Scada Programming

SCADA is software which is designed to control the operation in visual way. Supervisory Control and Data Acquisition (SCADA) can communicate with PLC and execute its program by itself. The program is transferred to HMI instruments and we can control the system from anywhere at its range of communication. At present time Human machine interface (HMI) makes remote access to our control system.

Its popularity increases day by day. There are various company launched SCADA software but in popularity we have two SCADA software….

1. RS View
2. INTOUCH

First we are going to discuss about RS View.

RS view 32 is launched by well known company ROCKWELL AUTOMATION. ROCKWELL AUTOMATION is one of the leading company in PLC industries.

HOW TO START

You should install software RS VIEW 32 (If you don’t have it then give reply on comment with your mail id) then open it.

GO to File--> NEW-->SAVE NAME OF FILE (EXAMPLE: RITESH)-->DISPLAY-->OPEN FILE

Now you can see a blank page with lots of tools.

Program: Making Toggle switch

Use “Button” bar then scroll it on your page.

GO TO ACTION--> SELECT TOGGLE--> TAG A NAME (EG: A)

TAG
NAME	TYPE	SECURITY
EG: A	SELECT DIGITAL FOR DIGITAL ( 0,1) SWITCH ANALOG FOR CONTINUES INPUT (eg Slide) FOR CHARACTER SELECT STRING	DO NOTHING
Description	DO NOTHING (BLANK)
DATA Source (Type)	(.) Device	() Memory
Initial value	DO NOTHING

Let us suppose we give a Tag name “A” and selected digital type and no security. Now go to UPPER APPEARANCE ( if you exit then right click on button-->edit-->upper appearance) --> write ON and select pattern Solid-->Go to Down appearance -->write off and pattern solid.

Your switch is ready. To check it you should select any device operated by this switch.

You can see many patterns on bar like CIRCLE, TRIANGLE, RECTANGLE etc. Choose any. Let us suppose we are choosing Circle.

Click on circle-->make a circle (1) on your page where we made a switch.

Right click on CIRCLE (1)--> GO TO ANIMATION -->> SELECT COLOR -->GIVE TAG NAME OF SWITCH “A” (AS WE SUPPOSED BEFORE)-->> SELECT COLOUR AT ON (1) and we select red --> SELECT COLOUR FOR OFF (0) and we select green-->OK.

Our operation is done but for testing of switch we also use Numeric display which shows switch is on or off.

There is Numeric display (#) on the bar select it à Drag on paper and make small rectangle--> Give a tag name of Switch “A”--> OK.

We did all the operation for project.

Now you can run (simulate or online) your project.

If you click on switch then the circle changed to RED and again click on switch then circle changed to GREEN.

WE DONE IT.

PROGRAM: TOGGLING TWO SWITCH AND TWO LIGHT

In your previous program, add another switch and tag its name as “B”.

 Make another output device (circle2) --> RIGHT CLICK ON IT-->GO TO ANIMATION-->SELECT COLOUR-->TAG  NAME CHANGED AS “ B AND NOT A”. -->SELECT COLOUR FOR ON(1) AND WE CHOOSE RED-->SELECT COLOUR FOR OFF (0) AND WE CHOOSE GREEN.

Now right click on circle (1)-->GO TO ANIMATION-->SELECT COLOUR-->CHANGE ITS TAG NAME FROM “A” (We assumed before) to “A AND NOT B”-->OK.

Now go to run (simulate or online). If we click on switch A then Circle (1) goes RED and Circle (2) goes Green. Again click on switch a then Circle (1) goes GREEN and Circle (2) goes RED. It has similar result for Switch “B”.

WE DISCUSS MORE FUNCTION OF IT WITHIN A DAY SO PRACTICE IT GUYS.
