APPENDIX 2.2 The program example to execute plural Multiple CPU instruction by the
instructions of one time
This is the program example which executes to the Multiple same Motion CPU at
high speed by one instruction.
In this case, you must take an interlock with "To self CPU high speed interrupt
accept flag from CPU". When an instruction cannot be accepted even if it is
executed, it becomes "No operation".
The program which read the data for 10 points from D0 of the Motion CPU
installing the CPU No.2 to since D100 of the PLC CPU, the data for 10 points
from D200 of the Motion CPU to since D300 of the PLC CPU, and the data for 10
points from D400 of the Motion CPU to since D500 of the PLC CPU by starting of
X0 is shown as an example 1.
At this time, number of multiple CPU dedicated execute instructions at one
command should no exceed the maximum acceptable number of instructions
(Refer to Chapter 5.) of one Motion CPU.
When an maximum acceptable number of instructions is 32, the program which
made not to execute the multiple dedicated instructions when number of the
Multiple CPU dedicated execute instructions exceeds 32 is shown as an example
2.
