3.2 Function Block (FB) 19 3 Operation overview ■Macro type function blocks The program of a macro type function block is loaded by the calling source program according to the execution flow. At the time of program execution, the loaded program is executed in the same way as the main program. Use a macro type function block when giving higher priority to the processing speed of the program. ■Subroutine type function blocks The program of a subroutine type function block is stored in the FB/FUN file and called by the calling source program when executed. ...

Arrays can be defined by the elementary data types or structures or function blocks. The maximum number of arrays differs depending on the data types. Definition of arrays ■Array elements When an array is defined, the number of elements, or the length of array, must be determined. For the range of the number of elements, refer to the following. Page 27 Maximum number of array elements ■Definition format The following table lists definition format examples ...
