(b) Program example in which two or more D(P)_DDWR instructions are executed
simultaneously
In the following program, data in the devices ZR0 to ZR999 (1000 points) of the CPU
No. 1 are written to the devices ZR0 to ZR999 of the CPU No.2 using the D_DDWR
instruction.
Two or more instructions to write/read devices between the multiple CPUs can be
executed simultaneously as shown in the following program example.
When executing two or more multiple CPU high speed transmission dedicated
instructions simultaneously to write/read devices, the higher total number of blocks of
the multiple CPU high speed transmission area (send area) shortens the processing
time of the instruction.
