A distributed control system or DCS is a control system in which the controller components are not local but are dispersed throughout the system with every component sub-system controlled by one or more controllers. The entire arrangement of controllers is associated by systems for correspondence and...
PCB design software creates the layouts for printed circuit boards. Electrical engineers use it regularly to not only create the design, but also to draw from previous PCB designs. The software allows you to route the electrical connectivity before it is then printed onto a chosen type of circui...
LIFO stands for last in first out. The meaning of this sequence can be understood easily from its name. The thing that comes last will go out first. You input one element; and when you request an element, the last one that is entered will be given to you. This samelogicworks in PLC ...
1.1 Key Substation Equipment Involved in Interlocking 1.1.1 Isolator (Disconnector) Definition:An isolator (or disconnector) is an off-load device, meaning it does not have the capability to break load current orfault current. Its primary function is to provide a visible physical break in the ci...
it tends to focus on more general applications. In contrast, IIoT technology is only used in industrial settings by professionals in an industrial field, meaning the market focus is smaller. Some of IIoT's main applications are in power plants, oil and gas refineries and manufacturing facilities...
The 2.4G frequency band is almost universally open and license-free, meaning that device manufacturers can develop products for global markets without worrying about spectrum restrictions in different countries or regions. Due to its higher frequency, the 2.4G band supports higher data transmission rate...
I referenced a legend in the P&ID video. Hopefully this will help clear that up a little bit. A legend simply put is a chart with all of the symbols used in an individual diagram. It could be a mechanical, P&ID, electrical symbol legend, or other types of diagram. This is an ...
Move Instruction Works on the BIT level The Move block only works on the bit level, meaning it moves the Bits representation of theINmemory area to theOUT1memory area, only the representation not the value inside. For example: ifINis01010101it will be moved toOUT1with the same representatio...
Power line communication (PLC): Uses electrical wiring to send data through the power lines in a building. Wi-Fi: Allows wireless Internet access in homes, offices, and public places like cafes. Bluetooth: Used for short-distance communication between devices, such as connecting smartphones to ...
Functional Units of SCADA Master Terminal Unit (MTU) MTU is the core of the SCADA system. It comprises a computer, a PLC, and a network server that helps the MTU communicate with the RTUs. MTU begins communication, collects and saves data, helps to interface with operators, and communicates...
