Abstract

An intelligent electronic device (IED) configured to supervise a process having a state has at least one of a current, voltage or resistive input configured to monitor the state of the process, a binary status input configured to monitor the state of the process, a binary status input configured to receive a digitally encoded serial communication package for monitoring the state of the process, a control output configured to output a signal to control process protection, control, or automation, or a combination thereof, or a control output configured to output a digitally encoded serial communication package to control protection, control, or automation, or a combination thereof. The IED is also configured to facilitate digital communication between at least two compatible devices by directing communication packets from ports connected to an originating compatible device to ports connected to a destination compatible device.
