The Ethernet/IP™ Class1 Communications module provides I/O Scanning and I/O Emulation, on top of a Ethernet/IP™ Class3 emulation of a Logix™ processor. (Controller tags and user-defined data types.) Logix-style Produced and Consumed Tags are a planned future feature.
The base module offers Ethernet/IP™ passive Target operations to a virtual backplane of up to 100 slots. Each "Ethernet/IP Class1 Host Device" created in Ignition's OPC-UA server occupies one slot, and may claim one or more of the server's IP addresses to listen on. Each device instance will expose its configured tags in Logix v21 format to other PLCs and to Logix v21 communications drivers in other devices. Other Ignition servers can use their Logix v21 driver to communicate with this driver's virtual devices.
Passive Target operations include emulation of the virtual Logix "CIP-MODULE" I/O module inside of the Logix generic "ETHERNET-BRIDGE" ethernet I/O device. While only one device in this driver can claim a given IP address in the server, the virtual backplane functions make the other slots available for all passive operations. Simply specify the slot number in the originator.
I/O Scanning is a premium function activated on a per-slot basis with a feature code tied to the base module's license, and providing a unique device serial number. Compliant Ethernet/IP™ implementations must have unique originator serial numbers. The simplest feature code enables a non-redundant server to scan I/O from a single IP address claimed by that slot. Other feature codes can enable more outbound IP addresses, redundant licenses, and extended-duration trials.
