For a comparative review of CPU features, refer to RX3i 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.
2.1.2

Firmware Storage in Flash Memory

The CPU uses non-volatile flash memory for storing the operating system firmware. This
allows firmware to be updated without disassembling the module or replacing EPROMs.
The operating system firmware is updated by connecting to the CPU with a PC
compatible computer and running the software included with the firmware upgrade kit.
CPU Features & Specifications
Indirect mechanism for upgrading firmware in backplane modules via the CPU.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400 and CPL410 offer battery-less
retention of user memory when each is connected to its compatible Energy Pack.
RSTi-EP CPE100/CPE115 offers battery-less retention of user memory with the
support of internal super capacitors.
All prior RX3i models have battery-backed RAM for user data (program,
configuration, register data, and symbolic variable) storage and clocks.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400, CPL410 and RSTi-EP
CPE100/CPE115 models have coin battery backup for their real-time clocks
(elapsed time clock)
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, CPL410 and RSTi-EP CPE100/CPE115.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400 and CPL410 models support OPC-
UA. This feature is pending on RSTi-EP CPE100/CPE115.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400, CPL410 and RSTi-EP
CPE100/CPE115 models support Ethernet Global Data Class 1.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400 and CPL410 models support
Simple Network Time Protocol (SNTP) Client, Coordinated Universal Time (UTC),
and Daylight Savings Time (DST).
RX3i CPE330, CPE400, CPL410 and RSTi-EP CPE100/CPE115 permit LAN2 to be
configured as an Embedded PROFINET Controller. Refer to Section 2.1.5, Embedded
PROFINET Controller.
RX3i CPE330, CPE400, CPL410 support up to 768 blocks including the _MAIN block
with firmware release 9.70 or later. Note that PME 9.50 SIM 13 or later is also
required for supporting a block count of up to 768.
RX3i CPE302, CPE305, CPE310, CPE330, CPE400 and CPL410 models monitor the
internal temperature of the CPU hardware. CPU behavior under these conditions is
documented in Section 2.1.10.
