Application-Specific FAQ
Q: Can the 1734-AENT be used with a CompactLogix or ControlLogix controller?
A: Yes. The 1734-AENT is fully compatible with any EtherNet/IP scanner, including CompactLogix (1769-L series), ControlLogix (1756-EN2T/EN3TR), and GuardLogix platforms. Configure via Studio 5000 using the available AOP.
Q: What is the maximum cable distance between the 1734-AENT and the Ethernet switch?
A: Standard IEEE 802.3 limits apply — up to 100 meters (328 ft) per segment using Cat5e or Cat6 copper cable. For longer distances, use fiber media converters.
Q: Does the 1734-AENT support Device Level Ring (DLR) topology?
A: No. The 1734-AENT (single-port) does not support DLR. For ring topology redundancy, specify the 1734-AENTR (dual-port) variant instead.
Q: Is the 1734-AENT compatible with third-party EtherNet/IP scanners (e.g., Siemens, Omron, Mitsubishi)?
A: The 1734-AENT is ODVA-conformance tested and will function with any compliant EtherNet/IP scanner. An EDS file is available from Rockwell Automation’s product compatibility download center (PCDC) for third-party integration.
Q: What firmware revision should I specify for a new installation?
A: Always specify the latest available firmware revision for new installations. Current production units ship with firmware 4.x series. Verify compatibility with your controller firmware using the Rockwell Automation Product Compatibility and Download Center (PCDC) at compatibility.rockwellautomation.com.
Q: Can I hot-swap POINT I/O modules while the 1734-AENT is powered?
A: Yes. POINT I/O modules support removal and insertion under power (RIUP), allowing maintenance without shutting down the entire I/O node — a key advantage in continuous-process industries.
