ProSoft PLX32-EIP-SIE Product Description

PLX32-EIP-SIE is a high-performance standalone industrial gateway that enables bidirectional communication between EtherNet/IP and Siemens S7 protocols (S7 Communication), facilitating seamless communication between Rockwell PLCs and the entire series of Siemens S7 PLCs. It features rail-mounted installation, dual network interface isolation, large cache and high throughput.

I. Model Interpretation

PLX32: The new generation of high-end standalone network series

EIP: The side of EtherNet/IP (Rockwell)

SIE: Siemens Industrial Ethernet S7 protocol

II. Hardware Parameters

Power Supply: 10~36VDC, industrial wide-voltage power supply

Network Ports: Dual independent gigabit Ethernet ports, port isolation

Installation: Standard DIN rail installation, universal for control cabinets

Operating Temperature: -25℃ ~ +70℃, wide-temperature industrial grade

Protection: IP20, silent design without fan

Configuration: Built-in Web page configuration, supports configuration import/export, SD card backup

Status Indicators: Power, operation, fault, EIP link, S7 link

III. Protocol Support

1. EtherNet/IP Side

Supports Class1 real-time IO, Class3 explicit messages

Compatible with ControlLogix, CompactLogix, Micro800 series

Can be used as EtherNet/IP master station / slave station, compatible with Rockwell's complete system

Supports EDS file import, direct configuration in Studio5000

2. Siemens S7 Protocol Side

Standard S7 ISO-on-TCP communication

Compatible models: S7-200SMART, S7-1200, S7-1500, S7-300, S7-400

Supports access areas: I zone, Q zone, M storage area, DB data block, L stack area

Supports single-sided reading/writing, bilateral mutual access, no need for both parties to program and interface the underlying protocol

IV. Core Functions

Bidirectional transparent data exchange

EtherNet/IP tag data ↔ Siemens DB blocks / bit storage areas are automatically mapped and directly read/write.

Multi-connection concurrency

The gateway can simultaneously connect multiple Siemens PLCs

Can be accessed by multiple Rockwell PLCs simultaneously

Supports batch reading/writing, continuous register batch acquisition

Data types are automatically adapted

Supports bits, bytes, words, double words, 32-bit floating-point, automatically swap high and low bytes to adapt to industrial control habits.

Fault intelligent handling

Link disconnection automatically reconnects, communication timeout determination, fault marking upload, data freezing and retention.

Zero-depth programming

Only address mapping is required for communication, no need to write S7 protocol messages, no MSG complex logic.

V. Core Advantages

Dual network interface physical isolation, Rockwell network and Siemens network are separated for security

New generation PLX32 platform, faster communication rate, lower latency

Comprehensive support for all series of Siemens PLCs, new and old equipment unified connection

Independent gateway, does not occupy PLC slots, does not occupy CPU resources

Web-based visual configuration, simple debugging, quick online at the site

Industrial wide-temperature strong anti-interference, stable operation in production lines, water treatment, metallurgy, power

VI. Typical Application Scenarios

Cross-brand whole machine communication between Rockwell PLC and Siemens PLC Production Line Transformation: Old Siemens equipment connected to a brand-new EtherNet/IP automated production line

The central control SCADA simultaneously collects data from both Rockwell and Siemens control systems

The workshop connects multiple brand equipment for centralized monitoring and data upload to MES

Imported equipment (Siemens) integrated with the domestic complete line (Rockwell) system

VII. Summary

PLX32-EIP-SIE is the most universal Rockwell ↔ Siemens Ethernet interconnection gateway in industrial sites. Relying on the mature S7 protocol stack + standard EtherNet/IP protocol stack, it enables seamless data communication between the two major industrial control brands. It is the preferred model for project transformation, new equipment integration, and multi-brand networking.
