EFCALL(P)

Function

(1) When the EFCALL(P) instruction is executed, the non-execution processing of the 

subroutine program of the pointer designated by Pn is performed.

(a) 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.

File name : Name of the program file to be called (character string)

Pn

: Head pointer number of a subroutine program (Device name)

 to 

: Number of the device to be passed as an argument to a subroutine program 

(bits, BIN 16 bits, BIN 32 bits)
