POINT
For the High Performance model QCPU whose first 5 digits of serial No. are
"04122" or later, the file size unit has been changed.
Hence, note the following points.
1. Depending on the file capacity, the file executed by the High Performance
model QCPU whose first 5 digits of serial No. are "04122" or later may not be
stored into the High Performance model QCPU whose first 5 digits of serial
No. are "04121" or earlier.
2. Combination of write to PLC and GX Developer
The following table indicates the combination of High Performance model
QCPU and GX Developer versions when a file is read from the High
Performance model QCPU to GX Developer and then written to another High
Performance model QCPU.
Legends : Write to PLC enabled : Restriction on write to PLC
* 1 : Because of different file size units, the file may not be stored into the High Performance model
QCPU depending on the file capacity.
* 2 : Unless the number of allocate memory for online program change is decreased, the file may not
be stored into the High Performance model QCPU depending on the file capacity.
