Appendix 4 Functions Added or Changed Due to Version Upgrade
Appendix 4.1 Basic model QCPU Upgrade
APPENDICES
(3) Differences among Basic model QCPU models
*1 : 1 step of the program capacity is 4 bytes.
*2 : 64k bytes for the function version A.
*3 : Memory added to the function version B.
The CPU shared memory is not latched.
The CPU shared memory is cleared when the PLC is powered OFF and then ON or the CPU module is reset.
