(5) Communication between CPU modules in the multiple CPU system
The following data transfer can be made between CPU modules in the multiple CPU system.
(a) Data transfer between CPU modules
The following data transfer can be made between CPU modules in the multiple CPU system.
(b) Reading data in another CPU
The QCPU can read data in another CPU with the following instruction when necessary.
• The read instruction from another CPU shared memory
• Multiple CPU shared device (U3En\G
(c) Control direction to the Motion CPU
The QCPU can direct control to the Motion CPU with the following instruction.
• Motion dedicated instruction
(d) Writing/reading device data from the QCPU to the Motion CPU
The QCPU can write/read device data to/from the Motion CPU with the following instructions.
• Multiple CPU transmission dedicated instruction
• Multiple CPU high-speed transmission dedicated instruction
(e) Event issue to the C Controller module or PC CPU module
The QCPU can issue an event to the C Controller module or PC CPU module with the following instruction.
• Multiple CPU transmission dedicated instruction
*1: Refer to the manual of the Motion CPU for instructions dedicated to Motion.
*2: For the multiple CPU transmission dedicated instruction, refer to the manuals of the Motion CPU, C Controller module,
and PC CPU module.
*3: For the multiple CPU high-speed transmission dedicated instruction, refer to the following manuals.
Writing/reading device data to/from the QCPU: QCPU Programming Manual (Common Instructions)
Writing/reading device data to/from the Motion CPU: Manual of the Motion CPU
The Universal model QCPU(except Q00UCPU, Q01UCPU, Q02UCPU) allows executing the motion CPU dedicated instruc-
tion several times in the same scan.
Since the motion CPU dedicated instruction can be executed consecutively to different axis numbers, delay time of servo
startup interval can be shortened.
