Migration Made Simple with the Allen-Bradley 1747-AENTR
Industrial automation evolves, and legacy SLC500 systems often need a bridge to modern Logix platforms. The Allen-Bradley 1747-AENTR serves as that critical gateway, allowing CompactLogix and ControlLogix processors to control SLC I/O modules directly. This module replaces the SLC500 processor in the 1746 rack, transforming distributed I/O stations without replacing existing field wiring.

Industry Applications
Manufacturing facilities with legacy SLC500 racks can modernize their control architecture without replacing I/O modules. The 1747-AENTR enables phased migration: keep existing 1746 I/O while integrating with newer Logix controllers. This reduces downtime and capital expenditure. In material handling and packaging lines, the module supports ring topology for redundant communication paths, improving system availability.
Installation & Setup Guidance
Install the module in the leftmost slot (Slot 0) of any SLC500 chassis. It occupies one slot and draws 470 mA at 5 VDC from the backplane. Before operation, configure the IP address, subnet mask, and optional gateway address via the embedded web interface or BOOTP/DHCP server. Use Category 5 shielded or unshielded twisted-pair cable for Ethernet connections. The module supports star, tree, daisy chain, and ring topologies, giving flexibility for network layout.
Maintenance & Reliability
The 1747-AENTR operates reliably in temperatures from 0 to 60 degrees Celsius. Its open enclosure design requires installation in a clean, dry environment. Inspect Ethernet cable connections periodically for secure mating and physical damage. The module has no user-serviceable internal parts; avoid exposure to condensation (humidity range 5 to 95% without condensation).
Compatibility & Integration
This adapter communicates as a CIP server on the Ethernet port and as an SLC host on the 1746 backplane. It works with CompactLogix and ControlLogix controllers via an Ethernet/IP router. The module replaces the 1747-ASB module or ControlNet adapters (1747-ACN15, 1747-ACNR15) on remote SLC shelves. For standalone SLC500 processors, remove the processor and install the 1747-AENTR in its place.
