Subroutine
Label
SBL
When CALL/FCALL/ECALL/EFCALL instruction
is executed, it jumps to subroutines with the
same label number and executes the
subroutines. Use RET instruction to return to
the address of the main program and execute
the program.
"P.3-109"
Subroutine
Return
RET "P.3-109"
Local
Subroutine
Call
CALL
When the trigger (execution condition) is ON:
subroutine is executed.
When the trigger (execution condition) is OFF:
subroutine is not executed.
Holds the output from within subroutines.
"P.3-111"
Output OFF
Type Local
Subroutine
Call
FCALL
When the trigger (execution condition) is ON:
subroutine is executed.
When the trigger (execution condition) is OFF:
subroutine is not executed.
However, the output from within subroutines is
cleared.
"P.3-111"
Subroutine
Call (with PB
number
Specification)
ECALL
For subroutines in the PBn program block:
When the trigger (execution condition) is ON:
jumps to subroutine.
When the trigger (execution condition) is OFF:
subroutine is not executed.
"P.3-113"
Output OFF

EFCALL
For subroutines in the PBn program block:
When the trigger (execution condition) is ON:
jumps to subroutine.
When the trigger (execution condition) is OFF:
subroutine is not executed.
However, the output from within subroutines is
cleared.
