8-9 Performing Safety Validation and
Operation
This section describes the procedure for safety validation testing. Safety validation testing is used to
confirm that all safety functions and all Safety Control Units meet the required specifications of the
safety system. If safety validation testing demonstrates that the safety controls meet the required spec-
ifications of a safety system, the safety application data is appended with confirmation information
through a process called safety validation.
When you perform safety validation on a Safety CPU Unit that is operating in DEBUG mode, the safety
application data is saved in the non-volatile memory of the Safety CPU Unit.
This section describes how to perform safety validation and start operation after you have debugged
the safety programs.
You must perform safety validation before you change the Safety CPU Unit to RUN mode and start any
safety control system that uses safety application data
*1
that is created in the Sysmac Studio.
You perform safety validation after you perform safety validation testing with the Safety CPU Unit in
DEBUG mode (RUN) to make sure that all safety functions operate as intended.
To perform safety validation, it is necessary that the Safety CPU Unit be in DEBUG mode.
Additional Information
You can perform change management on the safety application data before you perform safety
validation after debugging is completed, or after you perform safety validation. Refer to A-4
Change Tracking on page A-60 for details.
8-9-1 Performing Safety Validation
*1. The safety application data includes the safety programs and the safety task settings and variables. Refer to 8-1-2 Data
That You Must Transfer before Operation and Data Transfer Procedures on page 8-6 for details.
WARNING
Before you perform safety validation of the safety programs, complete debugging of the safety
programs.
Otherwise, the Safety CPU Unit will start with safety programs that are not fully debugged and
may cause serious personal injury.
Verify the calculated reaction times for all safety chains to confirm that they satisfy the required
specifications.
Serious injury may possibly occur due to loss of required safety functions.
