Supervisory Control And Data Acquisition SOFTWARE FOR REMOTE MONITORING
•SCADA : Supervisory control and data acquisition
•MMI : Man Machine Interface
•HMI : Human machine Interface
•This acts as an operator station. The operator can monitor as well as control the process parameters from these stations. Apart from online process data the operator will have access to historical and real-time trends, alarms and reports. The operator can give commands to control hardware for opening the valve, change the set point, start the pump etc.
The common features of SCADA include Dynamic process mimic, Trends, Alarm, Connectivity with hardware, Recipe management etc.
SCADA systems has many applications right from industrial automation, power distribution to water management.

1.No. of I/Os - Wondeware InTouch comes is 64, 128, 256, 1000 and 64,000 tags package.
2.Development + Runtime + Network (DRN) / Runtime + Network (R+N) and View Node
D+R+N: With this package development and editing of the application is possible, Runtime monitoring and control of the plant is possible and Networking is possible.
R+N: With this package development and editing of the application is NOT possible, Runtime monitoring and control of the plant is possible and Networking is possible.
Factory Focus: With this package development and editing of the application is NOT possible, Runtime monitoring is possible but control of the plant is NOT possible and Networking is possible. This package is used a view node
These are points where one protocol is translated to another. Mainly in our study they are points where TCP/IP traffic is converted to some (often proprietary) control protocol such as Modbus, LonWorks, BACNet, etc.
•InTouch: It is an application manager. Using this you can create new application. Move between various applications.
•View: Window viewer. This will start Run time application. From this you can monitor and control the plant.
•WM: WM.XE is Window maker. This will start the development package in InTouch. Using this you can you can develop the application.
•Replace : Automatically closes any window(s) it intersects when it appears on the screen including popup other replace type windows.
•Overlay: Appears on top of currently displayed window(s) and can be larger than the window(s) it is overlaying. When an overlay window is closed, any window(s) that were hidden behind it will reappear. Clicking on any visible portion of a window behind an overlay window will bring that window to the foreground as the active window.
•Popup: Similar to an overlay window except, it always stays on top of all other open windows (even if another window is clicked). Popup windows usually require a response from the user in order to be removed.
Symbol Factory contains symbols which can be readily used in the application. The symbols is contains include various Tanks, Reactor, Pipes, Icons, Flags.
