3.2 Communication Example of Safety
Communication Function
This section describes the communication example of the system using the Safety CPU.
System configuration example
The following system configuration is used to explain communications using the Safety CPU.
System configuration
• Power supply module: R61P
• Safety CPU: R08SFCPU
• Safety function module: R6SFM
• Simple Motion module: RD77GF16
• Input module: RX10
• Output module: RY10R2
• Remote I/O module with safety functions (main module): NZ2GFSS2-32D
• Remote I/O module with safety functions (extension module): NZ2EXSS2-8TE
In this program example, I/O devices are connected to X0, X1 (double input) and Y0, Y1 (double output) of the remote device
station.
