GE IC697CMM742-FF Ethernet Interface | Series 90-70 PLC Platform
Engineering Background
The IC697CMM742-FF is a high-performance Ethernet communication module designed for GE Fanuc’s Series 90-70 programmable logic controller platform — one of the most widely deployed rack-based PLC architectures in heavy industrial automation. Engineered to bridge legacy control infrastructure with modern Ethernet-based supervisory and SCADA networks, this module enables deterministic, high-throughput data exchange without requiring a full system migration.
Product Positioning
Targeted at process engineers and control system integrators managing brownfield installations, the IC697CMM742-FF delivers enterprise-grade Ethernet connectivity within the proven Series 90-70 backplane ecosystem. It is the preferred choice for facilities requiring long-term parts availability, backward compatibility, and certified interoperability with GE Proficy and third-party HMI/SCADA platforms.

System Architecture & Signal Flow
The IC697CMM742-FF occupies a single slot in the Series 90-70 rack and communicates directly with the CPU module via the VME backplane at full backplane bandwidth. On the network side, the module presents a standard RJ-45 Ethernet port supporting 10/100 Mbps auto-negotiation. Data flow is as follows:
- Inbound (SCADA → PLC): Ethernet frames received by the module are decoded via SRTP or Modbus TCP, translated to backplane register/coil addresses, and written to the CPU’s %R, %AI, %AQ, or %Q memory tables in real time.
- Outbound (PLC → SCADA): CPU memory table data is polled by the module on each scan cycle and transmitted as Ethernet frames to configured SCADA/HMI clients upon request or on change-of-state.
- Isolation: Electrical isolation between the Ethernet physical layer and the backplane bus protects the CPU from network-side transients.
Sourcing & Quality Verification
- Source: Procured from authorized distributors, certified MRO suppliers, and decommissioned industrial facilities with documented maintenance histories.
- Inspection Protocol: Each unit undergoes visual inspection (PCB, connectors, label integrity), functional power-on verification, and backplane communication test prior to listing.
- Condition Grading: Units are graded as New (factory-sealed), Refurbished (tested, cleaned, re-labeled), or Used-Tested (functional, cosmetic wear acceptable) — condition specified at checkout.
- Counterfeit Mitigation: Firmware version, board revision, and GE Fanuc serial number format are cross-referenced against known-good reference units.
- Warranty: 90-day functional warranty covering communication failure and backplane interface defects under normal operating conditions.

Technical FAQ
Q: Is the IC697CMM742-FF compatible with all Series 90-70 CPU models?
A: Yes. The module is compatible with all standard Series 90-70 CPUs (IC697CPU7xx series) and supports both single and redundant CPU configurations when used with appropriate redundancy modules.
Q: Can this module replace an IC697CMM741 or IC697CMM742?
A: The IC697CMM742-FF is a firmware revision of the IC697CMM742 family. Functional compatibility with IC697CMM741 applications is high, but firmware version and configuration file compatibility should be verified in GE Proficy Machine Edition before deployment.
Q: What is the maximum number of Ethernet connections supported?
A: The module supports up to 16 simultaneous SRTP client/server connections and up to 32 Modbus TCP connections, depending on firmware revision.
Q: Does the module support SNMP or web-based diagnostics?
A: Diagnostic access is provided via GE Proficy Machine Edition’s online monitoring tools. Native SNMP or embedded web server functionality is not supported on this module generation.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 1–3 business days of order confirmation. Lead time for sourced units is 5–15 business days depending on availability.
