ProSoft PLX31-EIP-SIE Industrial Ethernet Gateway

The ProSoft PLX31-EIP-SIE, also cataloged as the PLX31-EIP-SIE Industrial Gateway, operates as a dedicated hardware component for protocol translation between EtherNet/IP networks and Siemens S7 messaging environments within industrial control architectures. Hardware Specifications Parameter Specification Model PLX31-EIP-SIE Brand ProSoft Technology Origin USA Weight 0.32 kg Dimensions 13.67 x 5.05 x 11.13 cm (5.38 x 1.99 x 4.38 in) Operating Temp -25 to +70 deg C (-13 to +158 deg F) Power Consumption 24 VDC nominal @ 300 mA (10 to 36 VDC @ 600 mA max) Ethernet Ports (2) 10/100 Base-T RJ45 connectors EtherNet/IP Connections Up to 16 Explicit Messaging Connections; Class 1 I/O Siemens Protocol S7 Messaging (Client/Server) Target Siemens Controllers S7-200, S7-300, S7-400, S7-1200, S7-1500 Mounting Standard 35 mm DIN Rail Protocol Conversion Latencies & Isolation The module provides full protocol conversion latencies optimization across isolated subnets via two discrete physical Ethernet interfaces. Deterministic data mapping minimizes memory block processing overhead between the EtherNet/IP Class 1/Class 3 driver buffers and the Siemens S7 client/server driver stacks. Built-in port-to-port galvanic isolation prevents ground loop propagation across segmented plant networks while maintaining steady packet delivery without interconnecting IP subnets. Frequently Asked Questions Q: Does the gateway support seamless recovery if hardware replacement is required? A: Yes. Configuration state and data maps store directly on the local SD card slot, allowing zero-PC hardware restoration during module swapping. Q: Can both Ethernet ports operate on different IP subnet masks? A: Yes. The two physical RJ45 Ethernet ports function independently, allowing routing-free data transfer between distinct subnets without bridging network traffic. Field Installation Guidelines Ensure standard 35 mm DIN rail grounding via low-impedance metallic connections. Maintain minimum 50 mm clearance above and below the module enclosure to allow adequate thermal convection inside high-density enclosures. Drain wire shielding from shielded Twisted Pair (STP) Cat 5e/Cat 6 Ethernet cables must terminate directly to cabinet earth to prevent high-frequency noise from corrupting high-speed packet transfer.
