Compatible Replacement & Equivalent Models
When the 1747-AENTR is unavailable or end-of-life, the following models are commonly evaluated as replacements or functional equivalents. Always verify compatibility with your specific SLC 500 chassis revision and firmware version before substitution.
| Model | Manufacturer | Protocol | Notes |
|---|---|---|---|
| 1747-AENTR (this unit) | Allen-Bradley | EtherNet/IP | Original OEM — direct fit |
| 1747-AENTR/B | Allen-Bradley | EtherNet/IP | Revised firmware version; backward compatible |
| 1747-AENTR/A | Allen-Bradley | EtherNet/IP | Earlier revision; check firmware compatibility |
| 1747-SN | Allen-Bradley | Remote I/O | Legacy RIO adapter; not EtherNet/IP — protocol migration required |
| ProSoft MVI56E-MNET | ProSoft Technology | Modbus TCP / EtherNet/IP gateway | Third-party gateway option for protocol bridging |
| Anybus X-gateway AB7007 | HMS Networks | EtherNet/IP ↔ PROFIBUS | For cross-protocol migration projects |
Note: Third-party equivalents may require additional configuration. Konmask recommends OEM replacements for safety-critical applications.

Selection Guide
Use the following criteria to determine whether the 1747-AENTR is the right module for your application:
| Requirement | Recommended Choice |
|---|---|
| Direct OEM replacement for existing 1747-AENTR | ✅ 1747-AENTR (same or higher revision) |
| Need EtherNet/IP on SLC 500 chassis | ✅ 1747-AENTR |
| Migrating from Remote I/O (RIO) to EtherNet/IP | ✅ 1747-AENTR (replaces 1747-SN) |
| Bridging SLC 500 to PROFIBUS or DeviceNet | ⚠️ Consider ProSoft or Anybus gateway |
| Full system migration away from SLC 500 | ⚠️ Evaluate CompactLogix 5380 platform |
| Budget-constrained retrofit with protocol flexibility | ⚠️ Third-party gateway — consult Konmask engineering |

Replacement & Compatibility FAQ
Q: Is the 1747-AENTR/B a direct drop-in replacement for the 1747-AENTR/A?
A: Yes, in most cases. The /B revision includes firmware improvements and is backward compatible with /A installations. Verify your RSLogix 500 version supports the /B revision EDS file.
Q: Can I use the 1747-AENTR with a SLC 5/03 processor?
A: The 1747-AENTR is primarily designed for SLC 5/05 processors with native Ethernet capability. For SLC 5/03 and 5/04, the adapter functions as a remote I/O chassis adapter — confirm your network architecture with Rockwell Automation documentation.
Q: What is the difference between 1747-AENTR and 1747-AENT?
A: The 1747-AENTR features an embedded dual-port switch enabling ring topology (DLR), while the 1747-AENT has a single RJ-45 port. The AENTR is the preferred choice for new installations requiring network redundancy.
Q: Can I connect this module to a ControlLogix system?
A: Yes. The 1747-AENTR allows a ControlLogix controller to communicate with SLC 500 I/O via EtherNet/IP MSG instructions, enabling hybrid architectures during phased migration projects.
Q: Do you provide a certificate of conformance or test report?
A: Yes. Documentation packages including CoC, inspection reports, and where available, original manufacturer test data, can be provided upon request.
