ProSoft PLX32-EIP-SIE Protocol Gateway

The ProSoft PLX32-EIP-SIE, also cataloged as the PLX32-EIP-SIE Standalone Gateway, operates as a dedicated hardware component for bi-directional protocol conversion between EtherNet/IP and Siemens Industrial Ethernet networks within industrial automation platforms.

Suffix Breakdown & Model Matrix

The base module identifier defines the physical enclosure and internal protocol driver matrix:

• PLX32: ProSoft LineX express physical enclosure platform featuring dual isolated Ethernet interfaces, DIN-rail mount bracket, and SD card configuration slot.
• EIP: Primary interface driver supporting EtherNet/IP explicit/implicit Class 1 messaging (Server/Client).
• SIE: Secondary interface driver executing Siemens Industrial Ethernet S7 messaging protocol over TCP/IP (Server/Client).

Hardware Specifications

Dynamic Protocol Conversion Latency & Subnet Isolation

The dual RJ45 architecture provides galvanic and physical network separation between discrete Ethernet subnets. The module internal processing engine coordinates data transfer between the EtherNet/IP driver and the Siemens Industrial Ethernet driver using an internal 10,000-word register database. Cross-subnet traffic isolation prevents broadcast storm propagation between ControlLogix and S7 networks while maintaining deterministic response latencies across both ports.

Frequently Asked Questions

Q: Does replacing a PLX32-EIP-SIE module require a PC to restore configuration on-site?

A: No. The unit features an integrated SD card slot. Moving the SD card from the existing gateway to a replacement unit restores all network configurations, mapping tables, and IP addresses automatically upon power-up.

Q: Can both Ethernet ports be assigned to the same subnet for pass-through switching?

A: No. The two Ethernet ports function as distinct, isolated network interfaces across separate subnets. They must be configured with independent IP addresses to facilitate cross-network mapping between EtherNet/IP and Siemens subnets.

Field Installation Guidelines

Ensure the gateway is secured on a standard 35 mm DIN rail inside an IP54 or better enclosure to protect against environmental contaminants. Connect the protective earth (PE) ground wire directly to the ground screw terminal provided on the chassis using a minimum 14 AWG conductor. Maintain a minimum clearance of 50 mm above and below the device for convection airflow cooling. Ensure signal lines are routed away from high-voltage motor power cables to mitigate high-frequency EMI interference.
