Product Introduction

is the modern flagship single-slot PACSystems RX3i CPU, designed for new projects and legacy system migration.The biggest advantage: integrated triple gigabit Ethernet, eliminating the requirement for separate IC695ETM001 communication modules. Two independent LAN domains enable network segmentation (control network / HMI/SCADA network).

LAN2’s built-in switch supports simple daisy-chain of PLCs without external switches. The USB RDSD port allows offline program backup/restore without programming software connection.

Key migration capability: Built-in compatibility mode, can emulate IC695CPU315 / CPU320 / CRU320, enabling direct hardware upgrade for existing Series 90-30 migrated RX3i racks.Supports hot standby redundant configurations for high-availability process applications, and embedded PROFINET controller functionality.

Critical Distinction

1. : Single-slot, onboard Gigabit Ethernet, modern CPU.
2. IC695CPU315 / CPU320: Dual-slot, NO onboard Ethernet, requires IC695ETM001.Mechanically not direct plug-in; rack slot layout must be modified when upgrading legacy dual-slot CPUs to CPE330.

 

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking. Inspect backplane gold pins for bending/corrosion; inspect RJ45 ports, USB port and housing integrity.
2. Live Testing: Mount onto validated RX3i baseplate. Load user control program, verify cyclic logic execution, test all Ethernet ports, validate USB RDSD upload/download function, run continuous 24-hour stability test.
3. Electrical Testing: Monitor backplane 3.3V/5V rail stability. Insulation resistance ≥10MΩ between Ethernet circuits and chassis protective ground.
4. Firmware Record: Document CPU firmware revision; photograph front panel switch position before clearing resident program and retentive data.
5. Final QC & Packaging: Place module inside anti-static shielding. Attach dated QC test tag confirming logic execution, Ethernet communication and RDSD function validation prior to shipment.

 

Installation Pitfalls & Guide

❗ No Hot Swap Support: The CPU module cannot be hot swapped. Full rack power shutdown required before removal. Standard I/O modules support hot swap on certified baseplates.❗ Single Slot Layout Change Warning: When replacing legacy dual-slot CPU315/CPU320 with CPE330, free up one slot; re-plan slot layout for other modules.❗ Dual LAN Network Design: LAN1 and LAN2 are independent IP domains. Do not connect both to the same physical network to avoid duplicate EGD multicast consumption.❗ Compatibility Mode Rules: Firmware V8.70+ supports emulation of CPU315//CRU320 via hardware button; older firmware limited to emulation.❗ RDSD USB Limitation: Only dedicated industrial USB flash drives supported; generic consumer flash drives may cause unstable operation.❗ Battery Maintenance: Without IC695ACC302 battery, retentive variables and RTC will be lost after power cycle.❗ ESD Risk: Static discharge damages Ethernet PHY transceivers, leading to random link flapping and communication faults.

Replacement Guide

1. Pre-install: Lockout-tagout rack power; back up complete PLC project. Photograph slot layout, Ethernet wiring and battery connection.
2. Removal: Disconnect all Ethernet/USB cables; unlatch CPU and slide straight out without twisting backplane pins.
3. Install: Seat new into target single slot, reconnect Ethernet and USB cables, confirm battery installation.
4. Power-on Test: Restore rack power; confirm CPU OK / RUN LED status, download project, verify all Ethernet communication channels and I/O scanning.

 

FAQ

Q: Does support hot swapping?A: No. The CPU module itself cannot be hot swapped. Standard RX3i I/O modules support hot swap on hot-swap rated backplates.

Q: What is the major difference between and IC695CPU320?A:

• : Single-slot, built-in triple Gigabit Ethernet, USB RDSD, newer processor.
• IC695CPU320: Dual-slot, no onboard Ethernet, requires IC695ETM001.They are not physically interchangeable without rack layout adjustment.

Q: Can run hot standby redundancy?A: Yes, supports hot standby redundant architecture, compatible with EGD and Genius I/O redundancy schemes.

Q: Does it need separate IC695ETM001 Ethernet module?A: No. All Ethernet ports are embedded onboard. Additional ETM modules can be added only for extra communication ports.

Q: Can I run existing programs directly on CPE330?A: Yes. Enable compatibility mode on the CPE330, existing projects can be downloaded without full conversion (PME version dependent).

Q: Can this CPU connect Series 90-30 I/O modules?A: Yes, via IC695LRE001 serial expansion transceiver on remote racks. IC693 modules cannot be plugged directly into RX3i main backplane.

Q: Are the two RJ45 ports on LAN2 separate IP addresses?A: No. LAN2 uses an internal switch; both ports share one single IP. LAN1 is fully independent with separate IP address.
