IntroductionThis chapter explains basic items related to programming in FX3U and FX3UC programmable controllers(PLCs).1.1 Programming Language in PLCsThis section explains the features of programming in FX3U and FX3UC PLCs.1.1.1 Types of programming languagesFX3U and FX3UC PLCs support the following three types of programming languages:1. List programmingThis method is the basis of programs.1) FeaturesIn this method, sequence instructions are input in the form of instruction words such as "LD", "AND" and"OUT".This input method is the basis of sequence programs.2) Example of list display2. Circuit programmingIn this method, ladder formats are drawn on the graphic screen.1) FeaturesIn a circuit program, a sequence circuit is drawn on the graphic screen by sequence formats and devicenumbers. Because a sequence circuit is expressed with contact symbols and coil symbols, the contentsof a program can be understood easily.In the circuit display status, the PLC operations can be monitored.2) Example of circuit display3. SFC (STL ) programmingThis input method allows sequence design in accordance with the flow of machine operations.1) FeaturesIn an SFC (sequential function chart) program, sequences can be designed in accordance with the flow ofmachi
