Abstract

See full text

A machine tool includes two independent sequence programs that monitor status of safety signals and first and second CPUs that respectively activate the sequence programs. By a configuration in which the second CPU executes monitoring processing at different execution cycles predetermined for the sequence programs, CPU loads in monitoring of status of safety signals are reduced.
