Safety task inoperable

What does 14-7 mean?

The safety logic is invalid, which can be caused by a logic mismatch between the primary controller and safety partner, a watchdog timeout, or memory corruption. This prevents the safety task from executing correctly and may require re-downloading the program.

• Safety logic is invalid
