Related to the IS012100: Safety of machinery-Basic concepts, general principles for design, the position and the ripple effect of the IEC61508: Functional safety of electrical/electronic/programmable electronic safety-related systems is to be considered, when the software is applied to the control. Specially, the logistic system or the large-scale product system, such as the automobile industry and the semiconductor industry, the application of safe programmable controller should be required from the efficient viewpoint in future. Then, the safety management for all the life cycles and the product design meeting the functional safety should be necessary. After product has already been established logically and technically, it is authenticated by third party and applied to the actual working place. Because the functional safety standard is in the high level and the comprehensive scale, the proper consensus between the user side and the establishment side should be created at the introduction of each field.
