Communication By Auto Refresh Using Multiple Cpu High Speed Transmission Area - Mitsubishi Electric MELSEC Q Series User Manual

4.1.3 Communication by auto refresh using multiple CPU high speed
transmission area
The following describes the communication by the auto refresh using the multiple CPU high speed transmission area
in the Universal model QCPU.
The communication by the auto refresh using the multiple CPU high speed transmission area can be performed only
when the following conditions are all met.
• The multiple CPU high speed main base unit (Q38DB or Q312DB) is used.
• The Universal model QCPU (except the Q00UCPU, Q01UCPU, Q02UCPU) is used as the CPU No.1.
• At least two modules are used among the Universal model QCPU (except the Q00UCPU, Q01UCPU,
Q02UCPU) and the Motion CPU (Q172DCPU, Q173DCPU).
Communication using the multiple CPU high speed transmission area by auto refresh cannot be made with the CPU
modules except the Universal model QCPU (except the Q00UCPU, Q01UCPU, Q02UCPU) and Motion CPU
(Q172DCPU, Q173DCPU) mounted on the multiple CPU high speed main base unit.
When these modules have been mounted on the multiple CPU high speed main base unit, set 0 to the relevant CPU
by the "point" field in "CPU specific send range" of "Multiple CPU high speed communication area setting".
Set 0 for the CPU modules except the
Universal model QCPU (except the
Q00UCPU, Q01UCPU, Q02UCPU) and
Motion CPU(Q172DCPU, Q173DCPU).
For "Communication by auto refresh using CPU shared memory", refer to Section 4.1.2.
