The Best 1756-DHRIO Replacement & ProSoft Alternative:
ANC-100e Ethernet/IP to DH+ Gateway
A reliable 1756-DHRIO replacement is essential when connecting legacy Data Highway Plus (DH+) networks to modern SCADA architectures. Specifically, Rockwell Automation officially discontinued the 1756-DHRIO module in December 2024, leaving plant engineers searching for a practical upgrade path. Therefore, installing this proven 1756-DHRIO replacement protects critical communication with legacy PLC-5 and SLC 5/04 controllers without requiring full ControlLogix chassis hardware.
In addition, the ANC-100e functions as an economical 1756-DHRIO replacement and ProSoft alternative that delivers seamless Ethernet/IP routing. Moreover, it provides fast commissioning through an intuitive web-based interface. Consequently, system setup takes only minutes, eliminating complex proprietary driver routing.
Why Upgrade to this ProSoft & 1756-DHRIO Alternative?
Integrating legacy Data Highway Plus networks into modern Ethernet architectures is often blocked by discontinued hardware. Therefore, selecting a dedicated 1756-DHRIO replacement solves the major operational hurdles plant engineers face:
- Official OEM Obsolescence: Rockwell Automation officially discontinued the 1756-DHRIO on December 31, 2024. Consequently, plants need a proven hardware replacement to avoid buying unverified surplus equipment.
- ProSoft Supply Chain Delays: Waiting weeks or months for ProSoft AN-X2-AB-DHRIO replacements causes unacceptable downtime.
- High Chassis Costs: Using an Allen-Bradley 1756-DHRIO requires purchasing a full ControlLogix rack, power supply, and Ethernet adapter (1756-ENBT/EN2T). As a result, total costs often exceed $4,000 to $6,000 USD.
- Complex Integration: Legacy routing often involves tedious manual IP configurations and mapping that prolong commissioning times.
ANC-100e vs. ProSoft AN-X2 & 1756-DHRIO Comparison
The ANC-100e provides a high-performance, DIN-rail mountable gateway that serves as an ideal 1756-DHRIO replacement option, bypassing the high costs of ControlLogix chassis setups and ProSoft stock shortages.

Typical Network Architecture: Bridging modern Ethernet SCADA/HMI systems with legacy DH+ nodes via the ANC-100e gateway.
Frequently Asked Questions: Upgrading to the ANC-100e
Is the ANC-100e a suitable replacement for the ProSoft AN-X2-AB-DHRIO?
Absolutely. The ANC-100e is engineered as a highly efficient hardware replacement and alternative for ProSoft gateways. Furthermore, it seamlessly handles Ethernet/IP to Data Highway Plus (DH+) routing, ensuring your PLC-5 and SLC networks communicate smoothly with modern SCADA systems.
Can I use the ANC-100e as a 1756-DHRIO replacement module?
Yes, without a doubt. Deploying this 1756-DHRIO replacement eliminates the need to buy an expensive ControlLogix rack, power supply, and 1756-ENBT card. Consequently, you save thousands of dollars while achieving the exact same Ethernet to DH+ bridging capabilities in a standalone DIN-rail device.
How difficult is the network configuration?
First, the setup process is designed to be completely user-friendly through a simple Web-Based Interface. In addition, it supports Auto Baud Rate detection for DH+ (57.6, 115.2, and 230.4 kbps), which drastically reduces human error and commissioning time during installation.
