Being phased out
End of Life · discontinued date February 15, 2027
For now. Rockwell Automation lists the 1747-AENTR as End of Life, with a discontinued date of February 15, 2027. In Rockwell's terms an End of Life product can generally still be ordered until that date; plan spares and the migration now.

What replaces it?
Rockwell's product page for the 1747-AENTR names no one-to-one replacement (Rockwell's replacement category: “Engineering Replacement”). Rockwell's path off the SLC 500 is CompactLogix 5380; its migration guide lists the recommended replacement for each catalog number - check the guide for this one.

Rockwell's migration path
- Rockwell's path off the SLC 500 is CompactLogix 5380 controllers with Compact 5000 I/O. (source)
- Rockwell's SLC 500 Hardware Migration reference manual (publication 1746-RM003) lists a recommended CompactLogix controller for each SLC processor and replacement modules for the 1746 I/O, so it is the place to look up the replacement for one catalog number. (source)
- For the program, Rockwell's SLC to CompactLogix Programming Migration guide (publication 5069-AP001) covers converting an RSLogix 500 project. (source)
- Rockwell's 1492 I/O wiring systems connect the new I/O to the existing field wiring, so the wires can stay where they are. (source)
