Mitsubishi Electric MELSEC iQ-R Series Programming Manual page 577

• The EFCALL(P) instruction is used in combination with the ECALL(P) instruction. If the EFCALL(P) instruction is not used
in combination with the ECALL(P) instruction, non-execution processing of the subroutine program is not performed even if
the execution command is turned off, and therefore the output status of each coil instruction is retained.
• When the execution command is turned off, non-execution processing of the subroutine program is performed, enabling the
OUT instruction and PLS instruction (including pulse conversion instructions) to be forcibly turned off.
Ex.
When the EFCALL (P) instruction is used
X0
ECALL "ABC"
EFCALL "ABC"
[ABC.PRG]
