IC695CRU320CA-EL | PACSystems RX3i 1 GHz CPU Module

Description

Key Technical Specifications

Product Introduction

The IC695CRU320CA-EL is a robust controller within the PACSystems RX3i family, designed to bridge the gap between simple PLCs and high-end PCs. It features a 1 GHz processor capable of executing complex logic and motion control tasks with scan times typically under 1 ms for moderate programs.With 10 MB of user memory, it accommodates large-scale applications that require extensive data logging or complex mathematical functions. The integrated dual-port Ethernet switch simplifies network topology, allowing daisy-chaining of devices without an external switch. The “CA-EL” designation suggests a unit configured for specific international markets or distributor requirements, but it retains the full functional capability of the standard CRU320 architecture.

Installation & Configuration Guide

Preparation (10 min)

• Power down the RX3i rack. Verify 0 V DC at the power supply terminals.
• Ground yourself using an ESD wrist strap. The CPU contains sensitive CMOS components.
• Confirm the backplane slot is free (Slot 1 is recommended for single CPU systems, though RX3i allows flexible slotting).

Removal (5–10 min)

• Disconnect Ethernet and serial cables. Label them clearly (Port 1 vs. Port 2).
• Press the ejector latches on the top and bottom of the module.
• Slide the module out smoothly. Avoid wiggling to prevent bending backplane pins.

Installation (10 min)

• Align the IC695CRU320CA-EL guide rails with the chassis slots.
• Push firmly until the module seats completely against the backplane. Feel for the solid stop.
• Engage the locking levers. They must click into place. If they resist, re-seat the module.

Power-On & Test (10 min)

• Restore power to the rack. Watch the CPU LEDs immediately.
• The OK LED should turn solid green within 15 seconds. Flashing red indicates a firmware mismatch or battery issue.
• Connect a laptop via USB or Ethernet. Launch Proficy Machine Edition.
• Perform a “Verify” operation to check hardware configuration against the loaded project.

Troubleshooting Quick Reference

Dimensions, Mounting & Wiring Notes

• Dimensions: 14.5 cm (H) × 10.2 cm (W) × 16.8 cm (D) – includes handle and connectors.
• Mounting: Slides into RX3i universal backplane slots. Uses integrated locking levers; no screws required.
• Terminal Notes: Ethernet ports use standard RJ45 connectors. Serial port is D-Sub 9-pin male.
• Warning: Do not hot-swap this CPU unless specifically configured and supported by the system architecture (generally not recommended for non-redundant CRU320 setups).

FAQ

Q: What does the “CA-EL” suffix mean?
A: Suffixes like “CA” and “EL” often denote specific distributor configurations, regional certifications (e.g., specific CE variants), or factory-loaded firmware bundles. Functionally, it operates as a standard IC695CRU320. Always verify the specific firmware version on the label before integrating into an existing project.Q: Can I use this to replace an older IC693CPU model from the 90-30 series?
A: No. The physical form factor and backplane pinout differ between the 90-30 series and PACSystems RX3i. You would need to migrate the entire rack and I/O modules.Q: How much memory does this have?
A: The IC695CRU320 series comes with 10 MB of user memory, which is shared between the application logic and data tables.Q: Is this unit new or refurbished?
A: Availability varies. We stock both new surplus and refurbished units. Refurbished items undergo a 24-hour load test and include a 1-year warranty. Check the specific listing status.Q: Does this support redundancy?
A: No, the CRU320 is a single-CPU controller. For redundancy, you would need to look at the RX7i series (e.g., IC698CRE040) or specific high-availability RX3i configurations (if available with other CPU models).Q: What software do I need to program this?
A: You need GE Fanuc Proficy Machine Edition (PME). Ensure your version of PME supports the specific firmware revision loaded on the “CA-EL” unit.

Quality Transparency Strategy (SOP)

1. Incoming Inspection

• Origin Verification: Cross-check serial number format against known Emerson/GE production batches.
• Anti-Counterfeit Check: Inspect holographic labels, font consistency on casing, and PCB build quality.
• Physical Inspection: Look for burnt components, swollen capacitors, or bent backplane pins.
• Suffix Verification: Specifically photograph and log the “CA-EL” suffix to ensure it matches the order and to track regional variants.

2. Live Functional Testing

• Dedicated Test Rack: Loaded into a verified RX3i universal backplane with dummy load modules.
• Power-On Self-Test: Apply 5V DC. Verify “OK” and “RUN” LED sequences.
• Memory Test: Write/Read patterns to the full 10 MB memory space to check for bad sectors.
• Comm Test: Establish connection via both Ethernet ports and USB. Test Modbus TCP and SRTP protocols.
• 24h Load Test: Run a continuous logic scan loop for 24 hours to detect thermal instability.
• Test Report Generated: Document firmware version, MAC address, and test results.

3. Electrical Testing

• Backplane Continuity: Verify continuity on all backplane pins.
• Voltage Drop: Measure 5V DC at the module connector under load. Must be >4.75V.
• Ground Continuity: Verify <0.1 Ω resistance from ground terminal to chassis.

4. Firmware/Revision Verification

• Record Revision: Photograph and log the specific hardware revision and “CA-EL” marking.
• Firmware Version: Read and document the installed firmware version via software.
• Visual Record: Photo record of internal PCB condition (if opened for cleaning) and connector pins.

5. Final QC & Packaging

• QC Signature: Technician signs off on load test and memory verification.
• Anti-static Sealed: Unit placed in ESD shielding bag.
• Bubble Wrap + Carton: Double-boxed with 2-inch foam padding.
• QC Passed Label: Affixed with date, technician ID, and firmware version.
• Statement: Function verified under test conditions. Specific field compatibility depends on total system load and firmware matching.

Technical Pitfall Guide

• Firmware Mismatch:
  • Scenario: An engineer tries to download a project created in PME v9.0 to a CPU running very old firmware (common in “CA-EL” legacy stock).
  • Result: Download fails with “Hardware Mismatch” error.
  • Fix: Always check the firmware version on the unit label or via online connection before purchasing. Update firmware if necessary (requires license and care).
• Battery Failure Leading to Data Loss:
  • Detail: The CRU320 uses volatile RAM backed by a battery. If the battery dies and power is cut, the program is lost.
  • Risk: Unexpected shutdowns after long periods of operation with an old battery.
  • Prevention: Replace the CR2032 battery proactively every 3-5 years or immediately upon seeing the “BAT” LED.
• Ethernet IP Conflicts:
  • Scenario: The CPU comes with a default IP or a previous user’s IP. Connecting it to a live network causes a conflict.
  • Result: Network instability, loss of HMI connection.
  • Fix: Always isolate the CPU on a bench network first to assign a unique IP address before connecting to the plant floor.
• Overloading the Backplane:
  • Scenario: Adding too many high-current I/O modules to a rack powered by a marginal power supply, causing the CPU to reset due to voltage sag.
  • Result: Intermittent faults, “Low Voltage” errors.
  • Rule: Calculate total backplane current draw. Ensure the power supply has 20% headroom.
• Incorrect Slot Usage (Legacy Habits):
  • Detail: While RX3i is flexible, some legacy configurations or specific network adapters expect the CPU in Slot 1.
  • Risk: Confusion during troubleshooting or specific bootloader issues.
  • Best Practice: Install the CPU in Slot 1 unless there is a compelling reason not to, to maintain consistency with standard documentation.
