The Allen-Bradley 1747-ACN15, also cataloged as the 1747-ACN15 ControlNet Adapter Module, operates as a dedicated hardware component for ControlNet remote I/O communication between SLC 500 systems and ControlNet network infrastructure.

Model Identification

The 1747-ACN15 is a single-port ControlNet I/O adapter module designed for SLC 500 chassis integration. The module provides ControlNet communication through one BNC connector and one NAP RJ-45 interface while exchanging I/O data through the SLC 500 backplane.

Hardware Specifications

ControlNet Network Communication

The 1747-ACN15 uses ControlNet deterministic network communication for SLC 500 remote I/O applications. The adapter transfers I/O data between ControlNet devices and the SLC 500 backplane through scheduled network communication.

The module supports connection through a BNC network port and a Network Access Port (NAP) RJ-45 interface. Proper network addressing and ControlNet configuration are required before establishing communication with connected devices.

EtherNet/IP and Industrial Control Compatibility

Allen-Bradley SLC 500 communication architectures use defined backplane data exchange paths between processor modules, I/O modules, and communication adapters. The 1747-ACN15 operates as a network interface component, allowing I/O data exchange through ControlNet infrastructure.

Firmware compatibility and network configuration parameters must be verified when integrating the module into existing SLC 500 systems.
