PACSystems™ RX3i CPE305 Overview

The PACSystems™ RX3i CPE305 is a high-performance CPU designed for real-time control of machines, processes, and material handling systems. It offers flexible communication options with a built-in Ethernet port and serial port for programmer communication, and a dual PCI/Serial backplane for I/O and Intelligent Option module communication.

Specifications

• Memory Retention:

  • Non-volatile storage (NVS) retains data indefinitely without loss of integrity.
  • Upon power restoration, data from NVS is transferred to user memory, and the NVS is cleared.
  • Optional IC695ACC400 Energy Pack available to power the CPU long enough to store user memory contents to NVS during power loss.

• Program Storage:

  • 5 MB of non-volatile flash user memory.

• Power Requirements:

  • +3.3 VDC: 1.0 A
  • +5 VDC: 1.0 A (up to 1.5 A if USB is fully loaded with 0.5 A)
  • +24 VDC:
    • 0.5 A at startup, 0.1 A during runtime (only when Energy Pack is connected).

• Operating Temperature:

  • 0 to 60°C (32°F to 140°F).

• Floating Point:

  • Yes.

• Boolean Execution Speed:

  • Typical: 0.072 ms per 1000 Boolean instructions.

• Time of Day Clock Accuracy:

  • Maximum drift: 2 seconds per day.

• Elapsed Time Clock Accuracy:

  • 0.01% maximum.

• Embedded Serial Communications:

  • RS-232.

• Real-Time Clock Battery:

  • Estimated life: 5 years. Must be replaced every 5 years as part of a regular maintenance schedule.

• Supported Serial Protocols:

• Backplane:

  • Dual backplane bus support: RX3i PCI and 90-30-style serial.
  • PCI compatibility designed to meet PCI 2.2 standard.

• Program Blocks:

  • Up to 512 program blocks.
  • Maximum block size: 128 KB.

• Memory:

  • %I and %Q: 32Kbits for discrete.
  • %AI and %AQ: Configurable up to 32Kwords.
  • %W: Configurable up to maximum available user memory.
