What is PLC? - A Beginner's PLC Overview Every PLC Beginner Should Know

This blog post is for beginners who are interested in learning about PLC and SCADA, but they are confuses or not sure where to start. After read this post you will be able to identify the most basic components of a PLC system and can also know about the basic purpose and function of PLCs (and PACs). In this post I have cover all the basic about PLCs (and PACs).

What is PLC?

PLC stands for Programmable Logic Controller or programmable controller are small industrial digital computers which have modular components designed to control the manufacturing processes. PLCs are often used in factories and industrial plants to control light, motors, fans, pumps, circuit breakers and any other activity that requires high reliability control and ease of programming and process fault diagnosis. To understand the purpose of PLCs better, let’s look at a brief history of PLCs.

History of PLC-

Industrial automation started well before PLCs. In the right on time to mid 1900s, automation was typically done utilizing muddled electromechanical communicate circuits. Be that as it may, the measure of relays, wires and space expected to make even straightforward automation was risky. A large number of relays could be important to robotize a basic industrial facility process! Furthermore, if something in the intelligent circuit should have been changed?

In 1968 the first programmable logic controller came along to substitute complex transmit circuitry in industrial plants. The PLC was intended to be effortlessly programmable by plant architects and specialists that were at that point acquainted with transfer rationale and control schematics. Since the starting PLCs have been programmable utilizing stepping stool rationale which was intended to imitate control circuit schematics. The stepping stool graphs look like control circuits where control is spilling out of left to directly through shut contacts to empower a hand-off loop.

In the above diagram, you can see ladder logic looks like simple control circuit schematics where input sources (switches, push-buttons, proximity sensors, etc) are shown on the left and output sources are shown on the right.

How Do PLCs Work?

There are many PLCs components, but only these below three are most important of them:

1. Processor (CPU)
2. Inputs
3. Outputs

PLCs are most complicated and powerful digital computers but here we can describe the function of a PLC in simple terms. The PLC takes inputs & performs logic in the CPU and then turns on or off outputs based on that logic.

1. The CPU monitors the status of the inputs (ex. switch on, proximity sensor off, valve 40% open, etc.)
2. The CPU takes the information that it gets from the inputs, performs logic on the inputs
3. The CPU operates the outputs logic (ex. turn off motor, open valve, etc.)

See the flowchart below for a visual representation of the steps above.

Conclusion: Now you have better understanding of what PLCs are and how they work. Now you can start your PLC course. This was basic concept and was most important to know before start PLC training.

The future of Industrial automation PLC SCADA technologies

Every industrial automation PLC SCADA project starts with the familiar process of counting I/O, selecting vendors, laying out PLC chassis, and distributing requests for quotes. And finally you are commissioning a system built on general standards, repeating the same mistakes as previous systems.

The conversations also repeat during bid review or negotiation meetings when someone points out inconsistent or outdated standards. Technology is changing so fast, and the past few years have brought technical advances that have breathed new life into Industrial automation groups and started great discussions around what the future holds. There is still a lot of work to be done.

Virtualization is a great example. Early adopters saw the benefits, and news spread like wildfire. As SCADA (supervisory control and data acquisition), manufacturing execution systems, and historian capabilities increased, so did the need for processing power, and virtualization was the perfect answer. Virtualization is now commonplace in Industrial automation domain. And many are asking what is next. The next big thing is waiting to happen. Industry has become more demanding asking for virtualized controllers and solution with mobility. But they are easily feasible with existing technology. The success of our industry depends on it.

HMI/PLC SCADA industrial automation applications have already secured their place as key components for any smart factory, IT-focused applications. Humans by nature are reluctant to give up control; however, fully automated facility does not mean a complete end of human interference on the factory. Considering the huge focus in industrial automation / automated equipment and intelligent HMI/PLC SCADA software, it is important that manufacturers invest in employee training, enabling talented engineers from industrial automation domain to focus on important tasks.

Working of SCADA System In Steel Industries

SCADA means  Supervisory Control and Data Acquisition. SCADA is a system which is used to monitoring the running process, monitoring the parameters as well as control the output and collection of data. Generally SCADA used in the control system in any of the plant where we monitor and control.

It consist of three types of station:- 

1.      Operation Station

2.      Engineering Station

3.      Server Station

Ø  In the Operation Station the operator monitors the working process and online parameters.

Ø  In the Engineering Station the specialists of SCADA develop the SCADA, modifying the SCADA requirement if required.

Ø  In the Server Station the SCADA does not work as an Operation Station & Engineering Station it just only stored in server data when in any main station.

Now a days the SCADA used in world wide industries e.g. Steel, food, oil, package cement etc. In the steel plant we does not only use SCADA but we use all Automation equipment like Electrical Motor, Instrumentation network. SCADA is depend on the programming of PLC.

The major function of SCADA in Steel plant is to Supervision, runtime controlling the field device & collect the data. Due to Industrial standards and their characteristics which very important for plant operation point of view, the SCADA system has accepted by major of the plant.

Why SCADA used in Steel Plant:-

In the Steel plant for Monitoring & controlling function SCADA is the best system, some features of SCADA system which is best in industries are given below:-

1)      SCADA system is fully computer based software which is used to control Electrical Equipment, collect & store very large amount of data.

