Several methods have been developed since the 1990s, most of which rely upon sensors deployed on overhead lines to measure parameters in real-time. Other systems utilize weather stations that monitor environmental conditions without contacting the line. Data received from any method is reported to a main computer for processing.
The OPC Data Access Specification is the first of a group of specifications known as the OPC Classic Specifications. [1]OPC Data Access is a group of client–server standards that provides specifications for communicating real-time data from data acquisition devices such as PLCs to display and interface devices like Human–Machine Interfaces (HMI), SCADA systems [2] and also ERP/MES systems.

Alarm conditions can be explicit—for example, an alarm point is a digital status point that has either the value NORMAL or ALARM that is calculated by a formula based on the values in other analogue and digital points—or implicit: the SCADA system might automatically monitor whether the value in an analogue point lies outside high and low ...
The goal of Advanced Distribution Automation is real-time adjustment to changing loads, generation, and failure conditions of the distribution system, usually without operator intervention. This necessitates control of field devices, which implies enough information technology (IT) development to enable automated decision making in the field ...
The HMI/SCADA Module Layer contains mainstay products of the Ignition Platform. Vision is the main visualization module, SQL Bridge is a bidirectional OPC to SQL database historian and transaction manager, Reporting generates dynamic Pdf reports, and Mobile allows access to HTML 5 compatible devices such as iPads , iPods , Android , Smartphone ...
Outage management systems are also commonly integrated with SCADA systems which can automatically report the operation of monitored circuit breakers and other intelligent devices such as SCADA reclosers. Another system that is commonly integrated with an outage management system is a mobile data system. This integration provides the ability for ...
RAPIEnet – Real-time Automation Protocols for Industrial Ethernet; Honeywell SDS – Smart Distributed System – Originally developed by Honeywell. Currently supported by Holjeron. SERCOS III, Ethernet-based version of SERCOS real-time interface standard; SERCOS interface, Open Protocol for hard real-time control of motion and I/O; GE SRTP ...
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.
