General Information

Core Description

The IC695CPE305 is a high-performance PACSystems RX3i central processing unit powered by a 1.1GHz microprocessor. Fully compatible with the dual PCI/Serial universal backplane, this unit works seamlessly with an optional Energy Pack to deliver battery-less memory retention, embedded programming connectivity, and rapid 0.072 ms Boolean instruction execution without standard upkeep overhead.

Specific Application

• Executing high-speed real-time control loops for intricate material handling setups, high-precision industrial machinery, and multifaceted factory processing lines.
• Managing critical operational safety configurations where traditional hardware batteries must be replaced by a capacitor-based system to prevent volatile data corruption.
• Developing space-optimized standalone distributed automation networks using multi-language logic routines including Ladder Diagram, C, Structured Text, and Function Block Diagram.

Ordering Information

System Compatibility

Backplane Formats: Operates strictly on a rack-mounted backplane utilizing the high-speed VME64 Standard format.

Legacy Module Reuse: Natively supports legacy Series 90-70 discrete and analog I/O cards, communication modules, and compatible VME field modules.

Programming Tools: Programmed and configured over network links via Proficy Machine Edition Logic Developer PLC software.

Alternative Models & Functional Differences

IC698CPE010 (This Module): Houses a 300MHz Celeron microprocessor and delivers a typical execution speed of 0.33ms per 1000 Boolean contacts or coils.

IC698CPE020 (Higher-Tier Alternative): Upgrades the internal architecture to a faster 700MHz Pentium III microprocessor, accelerating Boolean processing down to 0.14ms per 1000 contacts while requiring a dedicated rack fan tray for cooling.

Legacy Series 90-70 CPUs: Legacy main racks cannot house the newer PACSystems modules, as the IC698CPE010 does not operate inside older Series 90-70 chassis infrastructure.

Installation & Troubleshooting FAQ

Q1: What unique hardware steps occur when booting the module with a fully discharged Energy Pack?

A: When power is applied to a rack with a fully discharged or brand-new Energy Pack, the system requires a few seconds to reach operating voltage. During this initialization window, the CPU green STATUS LED blinks continuously.

Q2: Why must the embedded USB type A port be restricted from permanent equipment installation?

A: The universal serial bus interface is designed exclusively for temporary background file movement or loading applications via a removable data storage device. It is structurally unsuited for permanent connection hooks, and must never be plugged in while working within an active hazardous plant zone.

Q3: How can serial communications with the programmer be recovered if both serial ports have been rendered inaccessible by software configurations?

A: You can break the communication lock by removing the external Energy Pack entirely and performing a hardware power cycle. This action executes a complete Clear All sweep that reverts port attributes to factory settings.

Q4: What hidden software parameter oversight causes an operation configuration store to fail on universal analog inputs?

A: When a channel is mapped for a 3-wire RTD hookup, the configuration transfer will immediately fail and log a Loss of Module fault if Lead Resistance Compensation is turned off. To fix it, you must modify the software parameters to enable compensation and power cycle the card.

Q5: What exact logic constraint must be coded when invoking Service Request 57 logic writes to flash?

A: Frequent background flash writes can trip the hardware watchdog timer and trigger a sudden transition into a fatal STOP-HALT sequence. You must restrict your code logic to issue a maximum of one write instruction call per sweep.
