2.3.2 Control Instruction from the PLC CPU to The Motion CPU (Motion dedicated
instructions)
Control can be instructed from the PLC CPU to the Motion CPU using the Motion
dedicated PLC instructions listed in the table below.
Refer to the "Q173HCPU/Q172HCPU Motion controller (SV13/SV22) Programming
Manual (Motion SFC)" or "Q173HCPU/Q172HCPU Motion controller (SV43)
Programming Manual" for the details of each instruction.
(Control may not be instructed from the Motion CPU to another Motion CPU.)

POINT
One PLC CPU can execute a total of up to 32 "Motion dedicated instructions" and
"dedicated instructions excluding the S(P).GINT" simultaneously.
When Motion dedicated instructions and dedicated instructions excluding the
"S(P).GINT" are executed simultaneously, the instructions will be processed in the
order received.
If the command which has not completed processing becomes 33 or more, an
OPERATION ERROR (error code: 4107) will be occurred.
