(2) Multiple CPU high-speed transmission dedicated instruction
The Universal model QCPU can write/read device data to/from the Q172DCPU and Q173DCPU with the multiple
CPU high-speed transmission dedicated instruction shown on Table4.16.
Table4.16 List of multiple CPU high-speed transmission dedicated instructions
Instruction
name
D.DDWR Writes host CPU device data into other CPU
DP.DDWR devices.
D.DDRD Reads other CPU device data into the host
DP.DDRD CPU devices.
D.GINT Requests start up of other CPU interrupt
DP.GINT programs.
One QCPU can concurrently issue up to 32 instructions of "Instructions dedicated to Motion CPU" and "Multiple CPU
transmission dedicated instructions (except for S(P).GINT)".
Note that multiple instructions are executed in order starting from the first instruction.
When 33 or more incomplete instructions are identified, an "OPERATION ERROR (error code: 4107)" occurs.
Remark
• For details and availability of the multiple CPU transmission dedicated
instruction, refer to the manual of the Motion CPU.
• The C Controller module has the function which writes/reads device data to/
from the Motion CPU.
For details, refer to the manual of the C Controller module.
