Distribution automation remote terminal unit
First Claim
1. A distribution automation remote terminal unit (DARTU) for a control system having a master control station communicating with plant installations each having one or more DRTUs having some or all of the system functions of measurement protection control and communications and including suitable memory and signal processing means for said functions wherein the distribution automation remote terminal unit comprises:
- at least two separate independently operable units with separate power supplies, each of the units performing a different system function to the other unit;
an inter-unit communication means including an Input/Output port on each separate independently operable unit for inter-unit communication; and
only one of said units includes means for communicating with the master control station.