2)      SCADA system allows to plant engineer to interact real time process data from level 0 equipment, field sensors etc.

3)      The input output terminal unit which is working in remote area is the main source of process data this create online image of the system.

Advantages of SCADA system:-

1)      Easy to under stood the operation of plant, Easy to developed the plant design in SCADA system.

2)      SCADA is reliable and robust system that’s why it is used in critical industrial process environment where reliability and performance is priority. In well established framework specific development is performed by SCADA system that enhance reliability and robustness of the system.

SCADA is just the tip of the ice bug. Other tools & skills are required to fully Automate the industry’s control processor like Motor, Drive, Process Instruments, DCS, Penal Design etc. For more information:-

A post-Invensys-acquisition update

By Rick Zabel, Publisher & Editor

  Last week in Orlando, FL, Schneider Electric hosted its first Global Software Customer Conference since it acquired Invensys in January. The conference has its roots as WonderWorld, the former Wonderware company’s own user conference. Over the years, after Invensys acquired Wonderware, the conference evolved into OpsManage, a global event that emphasized all of Invensys’ software, control, and safety offerings. Since Schneider Electric's purchase of Invensys, I have been waiting to hear some news about the integration of the two companies. That news, as it relates to software, was delivered last week at the conference.

In April of this year, Schneider Electric created a new business unit called Global Solutions. Global Solutions is made up of four key offerings. One of those offerings is Software, which will continue to be led by Ravi Gopinath as Executive Vice President. The Software business consists of the legacy Invensys brands—Wonderware, SimSci, and Avantis—as well as Schneider Electric’s Citect, Ampla, and OASyS DNA (Telvent SCADA) software brands, integrated into one business.
In addition to the Software business, Global Solutions consists of the following offerings:

• Field services and product support applicable to other Schneider Electric product offerings.
• Segments, activities related to industry-specific and key account level, global sales and after-market customer relationship management.
• Digital services, which is a basket of offerings that may or may not leverage software. Examples include cyber security risk assessment services and Telvent weather forecasting service.

Global Solutions and its President, Daniel Doimo, will be headquartered in Lake Forest, CA, which has long been the headquarters for Wonderware and the Invensys software business. Doimo stressed that software is a key pillar to Schneider Electric's global strategy. "We invested in software because we have the vision," said Doimo. "We don't want to reinvent the wheel - we want to spin it faster." Schneider Electric’s Global Solutions business will deliver holistic and integrated solutions to its customers. They are committed to tailored solutions for specific industry segments. Doimo and Gopinath believe the more robust, combined solution set offers the most comprehensive portfolio to help its customers achieve operational efficiency. However, Gopinath stressed, "We are always looking for opportunities to strengthen our portfolio through acquisitions."

Improving the user experience and driving additional value are the cornerstones of everything the company does. Gopinath said the software business has and will continue to focus incessantly on improving user experience, even as the customer persona is rapidly changing. Their second focus is interoperability, which is where architecture comes into play.

Software Architecture

At the core of its software solutions, and at the lowest layer of the architecture, is a common platform called Wonderware System Platform. It is the information management framework for all of the company’s software products. It is open, scalable, and secure, and it works across multiple hardware platforms. The second layer consists of applications that perform specific functions, like HMI, historian, MES, asset management, etc.  The third layer encompasses solutions for specific industry segments.


Prior to the Invensys acquisition, Schneider Electric introduced StruxureWare, a unique software platform of integrated applications and suites that delivers visibility into energy and resource use across an organization. The StruxureWare concept and name will be used in the newly combined software business. StruxureWare will be a collection of applications or solutions that are tailored to specific industry use cases.  They will provide specific, unique functions required by industry segments. A few of these StruxureWare offerings have been defined, but they are still early in the process of defining others.

PLC Programming Introduction | Sofcon

One method of the PLC programming is using ladder diagram method. Ladder diagram consists of a descending line on the left, with lines branching to the right. This line is the line branching instructions. Throughout this instruction line consists a combination of logic that states when and how the existing instructions on the right side are done.

Ladder Diagram Example

The logic combination of ladder diagram as following:

A. Instruction LOAD (LD) and LOAD NOT (LD NOT)

The first condition that starts any logic block in the ladder diagram associated with LOAD instruction (LD) or LOAD NOT (LD NOT). Each of these instructions requires one line of mnemonic code.

B. Instruction AND and AND NOT

If two or more conditions that are connected in series on the same instruction line, then the first condition using LD or LD instruction and the remainder NOT use the instructions AND or AND NOT.

AND instruction can be imagined to produce ON if both conditions are linked with this instruction in all ON conditions, if any one in the OFF state, let alone both OFF, the instruction will always result AND OFF too.

C. Instruction OR and OR NOT

If two or more conditions connected in parallel, meaning in a different line of instructions and then joined again in the same instruction line, then the first condition associated with LD or LD instruction and the rest is NOT related to the instructions OR or OR NOT.

In this case imaginable OR instruction will always result in ON execution condition when any one of two or more conditions connected with this instruction in the ON condition.
