2.1.2 Features Shared by Certain PACSystems CPU Models
â–ª Rx3i CPE302, CPE305, CPE310, CPE330 and CPE400 offer battery-less retention of user memory
when each is connected to its compatible Energy Pack.
â–ª RSTi-EP CPE100/CPE115 offers battery-less retention of user memory with the support of
internal super capacitors.
â–ª All prior RX3i models have battery-backed RAM for user data (program, configuration, register
data, and symbolic variable) storage and clocks.
â–ª Rx3i CPE302, CPE305, CPE310, CPE330 and CPE400 and RSTi-EP CPE100/CPE115 models have
coin battery backup for their real-time clocks (elapsed time clock).
â–ª RX3i CPE302, CPE305, CPE310 and CPE330 models have the ability to upload and download data
from a Removable Data Storage Device (RDSD). This feature is not yet available on RX3i CPE400
and RSTi-EP CPE100/CPE115.
â–ª RX3i CPE302, CPE305, CPE310, CPE330 , CPE400 and RSTi-EP CPE100/CPE115 models support
OPC-UA..
â–ª RX3i CPE302, CPE305, CPE310, CPE330, CPE400 and RSTi-EP CPE100/CPE115 models support
Ethernet Global Data Class 1.
â–ª RX3i CPE302, CPE305, CPE310, CPE330, and CPE400 models support Simple Network Time
Protocol (SNTP) Client, Coordinated Universal Time (UTC), and Daylight Savings Time (DST).
â–ª RX3i CPE330 and CPE400 and RSTi-EP CPE100/CPE115 permit LAN2 to be configured as an
Embedded PROFINET Controller. Refer to Section 2.1.6, Embedded PROFINET Controller.
â–ª RX3i CPE302, CPE305, CPE310, CPE330, and CPE400 models monitor the internal temperature
of the CPU hardware. CPU behavior under these conditions is documented in Section 2.1.9.
For a comparative review of CPU features, refer to RX3i CPU Features and Specifications, RX7i CPU
Features and Specifications and RSTi-EP CPU Features and Specifications. Note that each specific feature
may require a corresponding firmware version of the CPU firmware.
