Subroutine output OFF calls between program files
EFCALL(P)
• When the EFCALL(P) instruction is executed, the non-execution processing of the subroutine program of the pointer
designated by Pn is performed.
• The EFCALL (P) can also be used to call a subroutine program that uses a local pointer from a different program file.
File name: Name of the program file to be called (character string)
Pn: Head pointer number of a subroutine program (Device name)
(S1) to (S5): Number of the device to be passed as an argument to a subroutine program (bits, BIN 16 bits, BIN 32 bits)

• Non-execution processing is identical to the processing that is conducted when the condition contacts for the individual coil instructions are in the OFF state.
• The operation results for the individual coil instructions following non-execution processing will be as follows, regardless of the ON/OFF status of the individual
contacts:
