First Claim
1. An intelligent electronic device (RTU) for use with a supervisory control and data acquisition (SCADA) system, the RTU comprising:
- (a) automation software;
(b) a generic encapsulation layer that interfaces the RTU hardware to said automation software (c) conversion means for measuring a physical process and converting the measurements into digital representation values of the measurement;
(d) memory for storing digital representation values;
(e) processor means in communication with said conversion means for operating upon said digital representation values according to a predetermined function;
(f) said processor further being in communication with said memory for storing the digital representation values;
(g) a bidirectional communication means in communication with said memory and said SCADA system for selectively transferring said digital representation values to the SCADA system; and
(h) a default configuration that on application of power allows immediate use of bidirectional communication means enabling the automation software to perform at least one of the activities;
meter utilities, detect abnormal operating conditions, perform data processing and control operating conditions and combinations thereof.

Abstract
Apparatus for communication for a supervisory control and data acquisition (SCADA) system, the SCADA system comprising: an enterprise server; at least one intelligent electronic device (RTU), wherein the RTU measures a physical process and stores digital data representative of the measurement in a memory area for transmission; a configuration tool (AES) linking the SCADA server with the RTU; a connection device (TAC) for installing the SCADA system on related software program; a gel encapsulation layer (GEL), the method comprising the steps of: (1) communicating a command from the enterprise server to said RTU via the AES to configure said RTU; (2) permitting said RTU to receive data input and to store said data; and (3) transmitting said data back from the RTU to the enterprise server.

6. A method for communicating with a supervisory control and data acquisition (SCADA) system from an intelligent electronic device (RTU), comprising the steps of:
-
(a) when said RTU is in a first mode;
i. measuring a physical process to obtain measured values;
ii. operating upon said physical process as required by said RTU functionality;
iii. storing said measured values in a memory area for later transmission to an enterprise server;
iv. retrieving said measured values from said memory area and transmitting said measured values to the AES;
V. using a reconfguration tool (ARME) to provide a new set of commands to the RTU;
vi. transmitting those new commands to the RTU placing the RTU in a second mode;
vii. eceiving said new commands and automatically reconfiguring itself based on those new commands;
viii. storing said commands in said memory area in place of said original RTU functionality;
ix. continuing to measure the physical process to obtain measured values;
x. operating upon said measured values as required by said RTU functionality;
xi. discontinuing the storage of said former configuration commands in said memory area; and
,xii. transmitting said new measured values to the AES. - View Dependent Claims (7, 8)
