Description
The ProSoft Technology AN-X2-AB-DHRIO is an industrial communication gateway designed to connect modern Ethernet-based automation systems with legacy Allen-Bradley networks. It provides a migration path for facilities that need to maintain existing DH+ or Remote I/O devices while integrating them into EtherNet/IP architectures.
The ProSoft Technology AN-X2-AB-DHRIO allows PLC processors, HMIs, SCADA systems, and industrial computers to exchange data with legacy Allen-Bradley equipment through Ethernet communication. The module handles protocol conversion internally, reducing the need for replacement of existing field hardware.
The ProSoft Technology AN-X2-AB-DHRIO is commonly used in modernization projects involving Allen-Bradley PLC-5, SLC, and other legacy systems. Engineers should verify network topology, node addressing, communication speed settings, and required data mapping before installation.

Product Introduction
ProSoft Technology AN-X2-AB-DHRIO Product Introduction
ProSoft Technology AN-X2-AB-DHRIO is an industrial communication gateway designed to bridge Ethernet-based automation systems with legacy Allen-Bradley Data Highway Plus and Remote I/O networks. It provides a practical solution for plants that require continued operation of existing PLC hardware while adding Ethernet connectivity for supervisory and control applications.
The ProSoft Technology AN-X2-AB-DHRIO operates as a protocol conversion interface between EtherNet/IP networks and older Allen-Bradley communication architectures. It allows modern controllers, HMIs, and software platforms to access data from legacy PLC systems without requiring immediate replacement of field-installed equipment.
The ProSoft Technology AN-X2-AB-DHRIO is frequently applied during PLC migration projects where existing DH+ networks contain valuable installed hardware and proven control logic. Instead of replacing an entire automation system, engineers can use communication gateways to gradually transition equipment toward Ethernet-based architectures.
The module supports industrial environments where communication reliability and compatibility are critical. Proper commissioning requires attention to DH+ node addresses, baud rate settings, Remote I/O configuration, Ethernet parameters, and PLC messaging requirements.
