PLC-5 EtherNet/IP™ Interface Module



The Allen-Bradley PLC-5 EtherNet/IP Interface Module (1785-ENET Series C) adds an Ethernet port to a PLC-5 processor. This port provides embedded TCP/IP communication capabilities that lets the PLC-5 processor communicate with other PLC-5 processors with Ethernet ports and with host computers. Adding this Ethernet port onto these PLC-5 processors provides the integration of Allen-Bradley architecture into the industry-standard TCP/IP network, offering flexible open-system solutions.

This interface module adds a second Ethernet port to an existing Ethernet PLC-5 processor. This interface module plugs into the side of the PLC-5 processor and takes up the first I/O module slot.

Benefits

• 10/100 MB high-performance peer-to-peer auto negotiate communication via an Ethernet port using PLC-5 message instructions.
  
• Through Rockwell Software RSLinx™ or INTERCHANGE Software in a computer with OpenVMS, Windows, or HP-UX operating systems, application programs can communicate directly across an EtherNet/IP network to PLC-5 processors with Ethernet ports.
  
• Programming locally (RS-232 or DH+) or remotely (DH+ or EtherNet/IP) via Rockwell Software programming software.
  
• Standard Simple Network Management Protocol support for network management.
  
• Supports remote I/O pass-through commands.
  
• Event driven e-mail messages using ESMTP (requires RSLogix 5 V7.0 or later).
  
• RJ45 connector allows direct connection to CAT5 network cabling.
  

Built-in Web Services

Ethernet PLC-5 processors (1785-L20E, -L40E, and -L80E), and the EtherNet/IP interface module (1785-ENET) provide built-in web capabilities:

• Web Diagnostics and Module Information lets a standard web browser access information stored in the PLC-5 processor data table, including module diagnostic information (requires RSLogix5, version 5.2 or later).
  
• Web User Provided Pages allow for unique Web page creation to provide custom data table information. Any Internet user who has network access to the PLC-5 processor can view these pages, which can be either HTML pages that contain data table elements, text and images, or Custom Data Monitor pages that contain data table elements in table form.
  
• Domain Name Service (DNS) lets Internet users access the built-in Web server by a specified name instead of by IP address (requires RSLogix5, version 5.2 or later).
