6-8 Offline Debugging
Offline debugging allows you to debug a program when you are not connected online to a Safety CPU
Unit.
You can debug on a Simulator to check control program logic before transferring the project to the
Safety CPU Unit.
WARNING
Although the Simulator simulates the operation of the Safety CPU Unit,
there are difference from the Safety CPU Unit in operation and timing.
After you debug the safety program on the Simulator, always check op-
eration on the physical Safety CPU Unit before you use the user pro-
gram to operate the controlled system.
Accidents may occur if the controlled system performs unexpected op-
eration.
Precautions for Correct Use
Simulation of the operation of the Safety CPU Unit cannot be linked with the operation of the
NJ/NX-series CPU Unit.
Additional Information
Refer to A-16 Differences in Checking Operation between the Simulator and Safety CPU Unit
on page A - 104 for the differences between the Safety CPU Unit and the Simulator.
6-8-1 Offline Safety Program Debugging
To debug a safety program, it is best to simulate the safety program on the computer first to check the
operation logic and parameter settings.
This is called offline debugging.
Simulation Procedures
Use the following procedure to start the Sysmac Studio and connect to the Simulator.
1
Start the Sysmac Studio and create a project.
2
In the Multiview Explorer, select the target Safety CPU Unit in the Controller Selection Box.
3
Use the Sysmac Studio to set the Controller Configurations and Setup and create a safety pro-
gram.
4
Select Build Controller from the Project Menu to build the program.
Additional Information
You cannot connect to the Simulator if the program is not built.
