1756-L85E: ControlLogix 5580 Processor 40MB USB/EtherNet
The 1756-L85E is the ControlLogix 5580 Processor 40MB USB/EtherNet covered on this page. The attribute that decides whether it fits the existing installation without modification is 6.2 Watts.
This configuration's controllogix 5580 processor 40mb usb/ethernet is the attribute that drives the replacement decision. A communication or network module is judged by the protocol it carries and the bus it joins, not by its catalogue headline. controllogix 5580 processor 40mb usb/ethernet sets which controllers and field devices it can bridge, and the isolation and termination it provides. Matching 6.2 Watts against the existing network topology avoids a module that fits the rack but cannot talk to the rest of the system.
