AliaThis paper describes the design and implementation of an interface card (IC) with analogue input and digital output, designed for use with small size PLCs, which do not support interface features. The absence of generic I/O interface modules due to the differences in PLCs design and software, validates the importance of such work. The IC costs about one third of … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,442 accessesView PDFCite
