* 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.
* 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 and one local device file can be stored into the standard RAM.
Refer to CHAPTER 2 for the number of storable file register points.
* 6 : Data can be written or read with the following instructions:
• S.FREAD (allows the batch read from a specified file on a memory card)
• S.FWRITE (allows the batch write to a specified file on a memory card)
* 7 : Set the area used by the system. (
* 8 : The drive No. is used to specify the target memory of read/write from the external device, etc.
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.
