CALL / Call Subroutine
Outline
This instruction calls and executes a program which should be processed commonly in a sequence program.
This instruction saves the number of program steps, and achieves efficient program design.
For creating a subroutine program, FEND and SRET instructions are required.
A similar processing is available by creating a function block and read it out from the program block.
Refer to the following manual for creating function blocks.
