PROSOFT PLX31-EIP-PND EtherNet/IP to PROFINET Gateway | Replacement, Equivalent & Selection Guide
The PROSOFT PLX31-EIP-PND is an industrial protocol gateway that bridges EtherNet/IP (Allen-Bradley / Rockwell Automation) networks with PROFINET IO (Siemens / IEC 61158) networks. It enables seamless data exchange between PLCs, drives, and field devices across these two dominant industrial Ethernet protocols — without custom programming or middleware.

Selection Guide
Use this guide to confirm the PLX31-EIP-PND is the right model for your application:
- Step 1 — Identify protocol roles: Is your EtherNet/IP controller a Scanner (master)? Is your PROFINET controller an IO Controller (master)? The PLX31-EIP-PND acts as slave on both sides — confirm your PLCs are masters.
- Step 2 — Verify data volume: Does your application require ≤500 words input and ≤500 words output? If more, consider the PLX32-EIP-PND.
- Step 3 — Check mounting: DIN rail installation available? If backplane mounting is preferred, consider PLX51-EIP-PND (ControlLogix chassis).
- Step 4 — Confirm power: 24 VDC available at installation point?
- Step 5 — Environmental rating: Operating within 0–60°C? For harsh environments, consult ProSoft for extended-temp variants.

Replacement & Compatibility FAQ
Q: Can the PLX31-EIP-PND replace an HMS AnyBus X-Gateway AB7007?
A: In most cases yes — both act as EtherNet/IP Adapter and PROFINET IO Device. Verify I/O word count and GSD file compatibility in your PROFINET controller project.
Q: Is the PLX31-EIP-PND compatible with Siemens TIA Portal?
A: Yes. ProSoft provides a GSD file that imports directly into TIA Portal V13 and later for PROFINET IO configuration.
Q: What is the difference between PLX31-EIP-PND and PLX32-EIP-PND?
A: The PLX32 supports Scanner and Controller roles on both sides (master-capable), while the PLX31 is slave-only on both networks. Choose PLX32 if your gateway needs to initiate communication.
Q: Can I use this gateway with CompactLogix 5380?
A: Yes. The PLX31-EIP-PND is compatible with all EtherNet/IP Scanner-capable ControlLogix and CompactLogix platforms including the 5380 series.
Q: Does Konmask.com provide the ProSoft Configuration Builder software?
A: PCB is free to download from ProSoft Technology’s website. We provide the download link and configuration guidance with every order.
