3.1  Memory Configuration

CPU module memory is explained below.

The configuration of CPU module memory is explained below.

The following files are stored in data memory.

Device/label memory has the following areas.

CPU built-in memory

Data memory

The following files are stored in this memory:

• Program files, FB files
• Restored information files
• Parameter files
• Files that contain device comments, etc.

Device/label memory

Data areas for internal devices/labels, etc. are located in this memory.

SD memory card

This is for storing files that contain device comments, etc. and folders and files that are created 
by SD memory card functions.

Device/label memory (standard)

96 Kbytes

R, W, SW, labels, and latch labels can be placed in this memory in variable lengths.
R and W can be backed up in the event of a power interruption only when the optional battery 
is installed. Also, latch label capacity can be increased when the battery is installed.

Device/label memory (fast)

24 Kbytes

Bit devices, T, ST, C, LC, D, Z, LZ, labels, and latch labels can be placed in this memory in 
variable lengths.

For saving device/label memory

25 Kbytes

This memory is for saving latch devices and devices in fast area that require a latch in the 
event of a power interruption.
