The configuration methodology remained similar to Citect for DOS but became more intuitive under MS Windows. Citect for Windows was written as a direct response to a request by Argyle Diamonds . The company was originally intending to use a Honeywell system until a number of Arygle's site engineers talked Argyle around to Citect after ...
In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.
The DNP3 protocol is also referenced in IEEE Std. IEEE 1379-2000, which recommends a set of best practices for implementing modern SCADA Master-RTU/IED communication links. These include not just encryption but other practices that enhance security against well known intrusion methods.
The security of IEC 104, by design has been proven to be problematic, [2] as many of the other SCADA protocols developed around the same time. Though the IEC technical committee (TC) 57 have published a security standard IEC 62351 , which implements encryption tunneling and network monitoring in an effort to address attacks such as packet ...
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.

Substation Configuration Description (SCD) file: This is the file describing complete substation detail. It contains substation, communication, IED and Data type template sections. An .SSD file and different .ICD files contribute in making an SCD file.
Today the functionality of Supervisory control and data acquisition (SCADA) and DCS systems are very similar, but DCS tends to be used on large continuous process plants where high reliability and security is important, and the control room is not geographically remote. Many machine control systems exhibit similar properties as plant and ...
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 ...
