33、FT1 OVERVIEW 1 OVERVIEW This manual describes the operations of editing the function block (hereafter abbreviated to the FB) of the GX Developer Version 7 software package (hereafter abbreviated to GX Developer). For the explanation of the functions other than the FB, refer to the corresponding manu
34、als given in the “Related Manuals“. 1.1 What Is Function Block (FB)? The FB is a function designed to convert a ladder block, which is used in a sequence program repeatedly, into a component (FB) to utilize it in the sequence program. This not only increases the efficiency of program development but
35、 also reduces programming mistakes to improve program quality. FBDefinition of FBDefinition of FB definition program and FB variablesFB variablesFB definition programUtilization of FBPasting of FB to sequence program Creation of sequence programCompileDebuggingWrite to PLC 11: GX Developer performs
36、write to PLC to write the compiled sequence program to the PLC CPU. When writing the program to a PLC with “Label program (ST, FB, Structure) “ selected, the FB can be restored using “Read from PLC“. 1 1 - 2 1 - 2 MELSOFT1 OVERVIEW 1.2 Features The FB has the following features. (1) Conversion of pr
37、ogram into component Displaying a standard program as a single block improves the reuse and readability of the program, facilitating editing and debugging. This ensures ease of configuring a large-scale program. (2) Uniform program quality Reusing the components of a standard program provides unifor
38、m program quality, which is independent of the technological level of a program developer. It also prevents programming mistakes during utilization. (3) Editing function of high operability The FB can be utilized easily in a sequence program by drag and drop operation. 1.3 Layouts and Names of Windo
