*1: A drive number is used to specify a memory to be written/read by the external device using a sequence program or MC protocol.
Since the memory name is used to specify the target memory by GX Developer, the drive number needs not to be considered.
*2: Store the intelligent function module parameters in the same drive with the parameters.
When they are stored in different drives, the intelligent function module parameters do not become valid.
*3: A program stored in the standard ROM cannot be executed.
Store the program to the program memory before execution.
*4: To execute a program stored in the memory card, make the setting in the Boot file tab of the PLC parameter dialog box.
*5: The device comments cannot be read by instructions in a sequence program.
*6: Reading from a sequence program requires several scans.
*7: Only each one of file register, one local device, and/or sampling trace file can be stored in the standard RAM.
*8: For the number of storable file register points, refer to Section 9.7.
*9: A sequence program allows reading only. No data can be written from the sequence program.
*10: Data can be written or read with the following instructions.
•
SP.FREAD (batch-reads data from the specified file in the memory card.)
•
SP.FWRITE (batch-writes data to the specified file in the memory card.)
*11: Set an area used by the system. (
