Bridging Two Worlds: PLX32-EIP-PND – The EtherNet/IP™ to PROFINET® Gateway for Dual Subnets

Introduction

In the era of Industry 4.0 and smart manufacturing, few factories run on a single control network. More often than not, Rockwell Automation's EtherNet/IP and Siemens-dominated PROFINET coexist – but they don't always communicate well. Enter the PLX32-EIP-PND from ProSoft Technology. This standalone, DIN-rail mounted gateway is purpose-built for dual-subnet architectures, offering bi-directional data transfer without the need for complex routing or middleware. Backed by official certifications from both network bodies, it delivers the performance, ease-of-use, and ruggedness that modern production lines demand.

1. Product Overview: Dual-Network, Single Solution

The PLX32-EIP-PND features two independent Ethernet ports, each on a separate subnet – a critical design for keeping network traffic isolated while enabling seamless data exchange. Key hardware highlights:

• Onboard SD card slot (card optional) enables configuration backup, cloning, and disaster recovery in seconds.
• Conformal coating option available for use in humid, dusty, or chemically aggressive environments.

2. Key Advantages: Certified, Capable, and Code-Free

2.1 Dual Certification Means Peace of Mind

• ODVA Approved for EtherNet/IP and PROFINET v2 Certified (Class A compliance).
• Thoroughly field-tested with multiple PROFINET controllers from leading vendors (Siemens, Phoenix Contact, etc.).

2.2 Massive Data Handling Capacity

• Supports up to 10,000 16-bit registers for large-scale data exchange – ideal for recipes, machine diagnostics, or batch traceability.
• 8 Class 1 I/O connections, each with up to 496 bytes IN/OUT and a minimum RPI of 5 ms, meeting demanding real-time control requirements.

2.3 Native Integration, No Ladder Logic Required

• Built-in EDS and AOP files enable one-click integration into Studio 5000 and RSLogix 5000 – the gateway appears as a native module.
• Using EtherNet/IP I/O connections, data mapping is configured without writing a single rung of ladder logic, saving significant engineering time.

4. Typical Use Cases

Automotive assembly: PROFINET robots on the body shop, EtherNet/IP HMIs and drives on the final line – the gateway synchronizes data across both.

Material handling: Rockwell PLCs managing sorters, while PROFINET servos control stacker cranes – all coordinated through one gateway.

Water/wastewater treatment: Mixed architectures consolidated into a single SCADA view with reliable protocol translation.

5. Operations & Security: Built for Real-World Demands

Remote diagnostics allow viewing and troubleshooting both networks from a central location, reducing mean time to repair (MTTR).

Secure configuration lock via a physical module switch (firmware v1.04 and above) prevents unauthorized changes – a simple yet effective cybersecurity measure.

Final Thoughts

The PLX32-EIP-PND is more than a protocol converter – it's a strategic enabler for heterogeneous automation environments. With dual certifications, high data throughput, and a rugged design, it offers system integrators and end users a reliable, cost-effective path to true interoperability.

Whether you're upgrading an existing line or building a new greenfield facility, this gateway deserves a spot on your shortlist.
