KTC SCADA Package

KTC SCADA System, developed in Dispatching Department of Kerman Tablo Co. is the only SCADA software produced in Iran. KTC SCADA software package is a flexible full-featured industrial automation product that can meet the requirements of any enterprise’s supervisory system in a single integrated package. It is extremely versatile and scaleable, accommodating a broad range of systems from a few hundred points to very large multi-regional systems with hundreds of thousands of points. The client-server architecture can be configured as a single site system, or partially distributed multi-server, multi-client systems with extremely high availability. 

 

Take advantage of the following functionalities and features included in KTC SCADA: 

 • Open standards

 • Versatile, scalable and flexible architecture

 • Modular software

 • High reliability, stability and quality

 • Systems integrity

 • Multiple open hardware and software platform support

 • Redundant servers with automatic fail over

 • Redundant network data paths and remote communications links

 • Real-time databases

 • SQL data interchange

 • Logic and custom control

 • VB Script/J script language support

 • Trends, graphs, events and historical archive

 • Time-stamped history data recording and trending

 Some of the features of KTC SCADA are: 

 

Modular Structure:

To take advantage of scalability and redundancy, KTC SCADA software is designed to be modular. Each module or subsystem independently runs certain controlling and monitoring tasks during system runtime. All system data operations are handled and controlled by subsystems. Different subsystems may be executed on one machine or more. All inter-subsystem communication is handled by SCADA gate.  SCADA gate is a cross platform active library and its major task is to provide inter-Subsystem interface by means of reliable UDP sockets through multiple network connections. It supports detection of network connection failure and automatically switches the network path to the destination subsystems. The double LAN protocol of SCADA gate guarantees no data loss including alarms and events in case of a network failure.

 

Redundancy:

Every subsystem optionally has an identical subsystem working in parallel as a hot standby subsystem that runs on a separate hardware. During normal operation, standby subsystems update their own database. As soon as the main subsystem crashes, its mutual subsystem continues functioning as main and the system automatically tries to recover the failed subsystem in standby mode.    

  

Scalability:

Each subsystem performs its own tasks independently. As subsystems exchange data through SCADA gate, it doesn’t matter whether they all run on one machine or not. KTC SCADA subsystems are distributed by function. This feature gives the system the following capabilities:

 • Run different subsystems on arbitrary machines.

 • Scale system to a desired capacity with very little change in existing configuration and consequently minimum expense.

 • Add new hardware as the system under control expands.

 • Extends system lifetime. Since subsystems may run on separate machines the system can easily grow with the needs of the costumer. 

 

Open System Standards and Operating Systems:

The open architecture of KTC SCADA provides an easy access to the system, it is designed to support Open standards such as ODBC (open database connectivity) and OPC (OLE for process control). Main SCADA subsystems are available on the industry standard operating systems such as UNIX, Solaris, Linux, Windows NT/2000/XP, 2003 operating systems over IPC, SUN, HP and other machines. Choice of database is also open to Microsoft SQL Server, Oracle and Postgre SQL.

 

 Standard Development Tools:

 Standard development methods, languages and tools are used in order to provide systems which are hardware-supplier independent and can be easily and cost effectively ported to new hardware platforms or operating systems. This enables also the integration of other software in an efficient way. 

 

 Man-Machine Interface:

The graphical user interface (GUI) of KTC SCADA represents one of the most advanced SCADA operator and system manager interfaces. To be fully compatible with open standards, the GUI is based on Microsoft Windows, de facto standard.   User interface features can be summarized as below:

 • Multi-windowing

 • Multi-monitoring

 • Point and shoot capability

 • High performance zooming and panning  

 • Fast find capability for searching process objects in all windows  

 • Minimizing and maximizing (all Windows display features)  

 • Real-time multicolor Trend drawing for analog value fluctuations  

 • Event viewer for both control system and SCADA center featuring sorting and filtering by Event Fields  

 • Alarm list with process diagram connectivity  

 • Full WYSIWYG printing capability (including multi-page printing) for all process diagrams and lists as well as generating picture files  

 • Complete object library for process object visualization with capability for designing new object   

 • Group alarming   

 

 Trend:

 This software is designed to plot real-time graphs for analog points. The operator can select one or even several analog points (with different colors and styles) to follow the value variations during a time period.
