2.2 Specification comparison of CPU
The following table gives an overview about the characteristics of each CPU. Chapter 4
describes the detailed performance.
2.2.1 Basic model QCPU Q00JCPU, Q00CPU, Q01CPU and Q02CPU
The Q00CPU, Q01CPU and Q02CPU can be used in a multi-CPU system from version B on.
Combinations of Q00CPU and Q01CPU are only possible with Motion Controller CPUs and Q-
PC. These CPUs can’t be operated in one system together with other PLC CPU modules.
Refer to section 4.6 for checking the function version of the CPU module.

One of the following memory cards can be installed for a Q02CPU:
RAM: Q02MEM-1MBS (1 MB) or Q02MEM-2MBS (2 MB)
Flash card: Q02MEM-2MBF (2 MB) or Q02MEM-4MBF (4 MB)
ATA card: Q02MEM-8MBA (8 MB), Q02MEM-16MBA (16 MB) and Q02MEM-32MBA (32 MB)
