EFCALL, EFCALLP
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.
(b) 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:
(2) The EFCALL (P) instruction is used in combination with the ECALL (P) instruction.
The EFCALL (P) can also be used to call a subroutine program that uses a local
pointer from a different program file.
