High-end Programmable Logic Controller

High-end Programmable Logic Controller – Schneider PLC

In the first part, we overviewed the PLC’s used for smaller and medium applications. The second part overviews the PLCs used for higher-level applications.

M340 – Mid Range PLC

The first range of high-end processors in Schneider PLC starts with M340 PLC.

It is a very powerful and compact series of PLCs providing high-end efficiency and control solutions in it.

This PLC has a program memory of 4 MB, 128 MB of file storage, and executes 7 instructions in a millisecond. The PLC is a modular type which means it requires a rack to configure.

The communication part comprises a USB port, 3 Ethernet networks, 1 CAN Open, 1 serial port, 4 ASI, and 37 Modbus buses.

The PLC has an embedded web server and file transfer protocols. The main advantage is that the program is stored in a removable SD card.

So, whenever the PLC gets corrupt or damaged, just remove the SD card and insert it in the new PLC.

The software used for programming is Control Expert. You have all the languages available in it.

M580 – Ethernet Programmable Controller & Safety PLC

It is one of the highest-end levels of CPU available in Schneider PLC. It is a smart PLC designed for big manufacturing applications, compatibility with Industry 4.0, and complex hybrid production lines.

A large amount of data flow involved and provision to add multiple communication devices of various types and vendors in it makes it a very suitable PLC for big scale applications.

It has redundant controllers and safety controllers (SIL3) with native Ethernet and cyber-security embedded in it.

The software used for programming is Control Expert. You have all the languages available in it.

Preventa XPS MC, XPS MP – Safety controllers

This PLC is a safety controller comprising various safety applications. The PLC is Category 4 conforming to EN 954-1 and SIL3 conforming to EN/IEC 61508.

It has 30 types of certified safety functions and libraries built in its programming software. It communicates to PLCs via Modbus, CAN Open, or Profibus network.

Schneider range of controllers also has a vast range of distributed IO’s and racks and modules for fail-safe, efficient and hybrid types of communication and programming. It has other controllers and devices too, but we will not cover all the types in this post. I have attempted to cover the most and generally used types of PLCs in Schneider.

In this way, we had an overview of the various types of Schneider PLCs in both the posts; ranging from small-scale to large-scale applications.

PLC Program for Mixing Tank

Create a ladder diagram for controlling a batch mixing process. Implement a PLC program for mixing tank or Mixing Process using PLC Ladder Logic. PLC Program for Mixing Tank Fig : Mixing tank A tank is used to mix two liquids. The required control circuit operates as follows: A. When the START button is pressed, solenoids A and B energize. This permits the two liquids to begin ﬁlling the tank. B. When the tank is ﬁlled, the ﬂoat switch trips. This de-energizes solenoids A and B and starts the motor used to mix the liquids together. C. The motor is permitted to run for 1 minute. After 1 minute has elapsed, the motor turns off and solenoid C energizes to drain the tank. D. When the tank is empty, the ﬂoat switch de- energizes solenoid C. E. A STOP button can be used to stop the process at any point. F. If the motor becomes overloaded, the action of the entire circuit will stop. G. Once the circuit has been energized, it will continue to operate until it is manually stopped. Solution...

What is Relay? How it Works? Types, Applications, Testing

We use relays for a wide range of applications such as home automation, cars and bikes (automobiles), industrial applications, DIY Projects, test and measurement equipment, and many more. But what is Relay? How a Relay Works? What are the Applications of Relays? Let us explore more about relays in this guide. What is a Relay? A Relay is a simple electromechanical switch. While we use normal switches to close or open a circuit manually, a Relay is also a switch that connects or disconnects two circuits. But instead of a manual operation, a relay uses an electrical signal to control an electromagnet, which in turn connects or disconnects another circuit. Relays can be of different types like electromechanical, solid state. Electromechanical relays are frequently used. Let us see the internal parts of this relay before knowing about it working. Although many different types of relay were present, their working is same. Every electromechanical relay consists of an consists of an Elect...

Chlorine dioxide Analyzer Principle

Chlorine dioxide measurement Chlorine dioxide (ClO2) is an instable, non-storable, toxic gas with a characteristic scent. The molecule consists of one chlorine atom and two oxygen atoms – represented in the chemical formula ClO2. It is very reactive. To avoid the risk of spontaneous explosions of gaseous chlorine dioxide or concentrated solutions, it is generally handled in dilution with low concentrations. ClO2 is soluble in water, but tends to evaporate quickly. Typically it is prepared on site, for example from hydrochloric acid and sodium chlorite. The procedure provides solutions with approx. 2 g/l ClO2 that can be safely handled and stored for several days.
