8.2.5 Safety program (safety programmable controller)
Create a safety program of the safety programmable controller.
・ When the safety inputs SA\X0 (safety sensor 1A), SA\X4 (emergency stop switch 1), and SA\X14 (emergency
stop switch 2) are ON, the safety internal relay SA\M10 turns ON.
・ When the safety input SA\X2 (safety sensor 1B) is ON, the safety internal relay SA\M11 turns ON.
・ When the safety inputs SA\X10 (safety sensor 2A), SA\X14 (emergency stop switch 2), and SA\X4 (emergency
stop switch 1) are ON, the safety internal relay SA\M20 turns ON.
・ When the safety input SA\X12 (safety sensor 2B) is ON, the safety internal relay SA\M21 turns ON.
・ When the safety internal relay SA\M10 is ON, the safety outputs SA\Y20, SA\Y30, and SA\Y40 turn ON.
・ When the safety internal relay SA\M11 is ON, the safety outputs SA\Y21, SA\Y31, and SA\Y41 turn ON.
・ When the safety internal relay SA\M20 is ON, the safety outputs SA\Y50 and SA\Y60 turn ON.
・ When the safety internal relay SA\M21 is ON, the safety outputs SA\Y51 and SA\Y61 turn ON.
* In addition, processes such as checking the safety refresh communication status and releasing the safety station
interlock are required.
