10.1 Overview
The multiple CPU high-speed transmission dedicated instruction directs the Universal model
QCPU to write/read device data to/from the Universal model QCPU in another CPU.
The following shows an operation when CPU No.1 writes device data to CPU No.2 with the
multiple CPU high-speed transmission dedicated instruction.
The multiple CPU high-speed transmission dedicated instruction in either host
CPU or another CPU (target CPU module of instruction) is available only for the
following CPU modules.
• Q03UDCPU, Q04UDHCPU, Q06UDHCPU
The first five digits of serial numeber is 10012 or higer.
• Q10UDHCPU, Q13UDHCPU, Q20UDHCPU, Q26UDHCPU
• QnUDE (H) CPU
(1) Parameter setting and system configuration to execute the multiple CPU high-speed
transmission dedicated instruction
The multiple CPU high-speed transmission dedicated instruction can be executed in the
following parameter setting and system configuration.
• CPU No.1 uses QnUD(H)CPU or QnUDE(H)CPU.
• The multiple CPU high speed main base unit (Q3 DB) is used.
• "Use multiple CPU high speed transmission" is selected in the Multiple CPU settings
screen of PLC parameter.
