(2) Data that can be stored in each memory
Table5.1 provides the data that can be stored in each memory.
: Required, : Storable, : Not storable
*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: Any of sequence program, ST program and SFC program data is necessary.
*3: To execute a program stored in the standard ROM, make the setting in the Boot file tab of the PLC parameter dialog box.
*4: Only one file register file can be stored in the standard RAM. ( Section 9.7)
*5: The device comments cannot be read by instructions in a sequence program.
*6: Set the area used by the system. ( Section 5.1.2(2)(b))
*7: Data that stores the label program configuration.
For the label program, refer to the following.
GX Developer Version8 Operating Manual
(3) Memory capacities and necessity of formatting
Table5.2 provides the memory capacities and necessity of formatting of each memory.
Format a memory requiring formatting by GX Developer beforehand.
*1: The standard RAM capacities of the Basic model QCPUs vary depending on their versions. ( Appendix 2.1)
*2: Formatting is unnecessary for the CPU module of function version B or later.
(Formatting the standard RAM from GX Developer to the CPU module of function version B or later displays the error code:
4150
H
on the GX Developer screen.)
When data are written to each memory, the unit of stored file size depends on the target CPU module and memory area.
