1.2.1 Features of Motion CPU
The Motion CPU and Multiple CPU system have the following features.
(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.
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.)
(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
(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
