1   OVERVIEW 

 

1.2 Features 

The Motion CPU and Multiple CPU system have the following features. 

 

1.2.1 Features of Motion CPU 

(1)   Q series PLC Multiple CPU system 

(a)   The load of control processing for each CPU can be distributed by 

controlling the complicated servo control with the Motion CPU, and the 
machine control or information control with the PLC CPU, and flexible 
system configuration can be realized. 

 

(b)   The Motion CPU and PLC CPU are selected flexibly, and the Multiple CPU 

system up to 4 CPU modules can be realized. 
The Motion CPU module for the number of axis to be used can be selected.  

Q173CPU(N)        : Up to 32 axes 
Q172CPU(N)        : Up to 8 axes 

 

The PLC CPU module for the program capacity to be used can be selected. 

(One or more PLC CPU is necessary with the Multiple CPU system.) 

Q00CPU                          : 8k steps 
Q01CPU                          : 14k steps 
Q02CPU, Q02HCPU      : 28k steps 
Q06HCPU                       : 60k steps 
Q12HCPU                       : 124k steps 
Q25HCPU                       : 252k steps 

 

(c)   The device data of other CPU can be used as the device data of self CPU 

because the Multiple CPU automatic refresh may do automatically data 
giving and receiving between each CPU of the Multiple CPU system.  

 

(d)   The device data access of the Motion CPU and the Motion SFC program 

start can be executed from PLC CPU by the Motion dedicated PLC 
instruction.  

 
 

(2)   Programming in the Motion SFC programs 

(a)   Since a program intelligible for anyone can be created in flow chart form by 

macking a sequence of machine operation correspond to each operation 
step, maintenance nature improves. 

 
(b)   Since transition conditions are judged with Motion CPU side and positioning 

starts, there is not dispersion in the response time influenced by PLC scan 
time.
