5 SAFETY APPLICATION CONFIGURATION EXAMPLES
5.2 System to Which Multiple Safety CPUs are Connected
5.2 System to Which Multiple Safety CPUs are
Connected
This section describes a configuration example of a safety application performs safety communications using three Safety
CPUs.
System configuration
This section describes a safety application using the following system configuration.
In the figure above, "N" means network number, while "S" means station number. For example, "N1" means network number
1, while "S0" means station number 0.
*1 This sets parameters and programs.
*2 They are safety input device such as emergency stop switch, safety switch, light curtain, laser scanner, and mat switch.
*3 They are safety output device such as safety relay and MC.
*4 They are general input device such as reset switch, start switch, and stop switch.
The following table shows definitions of the symbols used in this chapter.
