Maintaining the legacy GE Fanuc / Emerson PACSystems RX7i IC698CRE020 CPU? Get precise technical specs, redundancy insights, and strategic stocking recommendations.
Version 1: Standard SEO Review Style
In large-scale, high-availability industrial control architectures, a primary processor failure can freeze full-scale production lines instantly if a seamless hot-standby failover loop is not active. The Emerson / GE Fanuc PACSystems RX7i IC698CRE020 is a 700 MHz high-performance, single-slot CPU module engineered specifically for high-availability redundant architectures. Operating on a VME64-compliant backplane, this processing unit features 10 MB of non-volatile flash memory for logic execution and built-in dual Ethernet ports, delivering the processing speed and communication bandwidth required to manage highly complex, time-critical control algorithms.
Technical Specification Snapshot
Before checking a replacement CPU into your active warehouse inventory or initializing a hot-standby swap, verify these precise operating limits:
| Parameter | Specification Value |
| Model Code | IC698CRE020 (Includes variations like IC698CRE020-ED) |
| Product Family | PACSystems RX7i (Originally GE Fanuc, now Emerson) |
| Processor Type | 700 MHz Celeron / High-Performance Controller |
| User Memory | 10 MB Non-Volatile Flash User Memory |
| Boolean Execution Speed | 0.14 ms per 1,000 Boolean contacts/coils |
| Power Requirements | • +5 VDC: 4.5 Amps nominal
• +12 VDC: 0.042 Amps nominal • −12 VDC: 0.008 Amps nominal |
| Integrated Communication | Dual 10/100 Mbps RJ-45 Ethernet Ports + Three Serial Ports |
| Redundancy Support | Native hot-standby CPU redundancy (requires RMX modules) |
| Cooling Requirement | 0 to 60 °C (32 to 140 °F) — Fan kit required for chassis operation |
| Configuration Software | Proficy Machine Edition (PME) |
Sparing & Operational Strategy
Applying a standard industrial ABC inventory framework classifies the IC698CRE020 as a Class A critical asset. As the central processor governing the entire system, its operational availability dictates the uptime of the entire plant. Even in a dual-redundant pairing, operating a single CPU without a local backup strips away your infrastructure’s fault tolerance, leaving your operations vulnerable to a single-point-of-failure shutdown.
Because the legacy PACSystems RX7i series has transitioned completely out of active production, relying on standard distributor networks introduces extreme lead-time volatility. For facilities running critical continuous manufacturing or infrastructure loops, maintain a strict 1:1 on-site safety stock of this processor.
Not Recommended For:
Do not force this processor into low-power PACSystems RX3i or standard Series 90-30 chassis. The electrical pinout and wide physical form factor are designed strictly for the VME64-compatible RX7i backplane structure.
