32 MEMORY SPECIFICATIONS
This chapter describes the memory specifications of the Safety CPU. Information not described in this chapter is same as that
of the standard CPU. ( Page 92 MEMORY CONFIGURATION OF THE CPU MODULE)
32.1 Memory Configuration
Specifications of the device/label memory differ from the standard CPU in the memory configuration of the Safety CPU.
Device/label memory
In addition to standard devices and standard labels, the data such as safety devices and safety labels are allocated to each
data area of the device/label memory.
The safety device area, safety label area, safety local device area, and standard/safety shared label area are allocated
between the standard device area and standard label area. The capacities for each area can be changed in "Device/Label
Memory Area Setting" of the engineering tool. ( Page 544 Device/Label Memory Area Setting)
Data to be allocated
The following table lists the data allocated to each area.
Area Application
Standard device area Standard user devices
Safety device/label area Safety device area Safety user devices
