36、rnational Standard IEC61131-3 that stipulates the logic description system in open controllers.The ST language supports operators, control syntaxes and functions to permit thefollowing descriptions.The main features of the ST language are as described below.(1)description in text formatThe ST langua

37、ge allows the description of alphanumeric characters, comments and labels in text format.(2)Programon the same level as those of the C and other high-level languagesLike the high-level languages such as C, the ST language can describe control with control syntaxes such as conditional sentence-depend
