SCADA Development

04/12/2017 1:59 AM

How do I link a process loop, from the field instrument to the PLC and then to the SCADA in a block diagram?

In accordance with the organisation's standard procedures for so doing.

If you don't already know, why are you working on that?

Some information on the organisation's standard practices would obviate the need for such an output.

How rude.

Good luck. Why don't you draw some rectangles, label each one, and draw pencil lines between them with conductive ink. Does that work for you, rude bastage?

You can find no examples of this being shown on other diagrams within and outside your organisation?

First, search youtube.

Every maker/brand has their own HMI platform interfaced with their PLC. All you have to do is pick and select preset designs and functions (block representation) in the library. (This is also a business, you know).

If you want to interfaced your monitoring and control in other HMI or web based application, you need to start from scratch (This means you need to know programming language like Java, Visual Basics, C#, C++, ASP.net, etc)

You didn't mention COBOL++. OOPs.

I had COBOL in high school along with FORTRAN. Never used either since.

FORTRAN is great for scientific computations and so it is quite often used with supercomputers. COBOL: does anyone even use that anymore?

(ps: COBOL++ was a joke. Making COBOL object-oriented is akin to putting lipstick on a pig )

I do not know why, there are many brilliant computer scientist out there. Every now and then, better version of software and protocols is out and we have been always outdated with it.

Honestly speaking, I just made it only at the surface(only to describe) of some of them.

I always preferred Turbo C and C++ with that DOS Box, now there is matlab, phyton and a bunch of them I am not worthy to mention.

*Python. In the World of Greyhawk (a campaign setting) for the Dungeons & Dragons roleplaying game, Phyton is the Suel god of Nature, Beauty, and Farming. Phyton is also an excellent hacker. In fact, Phyton became the stuff of legend after successfully breaking a COBOL program. Basically he did nothing and was quite successful.

A phyton is also a structural unit of a plant consisting of a leaf and its associated portion of stem and so, in this sense, it could be considered part of a data structure called a tree.

Python, on the other hand, is a nifty programming language named after the Monty Python comedy troupe. In fact its editor is called Idle, in honour of troupe member Eric Idle.

Look up loop sheet, some industries embrace these, others just do point to point wire diagrams, pretty useless for the end user. You don't really need conductive ink for the lines, tho.
