Emerson PACSystems™ RX3i Central Processing Unit IC695CPE302

User Features

The PACSystems™ RX3i CPE302 can be used to perform real time control of

machines, processes, and material handling systems. The CPU

communicates with the programmer via the internal Ethernet port or a

serial port. It communicates with I/O and Intelligent Option modules over a

dual PCI/Serial backplane.

▪ Supports an updated OPC stack and encrypting connections

▪ Supports PME’s new GUI management interface for OPC UA configuration

integration (start, stop, restart, clear, and provisioning mode)

▪ Supports the new PAC Security tool available for certificate trust management

of clients and servers

▪ Contains 5 Mbytes of user memory and 5 Mbytes of non-volatile flash user

memory

▪ Supports Battery-less retention of user memory

▪ Configured with an Energy Pack IC695ACC400 to power the CPU long enough

to write user memory to non-volatile storage (NVS) on system power loss

▪ Equipped with configurable data and program memory

▪ Supports programming in Ladder Diagram, Structured Text, Function Block

Diagram, and C

▪ Supports auto-located Symbolic Variables that can use any amount of user

memory

▪ Equipped with reference table sizes to include 32 Kbits for discrete %I and %Q

and up to 32Kwords each for analog %AI and %AQ

▪ Supports most Series 90-30 modules and expansion racks. For supported I/O,

Communications, Motion, and Intelligent modules, refer to the PACSystems

RX3i Hardware and Installation Manual, GFK-2314
