Introduction

PLC has become a part of every modern industry. Although there are various brands that manufacture PLC, Siemens was the first company that introduced Bangladesh to PLC automation. In fact, 80% of the industries of our country currently have a Siemens PLC-based automation system. So, the technical professionals in our country must have a clear concept about the Siemens PLC-based automation system.

What is PLC?

A programmable controller (PLC) is a device that can be programmed to control other devices. A PLC constantly monitors the status of input devices. And it controls the state of external devices using logic-based decisions based on user-created programs. 

PLC is a programming device which is used for making our modern industry more dynamic and efficient.

Engr. MD. Abu Bakar Siddique

Installing and programming programmable controller devices is effortless. For efficient installation of input and output devices, most PLCs feature quick-release type screw connectors. In most situations, PLC editing features allow program modifications, revisions. Additionally, loading operations are to be completed in seconds. PLC systems are flexible, meaning that input and output devices can be swapped and replaced as needed[1].

There are many features of a PLC. These include Input/Output, Memory, A programming Mechanism, a CPU, and a Power Supply are equally important for a PLC.

How to Operate a Siemens PLC?

A clear concept of Industrial Controlling is a must to learn Industrial Automation. Moreover, knowledge of various programming languages of PLC & wiring of a PLC is also needed. Additionally, reading the manual of a PLC brand. Last but not least, one must know how to operate the operating software of a PLC. Now we will talk about these steps.

Learn Industrial Controlling Easily?

Industrial Controlling includes all kinds of wiring (house/industrial wiring). For instance, people must know the specification, selection & connection procedure of Magnetic Contactor. Similarly, Relay, various types of Timers, Sensors, etc. Similarly, people also must know about the controlling as well as the power circuit of the motor.

How to Learn Various PLC Programming Languages?

One needs to learn the languages needed to program a PLC such as Ladder Diagram (LD), Structured Text (ST), Instruction List (IL), etc. 

PLC is a programming device. So, people must learn the languages needed to operate this device. Without having a clear concept about these languages, operating a PLC is not possible. There are various languages to operate a PLC, but “Ladder Diagram” is the most popular of them all.  

Electrical diagrams show the physical connections and configuration of an electrical system or circuit. It shows the interconnection of electrical wires and where fixtures and components can be connected to the system.

Before starting learning about ladder languages, knowing about basic symbols is a must. By combining those symbols, we can easily convert an Electrical Diagram to a Ladder Diagram.

The graphical representation of an electrical control system using fewer sophisticated symbols is known as a ladder diagram. When compared to an electrical control diagram, it is simpler to comprehend. It is mostly employed in digital automation systems.

Multipurpose Engineering & Industrial Automation will hold on to its title as the best PLC training center in Dhaka, Bangladesh. And will provide detailed knowledge about Ladder Diagrams.

Wiring a Siemens PLC?

Correct wiring of input and output is needed for successful PLC operation. It may sound easy. But it is a very crucial part. Because of a mistake in the wiring process, there will be chances of damaging the motherboard of the PLC. Specifically, the motherboard of the PLC contains sensitive devices like Integrated circuits, capacitors, etc. The wiring diagram for both input and output of a PLC resides in the manual. Below a wiring diagram of Siemens s7 200 PLC is given,

This exact diagram needs to be followed for wiring the Siemens s7 200 PLC. Otherwise, hardware damage of PLC is imminent. These PLC wiring diagrams are in our PLC book. The book contains wiring diagrams of all the popular brands of PLC available in Bangladesh.

We will guide you step by step about the wiring procedure of every PLC brand available in Bangladesh.

How to Read the Manual of a Siemens PLC?

Every PLC brand has its own manual about its PLC hardware. It contains the wiring procedure of PLC, various programming commands of PLC. Also reading-writing procedure from PC to PLC and vice-versa, etc. Hence before starting to work with a PLC brand, knowing how to read the manual of that specific brand is a must.

For example, start with the table of contents. A Siemens PLC manual contains 500/700 pages on average. However, we do not have to go through all the pages. From the table of contents, we need to find out the wiring procedure, reading from Siemens PLC, write to Siemens PLC, and communication protocol.

We, the best Siemens PLC training institute in Dhaka, Bangladesh will direct you step by step about understanding the manual of any PLC brand.  

Using the Operating Software of a Siemens PLC?

One must have the operating software of the PLC he is going to work with. The hardware of a Siemens PLC is completely useless without the software. Every brand of PLC has its own software to work with. In the Software, you will do the programming using various programming languages we mentioned above. In fact, for Siemens S7 200 PLC, the software we are going to use is “Step 7-micro/win V4 SP9”. It is for Windows 10.

Please note that Siemens S7 200 software does not work on every version of Windows. It was designed for Windows 7. However, the latest version works with Windows 10 as well. Now, from our PLC Book, we will see the operating and communication process of Siemens S7 200 software.
