Subroutine program calls
XCALL
• XCALL instruction executes the subroutine program and performs non-execution processing of the subroutine program.
• 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:
• Basic model QCPU: The serial number (first five digits) is "04122" or later.
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)

• Execution of subroutine program: Executes each coil instruction according to ON/OFF status of the condition contacts.
• Non-execution of subroutine program: Performs the same processing for each coil instruction as when the condition contacts are OFF status.
