PERFORMANCE SPECIFICATION
2.2 High performance model QCPU
*1
: The unit of the file size stored in the memory area varies depending on the CPU module. For the details, refer to the manual below.
(
*2
: The maximum number of executable sequence steps is as shown below.(Program capacity) - (File header size (default: 34 steps))For
the details, refer to the manual below.
Refer to CHAPTER 5 for details of the program capacity and file.
*3
: The capacity has been increased due to the function upgrade of the CPU module. (
*4
: The CPU shared memory is not latched.
