1. Core Overview
The PLX51-DF1-ENI serves as a communication bridge that connects legacy devices using the DF1 serial protocol to modern EtherNet/IP networks. It is ideal for integrating older automation equipment into contemporary industrial control systems.
Key functions include:
- Protocol Conversion: Translates DF1 data to EtherNet/IP and vice versa, enabling seamless data exchange between different network types.
- Multi-Device Support: Handles communication with multiple DF1 devices simultaneously, suitable for centralized management of legacy equipment.
- Replacement Solution: Acts as a drop-in replacement for Rockwell Automation’s discontinued 1761-NET-ENI module.
2. Technical Specifications
- Interfaces: DF1 serial port and EtherNet/IP Ethernet port.
- Power Supply: 24VDC, compliant with industrial power standards.
- Communication Speed: Supports standard DF1 baud rates for broad compatibility with legacy devices.
- Environmental Ratings: Industrial-grade construction for reliable operation in factory floor conditions.
3. Product Features
- High Compatibility: Works with Rockwell Automation’s SLC 500, CompactLogix, and MicroLogix series, as well as DF1-enabled devices from other manufacturers such as Honeywell.
- Easy Integration: Simplifies the migration from serial-based systems to Ethernet without requiring a full replacement of legacy hardware.
- 24/7 Technical Support: ProSoft provides round-the-clock assistance, especially for critical plant-down situations.
4. Structure and Components
- DF1 Interface: Serial port for connecting legacy equipment.
- EtherNet/IP Interface: RJ45 port for industrial Ethernet connectivity.
- LED Indicators: Show power status, communication status, and error codes for easy troubleshooting.
- Power Terminals: For 24V DC power input.
5. Typical Applications
- Legacy System Migration: Integrate older DF1-based PLCs into new EtherNet/IP networks during facility upgrades.
- HMI Modernization: Connect modern HMIs to existing PLCs without modifying the original control programs.
- Cross-Platform Integration: Link Rockwell Automation systems with equipment from other vendors (e.g., Honeywell) on a single network.
6. Installation and Maintenance
- Mounting: DIN-rail installation for standard industrial control cabinets.
- Maintenance Tips:
- Monitor LED indicators for network status and error information.
- Regularly check the ProSoft website for firmware updates to improve compatibility and performance.
- Prepare product serial numbers, system architecture diagrams, and network topology maps when contacting technical support for faster issue resolution.
