At Dpstar, we’re passionate about helping our clients utilize SCADA, PLC, and automation to their advantage. From the beginning of the design process to installation & maintenance, we’ll listen to your needs and shape your system accordingly.

Industrial automation control systems involve the integration of devices, machines, and equipment within the manufacturing plant. Industrial automation control systems also require hardware, software, and communication solutions that turn the data collected by the sensors into information that results in an automatic action. Because of the versatility of PLC, it is used in various places for automation. PLC systems are flexible and applicable to a wide variety of industries. Here are some applications of PLC technology:

Cement Manufacturing

Manufacturing cement involves mixing various raw materials in a kiln. The quality of these raw materials and their proportions significantly impact the quality of the final product. To ensure the use of the right quality and quantities of raw materials, the accuracy of data regarding such process variables is of the essence. The distributed control systems using PLC controls ball milling, shaft kiln and coal kiln. The PLC ensures accuracy of data to measure right quantity and quality of raw materials in cement manufacturing.

Glass industry

PLCs have been used in the glass industry for decades to control material ratios and to process production of large sheets of glass. The technology has been advancing over the years and this has created an increased demand for the PLC control mode for use in the glass industry. The production of glass is an elaborate and sophisticated process so the companies involved often use PLCs with the bus technology in its control mode. PLC is used in both analog and digital mode in the glass industry. Analog mode is used for data recording and digital mode for position and digital quality control.

Paper industry

In the paper industry, PLCs are used in various processes. These include controlling the machines that produce paper products at high speeds. For instance, a PLC controls and monitors the production of book pages or newspapers in offset web printing.

Medicine

PLCs are used in injection molding, corrugation machine control applications, silo feeding and coal-fire boiler systems in hospitals.

HVAC

All businesses have to manage heating, ventilating, and air conditioning (HVAC) system to maintain comfortable, safe, and healthy climates for employees. Within certain industries, HVAC specifications may have to fall within tight tolerances. For example, certain electronics facilities or medical labs may have very narrow temperature or humidity ranges that are acceptable for sensitive equipment. Often these applications use sensors that can send an alert as soon as acceptable limits are exceeded. A PLC system can then notify the maintenance team that an immediate repair is in order. This can prevent expensive damage of electronic equipment or spoilage of food, beverage, or medical products. Even in basic climate control applications, multiple PLCs can be tied together for easier building management in a centralized location.

Oil & Gas

Companies operating in the oil and gas industry often add well pad sites as part of their expansion plans. These systems use pumps, valves, and sensors to work effectively and efficiently. By developing a single, scalable PLC system that incorporates HMI, oil and gas companies can get a handle on all its well pads quickly and easily. PLCs on well pads allow the computer to accurately read inputs and share outputs for specific locations. Technicians can be efficiently sent out to the well pads that require repair, maintenance, or additional inspection without manually sorting through well pad data. Adding well pads is simple as the infrastructure and training already exists.
