Remarks
S and R operators are available as standard instructions in the IL"Instruction list" This is a low-level language and resembles assembly language. In FFLD languages they are represented by (S) and (R) coils. In FBD"Function block diagram" A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks language, you can use (S) and (R) coils, but you must prefer RS and SR function blocks. Set and reset operations are not available in ST"Structured text" A high-level language that is block structured and syntactically resembles Pascal language.
ST Language
Not available.
FBD Language
