PLC-5 Controller Choices 15
1785-SO036C-EN-P - April 2002
Ethernet PLC-5 controllers The Ethernet PLC-5 controller integrates the Allen-Bradley
architecture into an industry-standard EtherNet/IP system, offering
a flexible and open solution.
With the Ethernet PLC-5 controller’s built-in communication
capabilities, your entire enterprise can use standard Ethernet or
Internet connectivity to control and monitor production. Using the
Internet and web browser, you can create your own custom web pages
to provide executive summaries of process information. These pages
are accessible to any Internet user who has network access to the
PLC-5 processor. The embedded web server provides access to
PLC-5 diagnostics. Domain Name Service (DNS) and Simple
Network Management Protocol (SNMP) are also supported.

PLC-5 Ethernet Interface Module The PLC-5 Ethernet Interface Module (1785-ENET) is a single-slot
module that attaches to the side of any Enhanced PLC-5 series B or
later controller, Ethernet PLC-5 controller, or ControlNet PLC-5
controller to provide additional Ethernet connectivity.
Using the Ethernet Interface Module’s built-in communication
capabilities, your entire enterprise can use standard Ethernet or
Internet connectivity to control and monitor production. Using the
Internet and web browser, you can create your own custom web pages
to provide executive summaries of process information. These pages
are accessible to any Internet user who has network access to the
PLC-5 processor. The embedded web server provides access to
PLC-5 diagnostics. Domain Name Service (DNS) and Simple
Network Management Protocol (SNMP) are also supported.
