5 MOTION DEDICATED PLC INSTRUCTION
[Operation of the self CPU at execution of S(P).SFCS instruction]
(2) Request to start the Motion SFC program of the program No. specified with (n2).
The Motion SFC program can start any task setting of the normal task, event task
and NMI task.
(3) This instruction is always effective regardless of the state of real mode/virtual
mode/mode switching when the operating system software of Motion CPU is
SV22.
(4) S(P).SFCS/S(P).SVST/S(P).CHGA/S(P).CHGV/S(P).CHGT/S(P).DDRD/
S(P).DDWR cannot be executed simultaneously toward the CPU executing
S(P).SFCS instruction.
When the Motion dedicated PLC instruction is started continuously, it is necessary
to execute the next instruction after the complete device of executing instruction
turns on.
