Benefiting from the CIM/CIS based API interface and application development framework on DIASI platform, the DIASI SCADA platform is able to have organic integration with specific business application in the area of advanced control application system, such as dispatcher training system, all kinds of advanced applications ensuring stable operation of power grid and safe operation of pipeline system, such as leakage detection, dynamic simulation, etc.
The development and improvement of DIASI SCADA application suite is closely related to ASAT’s application and implementation in power automation systems and SCADA system for oil & gas storage and transportation. Driven by a couple of R&D projects by National Grid and nationalization of SCADA software projects by China National Petroleum Corporation (CNPC), the DIASI SCADA system platform has matured and has formed a series of projects including embedded SCADA/HMI applications, a new generation of fully distributed power control SCADA/HMI applications, oil and gas pipeline stations control SCADA/HMI applications, regional level control center SCADA/HMI applications and other solutions. These solutions provide a few distinctive features that allow companies to see the huge benefits of implementing a new SCADA solution or upgrading an existing system:
The easiest and most effective open SCADA software solution
High available, reliable and scalable SCADA applications
The simple configuration of software redundancy
The DIASI architecture facilitates the configuration and management of the security for the operation and system, and is compatible with existing IT security mechanisms.
Enhance user design, establishment, deployment, and maintenance of standardized SCADA applications
Minimum life cycle cost for overall system
Easy to Configure, Simplified Maintenance
ASAT provides a flexible, maintainable and secure software platform for SCADA environments. Related SCADA solutions are constructed and integrated into a single, open and flexible software architecture that connects to any automation system used today, Remote Terminal Unit (RTU), Intelligent Electronic Device (IED), Programmable Logic Control (PLC), database, historical database, or enterprise system. The openness of this platform allows users to expand their existing systems without having to purchase new hardware or control systems.
ASAT's solution can disperse point-to-point communications. In addition, existing facilities can be modeled within the software. This can save an extremely large amount of time when adding new oil wells, stations, substations, equipment or other monitoring stations. This is because engineers can reuse templates that contain all the information necessary for control, such as scripting, alarms, and communications. Since the existing template of the software is verified in the field, it also greatly improves the reliability of the system.
Unparalleled Security
Security has become an increasingly important consideration, and it will continue to be critical for oil and gas and power transmission systems. ASAT’s products have been robust in terms of security to maintain a strong capability. At the same time the built-in function can carry out the safety verification at any level of automation process. ASAT provides security for the lowest possible level of data while extending the CA and RBAC-based security models to the physical device layer to protect your system.
Unlimited Flexibility in Scale
The application is flexible enough to allow companies to freely add equipment such as drilling or pumping stations, while maintaining early engineering investment and engineering work. From hundreds I/O to millions I/O, from a single node to hundreds of workstations, ASAT’s DIASI SCADA platform can always meet your current and future requirements of the system.
Simple Configuration for Software Redundancy
ASAT's DIASI SCADA provides easy-to-use and easy-to-implement software redundancy for SCADA systems. It includes SCADA server nodes, pre-device communication nodes, historical archives and HMI display redundancy. Adopt Unified Resource Management and service technology to support both centralized and distributed storage mechanisms. Only a single mouse click can complete the backup of entire system configuration resources or part of resources. Powerful version management ensures consistency in large-scale system software resources and configuration resources. This can not only increase the reliability and stability of your SCADA system, but also significantly reduces management costs.
Reducing the Total Cost of Ownership
In the development of SCADA applications, the productivity of engineering is often poorly estimated. There will be more problems when multiple development companies or system integrators are working on the same project. However, with the support of DIASI's object modeling and graphic module integration configuration technology, devices and systems in the SCADA environment can be used as object template models (classes). For a configured object that is completed by a test, once it is converted to a class template, it can be reused throughout the system. This will save a lot of time in configuration and maintenance. Meanwhile, as object information is stored as a class template, DIASI's human-machine interface browsing system provides online instantiation support for object view, which improves the integrity of the automation system and reliability of the device.
Easy to Use Report Generation
ASAT's DIASI SCADA software can also be extremely easy to create reports that meet the regulatory requirements. These reports can be automatically generated, including hourly, daily, weekly, monthly and trend charts with minimum, maximum and average value in different time range. These reports can be quickly and easily created, printed, and saved, thus simplifying the reporting process.
Visualization
ASAT's visualization software provides excellent ease-to-use and easy-to-configure graphical capabilities. The integrated configuration of graph and mode and Business-Driven View Builder, combined with the Object View Library fuction, allow users to quickly create and deploy customized applications to connect and deliver real-time information. The application can be viewed from a single monitor or multiple screens.
