GE IC697BEM711 Bus Expansion Module | Replacement, Equivalent & Selection Guide
The GE IC697BEM711 is a Bus Expansion Module designed for the GE Series 90-70 PLC platform. It enables the connection of remote I/O expansion racks to the main CPU rack via the VMEbus backplane architecture, extending the system’s I/O capacity without compromising scan-cycle integrity. As a critical infrastructure component in large-scale industrial control systems, the IC697BEM711 is widely sought as a replacement or equivalent for aging or obsolete bus expansion hardware.
Selection Background
Industrial buyers frequently search for IC697BEM711 replacements and equivalents when facing end-of-life hardware, emergency breakdowns, or system expansions. Understanding which modules are direct substitutes — and which require configuration changes — is essential to avoiding costly downtime. This guide consolidates that selection intelligence in one place, covering drop-in replacements, functional equivalents, and cross-brand alternatives for the IC697BEM711.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
These modules are hardware-identical or factory-designated successors and can replace IC697BEM711 without software or wiring changes:
- IC697BEM711D / IC697BEM711E — Later firmware revisions of the same model; fully interchangeable in most applications. Verify firmware compatibility with your Logicmaster version.
- IC697BEM711LT — Low-temperature variant; same electrical interface, extended operating range (-20°C to 60°C).
2. Functional Equivalents
These modules perform the same bus expansion function within the Series 90-70 ecosystem but may require rack reconfiguration or cable changes:
- IC697BEM731 — Bus Expansion Receiver (slave side); used in conjunction with a master module. Not a standalone replacement but part of a master/slave pair solution.
- IC697BEM733 — Enhanced bus expansion module with longer cable support; requires IC697CBL730 cable. Suitable when distance between racks exceeds standard IC697BEM711 limits.
3. Cross-Brand Alternatives
For system migrations or when GE Series 90-70 hardware is fully obsolete, the following platforms offer equivalent bus expansion architecture — but require full system re-engineering:
- Siemens ET 200M with IM153-x — Distributed I/O expansion via PROFIBUS; functional substitute in new-build projects.
- Rockwell Allen-Bradley 1756-RIO — Remote I/O adapter for ControlLogix; cross-brand migration path requiring full I/O remapping.
⚠️ Cross-brand alternatives are migration options only. They are not plug-and-play substitutes and require engineering assessment. Contact Konmask for migration feasibility review.

Selection Guide
Answer these three questions to confirm IC697BEM711 is the right module — or to identify the correct replacement:
- What is your existing rack configuration? Confirm rack model (IC697CHS750/782/790) and available slot count. If your rack is a 16-slot model, verify the BEM711 slot assignment does not conflict with CPU or power supply slots. → Contact Konmask with your rack layout for a free compatibility check.
- What cable length is required between racks? IC697BEM711 supports up to 15 m with IC697CBL706. If your installation requires longer runs, IC697BEM733 with IC697CBL730 may be the correct equivalent. → Share your site drawing with Konmask for a cable and module recommendation.
- What firmware revision is your CPU running? Some IC697BEM711 hardware revisions require minimum CPU firmware levels. Mismatched revisions can cause bus initialization failures. → Provide your CPU model and firmware version; Konmask will confirm hardware revision compatibility before shipment.

Replacement & Compatibility FAQ
Q: Can IC697BEM733 directly replace IC697BEM711?
A: IC697BEM733 is a functional equivalent for bus expansion but is not a direct drop-in replacement — it requires a different cable (IC697CBL730) and may need rack configuration updates in Proficy ME. It is the recommended substitute when longer cable runs are needed. Contact Konmask to confirm suitability for your specific installation.
Q: Is IC697BEM711 compatible with all Series 90-70 CPU models?
A: IC697BEM711 is compatible with the majority of Series 90-70 CPUs (IC697CPX928, IC697CPX935, IC697CPU772, etc.), but compatibility depends on CPU firmware revision. Konmask verifies CPU-to-BEM firmware alignment before every shipment to eliminate initialization failures.
Q: What is the best cross-brand substitute if I am migrating away from GE Series 90-70?
A: There is no single plug-and-play equivalent across brands — bus expansion architecture is platform-specific. For migrations to Siemens S7-300/400 or Rockwell ControlLogix, distributed I/O via PROFIBUS DP or EtherNet/IP respectively provides equivalent functionality. Konmask can provide a migration scoping consultation to identify the most cost-effective path.
