5.2.1 Memory configuration and storable data
This section explains the memories used in the High Performance model QCPU, Process
CPU, Redundant CPU and Universal model QCPU, and the data can be stored in those
memories.
(1) Memory configuration
* 1 : The Universal model QCPU cannot store the error history in the memory card.
* 2 : Can be stored only when the Universal model QCPU is used.
