PLC, or Programmable Logic Controller, is a key component in industrial automation and control systems. It serves as a digital computer that is designed to control and monitor different processes within manufacturing environments. PLCs are widely used across various industries to enhance efficiency, improve productivity, and ensure reliable operation. Here are five paragraphs to provide an overview of PLCs.
This article shows how Rheonics inline process viscometer SRV and inline process density meter SRD support most of the leading PLC in quick integration of viscosity, density and temperature data over various digital and analog protocols.
Rheonics sensors support natively a multitude of analog and digital communication protocols from 4-20mA, HART, Ethernet/IP, Modbus RTU/TCP, Profinet to CAN and soon to be available IO-Link. Check the PLC you pan to use and see examples of how Rheonics sensors have been successfully connected to them.

Introduction to Programmable Logic Controllers (PLC)
PLCs were initially developed as replacements for relays and timers used in automated control systems. They have evolved into powerful devices capable of executing complex control operations. A typical PLC consists of a central processing unit (CPU), input and output modules, memory, and communication interfaces. These components work together to receive inputs from sensors, process the data, and generate outputs that control actuators and other equipment.
Functionality and Programming of PLC
PLCs are programmable and highly flexible, adapting to various applications in industrial settings. They can be programmed using specialized software, often based on ladder logic diagrams that represent the control logic graphically. The programming language allows users to define the desired behavior of the system, such as sequencing, timing, and logical operations. PLCs can handle multiple inputs and outputs simultaneously, making them suitable for complex control tasks.
Applications of PLC
PLCs find application across a wide range of industries, including manufacturing, automotive, food processing, and energy. In manufacturing, PLCs are used to control assembly lines, robotics, and machine tools. They enable precise coordination, fault detection, and synchronization of equipment, leading to increased productivity and reduced downtime. PLCs are also utilized in process control applications, such as temperature, pressure, and level control, ensuring efficient and safe operation. In addition, process measurements like density, viscosity, flow rate, and similar process fluid and operational parameters are fed to PLC so they can be recorded, analyzed, and decisions made based on them.
