*2 Replaced by the value of the function device.
• Up to 16 nesting levels are possible with the CALL(P) instruction. However, this 16 levels is the total number of levels in the
CALL(P), FCALL(P), ECALL(P), EFCALL(P), and XCALL instructions.
• Devices which are turned ON within subroutine programs will be latched even if the subroutine program is not executed.
Devices which are turned ON during the execution of a subroutine program can be turned OFF by the execution of the
FCALL(P) instruction.
