 Choosing between a single chip microcomputer and a PLC for industrial control applications depends on a number of factors, including the complexity of the control system, the required level of reliability and robustness, the cost constraints, and the required speed and accuracy of control. Here are some general guidelines to consider: Control system complexity: If the control system is relatively simple, with a limited number of inputs and outputs and basic logic requirements, a single chip microcomputer may be sufficient. However, if the control system is complex, with a large number of inputs and outputs, complex logic requirements, and the need for real-time operation, a PLC may be a better choice. Reliability and robustness: PLCs are designed for industrial control applications and are built to withstand harsh environments, including temperature extremes, humidity, and electrical noise. Single chip microcomputers may not be as robust and may not be able to withstand the same l...

 PLCs and microcontrollers are both types of programmable electronic devices, but they are designed for different applications and have different characteristics. Application: PLCs are typically used in industrial control applications to automate manufacturing processes, while microcontrollers are used in a wide range of applications, including consumer electronics, robotics, and automotive systems. Programming language: PLCs are typically programmed using ladder logic or other programming languages that are specifically designed for industrial control applications. Microcontrollers are programmed using a wide range of programming languages, including C, C++, and assembly language. Input/output: PLCs typically have a large number of input/output (I/O) points, which allow them to interface with a wide range of sensors and actuators. Microcontrollers typically have a smaller number of I/O points, but can be used with external peripherals to expand their capabilities. Real-time operat...

 A PLC (programmable logic controller) is a device that can control and automate industrial processes and machines. A low-end PLC is usually cheaper, smaller and simpler than a high-end PLC, but it may have less features, memory and performance. Some factors to consider when choosing a low-end PLC are: Your application requirements: What kind of tasks do you want the PLC to perform? How many inputs and outputs do you need? How fast and accurate do you need the PLC to be? How complex is your logic program? You should choose a PLC that can meet your minimum requirements without wasting resources or money on unnecessary functions. Your budget: How much can you afford to spend on a PLC? Low-end PLCs vary in price depending on their brand, model and specifications. You should compare different options and look for discounts or promotions. You should also consider the total cost of ownership, including installation, maintenance and upgrades. Your compatibility: How well does the PLC work...

 PLC and DCS are two different types of control systems that are used in industrial automation applications. While both systems are used to control and monitor industrial processes, they have some important differences in terms of their design, function, and application. Design: PLCs are designed as standalone controllers that can be used to control a single machine or process. They are typically used for discrete control applications, such as controlling motors, sensors, and other devices in a manufacturing process. DCS, on the other hand, are designed as distributed control systems that can be used to control and monitor multiple processes or machines across an entire plant or facility. They are typically used for process control applications, such as controlling temperature, pressure, and flow in a chemical plant or oil refinery. Function: PLCs are typically used for discrete control applications, where the process involves discrete events or steps, such as moving a conveyor bel...

 Interposing Relay is the auxiliary relay which is used to isolate the two different systems / devices. This could be because they have different 0V references, different voltages, AC vs. DC. Interposing Relay We discuss the interposing relay with two cases, as discussed below : Case-I Suppose we want to operate a Contactor through PLC Panel having Coil Voltage 230 V AC, But PLC relay Output Voltage is 24 V DC. In this case we require a Interposing relay Having Coil Voltage 24 V DC but its contact rating should be 230 V AC. So PLC relay will operate interposing relay first & then through its Auxiliary contacts We can Operate Contactor easily. Case-II For example, let’s say the relay of a PLC can only avail 1 A at 110 VAC, but the Controller which is to be connected to the relay requires 3 A at 110 VAC. In this case, an interposing relay with contacts rated for operation at 5 A(>3 A) at 110 VAC would be used as an interposing relay “between” the PLC relay and the Controller. ...

  Redundancy in the English language means “the state of being not or no longer needed or useful” but in Industrial Automation systems, it has an important and critical function to execute. So today are we going to understand the concept of  Redundancy  and how could this concept help us to build a better Automation solution. What is meant by the Redundant Automation System? Redundancy is about having backup components in a system that can take over if and when the primary components fail. Redundant Automation Systems basically consist of two major elements (Master & slave) or we can call them (primary component & secondary component). These two components are supposed to perform the same function but they have some priorities. The primary component is responsible for handling the function and once it fails the backup (secondary) component takes its place to handle the same function without any stoppage. The Need for Redundancy The objective of using redundant aut...

 In the last article, we discussed the most common type of PLC used in large-scale industries i.e. AB PLC (1756 ControlLogix). ControlLogix Architecture Today we will discuss about its architecture. As seen in the picture, the control system consists of power supply modules, communication module, controller (1756-L55xx), redundancy module, ControlNet communication modules (1756-CNBR), remote IO modules & some other modules like flex IO & AC drive module. As we are aware that a system has 2 controllers and the system we are talking about here also has 2 controllers installed in 2 different chassis. In the above picture, you can find the primary and secondary ControlLogix chassis. The controller (CPU) can be identified by a key slot given on it. The CPU has 3 different modes like RUN, REMOTE RUN & PROGRAM. Redundancy can be established through redundancy modules installed in both chassis connected through Fiber Optic cable. It is shown in the red color line in the above p...

 The most basic concept about learning is “If you want to have a deep understanding of any system, you have to go into detail with it”. If you are a real Automation Engineer you will not be satisfied with the simple basic information about PLCs. Instead, you will always need to go further for deep details about the CPU of a PLC, how does it work? what is meant by a SCAN CYCLE? and how could this concept (SCAN CYCLE) help us in programming? If you have already all of these questions in your engineering mind so this post is made special for you … Enjoy. What is meant by a SCAN CYCLE? In general, a PLC scan cycle is a repeatable list of executable tasks, the list can vary in size and the tasks can vary in nature and the cycle time varies based on performance and configuration. It really depends on which PLC you are using. They all do it slightly differently and it’s important to know the difference. In most PLCs, a scan cycle is the cycle in which the PLC gathers the inputs, runs your...
