure.)
The Safety CPU Unit, Safety I/O Units and standard I/O Units can perform standard I/O with the Com-
munications Coupler Unit through "standard process data communications". (Section (B) in the above
figure.)
The standard CPU Unit can indirectly monitor the operating status of the safety control system through
"standard process data communications" when the Communications Coupler Unit is connected. (Sec-
tion (C) in the above figure.)
Relationship between Master and Slaves during Safety Process Da-
ta Communications
