CHAPTER2 PERFORMANCE SPECIFICATION
The table below shows the performance specifications of the CPU module.
2.1 Basic 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.
Section 5.4.4
*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. ( Appendix 4.1)
*4 : The CPU shared memory is not latched.
( QCPU User's Manual (Multiple CPU System)
The CPU shared memory is cleared by turning on the PLC or resetting the CPU module.
