When Qcpu Is Configured In The Multiple Cpu System - Mitsubishi Electric MELSEC IQ-R series Reference Manual

When QCPU is configured in the multiple CPU system

When using C24/E71 in the multiple CPU system of QCPU, refer to the following manual.
 QCPU User's Manual (Multiple CPU System)
Accessing multiple CPU system on connected station (host station)
■When using C24/E71 in the multiple CPU system
Use C24/E71 of which function version is B.
■Accessing multiple CPU system on connected station (host station) from external devices
Control CPU (set with Engineering tool) and non-control CPU of C24/E71 can be accessed.
The usable commands vary depending on the access target QCPU (control CPU, non-control CPU).
Using C24/E71 of which function version is A is also possible. In this case, QCPU No.1 is the control CPU of C24/E71.
Only the control CPU of C24/E71 can be accessed when accessing QCPU on the connected station (host station) from
external devices.
Accessing multiple CPU system on other station
■Use the modules of which function version is B for each station.
Use the modules of which function version is B for each station as shown below.
Type Module
Connected QCPU
station (host
C24/E71 connected to external device
station)
Network module connected to relay station/access station
Relay QCPU
station
Two modules connecting the network between the host station
side and the access station side
Access QCPU
station
Network module connected to relay station
■Accessing multiple CPU system on the other station (access station)
Control CPU and non-control CPU of the network module connected to the relay station can be accessed.
The usable commands vary depending on the access target QCPU (control CPU, non-control CPU).
When accessing other stations from external devices, and any module of which function version is A is included in the above
modules of connected station (host station), relay station, or access station, only the control CPU of network module
connected to the relay station can be accessed. In addition, accessing other station via a module which is controlled by the
same control CPU is available.
The modules which can be accessed other stations via network are as follows.
• CC-Link IE, MELSECNET/H ,MELSECNET/10 Network module
• C24
• E71
