* 1 : To execute the program stored in the standard ROM or memory card, boot setting to the program
memory is required in the PLC parameter dialog box. Note that the Universal model QCPU
cannot boot data from the standard ROM to the program memory.(
* 2 : Data can be written by operating from the GX Developer.
Device comments cannot be used in an instruction of a sequence program.
* 3 : The read from a sequence program requires several scans.
* 4 : A sequence program allows the read only.
No data can be written through access from a sequence program.
* 5 : One file register file, one local device file and one sampling trace file can be stored into the
standard RAM.
* 6 : Refer to CHAPTER 2 for the number of storable file register points.
* 7 : Data can be written or read with the following instructions:
• SP.FREAD (allows the batch read from a specified file on a memory card)
• SP.FWRITE (allows the batch write to a specified file on a memory card)
* 8 : Set the area used by the system. (
* 9 : Drive No. is used to specify the target memory to be written/read to/from the external device using
a sequence program or MC protocol.
Since the target memory name is specified on GX Developer, it is not necessary to take into
account the drive No.
* 10 : When the sampling trace file is stored in the standard RAM, check the version of the CPU
module and GX Developer. (
* 11 : Only the Universal models QCPU can be stored in the standard RAM.
* 12 : Store intelligent function module parameters in the same drive with parameters.
Intelligent function module parameters do not become valid when stored to the different drive.
* 13 : The error history data cannot be stored into a memory card for the Universal model QCPU.
