Abstract: PLC every one I / O points in the average price up to several tens yuan,reduce the amount of I / O points system is to reduce the cost of hardware of the main measures. To ensure system averts or cuts down the inside and outside electromagnetism disturbance in industry electromagnetism environment,Should from the suppression noise source, shut off or weaken electronmagetic interference dissemination way, enhancement installment and system aspect and so on antijamming ability takes thesuppression measure. This paper introduces the PLC in industrial control system applications save PLC I / O points with the anti-jamming technology.
Keywords: PLC I / O points reliability anti-jamming technology
