SCADA HMI is the most important component for software selection

The HMI or Human User Interface is one of the most important things in the handling of software, specially a new setup. When you are starting a new industry, factory, research or experimental lab, plant etc, then one of the systems which will be an impeccable part of any modern setup will be a SCADA system. The SCADA software which is a must have to monitor and supervise a system based on real time acquired data should have one very important feature in it, and is it’s HMI. A software gets popular not just for the working, but for its ease of use and understanding.

A demo solves the problem

Some screenshots of the software and a demo of the application can do a great job is setting expectations. After all it will be a small or big team of staffs in your company or plant who will be handling the software every day or every hour. And this team will be the same team who knows everything about the production and control of the plant or lab machinery. Therefore these same people will have to be trained to handle and use the software too in every way that is important. Hence user friendliness is much needed, and this team must be confident and sure after seeing the demo and screenshots that they will be easily able to handle the SCADA software.

The HMI SCADA testing is one of the most crucial parts of software selection. If you want to be accurate with this part you need people for testing. The men who will be handling it need to test it first, and assure you that they are comfortable.
SCADA is the future of any process of production, that involves machinery and maintenance of optimum temperature, air conditions etc, for production. And every industry has a deep dependency on these software applications.

Modbus Serial Communications Protocol Making Data Acquisition and Management More Effective

Modbus is a very effective serial communications protocol, which is published by Modicon in 1979, the company later converted to Schneider Electrical . This module is basically used in programmable logic controllers (PLCs). Soon after its release, Modbus has become the simplest and most robust de facto communication protocol in industrial automation.

The major advantages making Modbus the default communication protocol for a wide spectrum of industries are;

It is custom developed to be compliant with all standards industrial applications.
Modbus is open source without royalty free, to be acquired and customised by anyone.
So easy to deploy and maintain.
Not much restrictions on vendors and users.

What Modbus does?

Modbus helps in enabling effective communication and data acquisition in an industrial network with many devices interconnected to the same network. A classic example for such data communication can be a system which measures the temperature and humidity in a plant and then communicating that result to a computer. Modbus is now mostly used to a supervisory computer which has a remote terminal unit (RTU) in a typical supervisory control and data acquisition (SCADA) system.

Building Modbus application unit

To build a Modbus application data unit, the users need to first initiate a Modbus transaction modality. This is a function which informs a server as to what kind of action to be performed. This works in a Master to Slave mode as when the Master sends a message to Slave, this function cold field informs the server on what action to be performed next. There are also options to define multiple actions simultaneously.

The Modbus messages on serial connections are constructed in such a way that it allows the receivers to detect the beginning and end of the message easily. Usually, to identify the start of a message, a colon sign ‘:’ is used. If you are planning to install Modbus, then a bit more intensive research about its functionality is high advised.

SCADA Systems – A Few Things for the Beginners to Know

SCADA refers to a centralised system, which is meant to monitor and control complex industrial systems distributed over an extensive area. A typical SCADA system can act as a decisive link between an industrial plant and its distribution network. Say for example, a typical SCADA system will ensure adequate functioning of a power plant and the distribution network of national power grids.

SCADA control functions

The host control functions of SCADA systems are usually restricted to supervisory level interventions. Say for example, a typical PLC system may be used to control the flow of coolant to a section or the plant, whereas a SCADA system will enable the operators to alter the set points to plan the flow and set alert conditions to be recorded. The major advantage of SCADA is that it enables remote administration, which when integrated with PLC makes management of a large plant just a breeze.

SCADA subsystems

A typical SCADA system comprises of many subsystems as;

An HMI (Human-Machine Interface), which is an apparatus that processes data for the human operators to take informed decisions.

A computer system to acquire data and process it to send commands.

Remote terminal unit/s (RTUs), which ideally connects to the sensors to access the signals and convert it to digital data to be sent to the supervisory system.

Programmable Logic Controllers (PLCs), which are field devices for various purposes that can be customised based on purpose.

Communication infrastructure to connect the supervisory system to remote terminal units to access data and transfer information.

SCADA systems are usually comprised of a widely distributed database that is known as tag database. Such databases are made of elements called tags or points. An element represents a single input or output (I/O) value, which is monitored or controlled using the central system.

Overtime, SCADA systems are largely advanced and now there are web-based and cloud-based SCADA applications to ensure more flexibility, customisability, and these also eradicate the previous restrictions on geographical restrictions, time constraints, and accessibility.

In fact SCADA has become indispensable to all types enterprises ad are adding in the smooth running of the operations. It is implemented in supermarkets, waste water treatment plant, refinery and even in many households.

How does it work?

Several hardware and software elements are implemented to monitor, accumulate and process data. With the help of this automated system, it is possible to interact and operate variety of machines and wide range of devices including motors, valves, pumps and more. These machines and devices are connected to HMI (human-machine interface) software.

All events are recorded in a file which makes it easier to track down any errors in case of a snag.

Information can be provided either manually or through sensors which are then sent to RTUs (remote terminal units) or PLCs (programmable logic controllers).  The SCADA software loaded in computers then processes this information. The raw data is analyzed to help operators derive meaningful information that helps them to eliminate waste and make the operations more efficient.

Since the manufacturing processes are refined there is savings in terms of money and time.
