About the SLC 500 EtherNet/IP Adapter
Overview This chapter provides an introduction to the features and functionalities of the
1747-AENTR SLC 500 EtherNet/IP Adapter. It includes the following sections.
Module Description The 1747-AENTR Adapter enables CompactLogix and ControlLogix
processors to control SLC I/O modules. It is primarily designed to enable
migration of existing SLC controlled systems to Logix-based systems.
The adapter mainly acts as a gateway between the SLC backplane and
EtherNet/IP and typically replaces an SLC controller in the 1746 rack. On
remote SLC racks, it replaces the 1747-ASB module or the ControlNet adapters
1747-ACN15 and 1747-ACNR15.
Control of the backplane I/O is accomplished with a CompactLogix or
ControlLogix controller communicating through an EtherNet/IP router in the
Logix backplane, across EtherNet/IP, and into the 1747-AENTR gateway.
As a gateway between the SLC backplane and EtherNet/IP, the 1747-AENTR
module is a CIP server (for both Explicit Messaging and I/O) on the Ethernet
port, and an SLC host on the 1746 backplane.
