The ProSoft PLX31-EIP-SIE is a Protocol Gateway that enables seamless communication between EtherNet/IP (CIP) networks and Siemens S7 Industrial Ethernet (S7 IE) networks. It acts as a bi-directional translator, eliminating the need for custom programming to integrate these two widely used industrial protocols.
The PLX31-EIP-SIE is a standalone, rack-mountable gateway designed for industrial automation environments. It connects Rockwell Automation EtherNet/IP devices (e.g., CompactLogix, ControlLogix PLCs) with Siemens S7 controllers (e.g., S7-300, S7-400, S7-1200, S7-1500) over their respective Ethernet-based protocols. The gateway handles all protocol translation, allowing data exchange between the two networks without modifying the logic of the existing PLCs.
- Bi-Directional Protocol Translation: Enables real-time data transfer between EtherNet/IP (as a Scanner/Adapter) and Siemens S7 Industrial Ethernet (as a Client/Server). Supports both cyclic (real-time) and acyclic (configuration/command) data exchange.
- High Data Capacity: Can map up to 4096 bytes of input data and 4096 bytes of output data between the two networks, accommodating large-scale data transfer requirements for complex applications.
- Easy Configuration: Set up via ProSoft Configuration Builder (PCB) software. The intuitive interface allows users to define data maps, configure connection parameters, and monitor network status without low-level programming.
- Robust Diagnostics: Provides detailed diagnostic information (via PCB and module status indicators) for troubleshooting network issues, connection failures, and data transfer errors, minimizing downtime.
- Redundancy Support: Optional support for EtherNet/IP device-level ring (DLR) redundancy, enhancing network reliability in critical applications where uptime is essential.
The PLX31-EIP-SIE is widely used in scenarios requiring integration between Rockwell and Siemens control systems, such as:
- Factory Automation: Connecting Rockwell PLCs controlling production lines with Siemens S7 controllers managing auxiliary equipment (e.g., conveyors, packaging machines).
- Process Control: Integrating EtherNet/IP-based sensors and actuators with Siemens S7-based process control systems in industries like oil & gas, pharmaceuticals, and food & beverage.
- Legacy System Upgrade: Facilitating the migration from Siemens S7 systems to EtherNet/IP networks (or vice versa) by maintaining communication between new and existing equipment.
- Machine-to-Machine (M2M) Communication: Enabling data sharing between standalone machines from different vendors in a unified automation ecosystem.
