Although FPGA and CPLD are both programmable ASIC devices and have many common features, they have their own characteristics due to the differences in the structure of CPLD and FPGA: ① CPLD is more suitable for completing various algorithms and combinational logic, and FPGA is more suitable for...
A complex programmable logic device is an innovative product compared to earlier logic devices like programmable logic arrays (PLAs) and Programmable Array Logic (PAL). The earlier logic devices were not programmable, so the logic was built by combining multiple logic chips together. A CPLD has a...
Programmable logic controllers automate industrial processes such as robotic devices. What is a safety programmable logic controller? A safety programmable logic controller (safety PLC) is a type of PLC that is customized for critical safety applications in industrial environments. A safety PLC has all...
Processor– This is the central processing unit or “brain” containing the main memory, arithmetic logic unit (ALU), control unit, and instruction set to execute the PLC program. PowerSupply– Provides regulated DC power to the PLC processor, I/O modules, and field devices. Usually 24VDC. ...

PLC (Programmable Logic Controller) has many features similar to our personal computer at home. They both have a power supply unit, a CPU (Central Processing Unit), Inputs & Outputs (I/O) ports, RAM and ROM memory, and control software. The biggest difference between the two is PLC can...
If actual value is too low, the controller increases its output to correct it. The gain that such a controller has is called a proportional gain. If the gain is, for instance, ten times - then the output is ten times the difference. The proportional gain gets a shorter name "P".The ...
PLC stands forProgrammable Logic Controller. Some people also refer to them as industrial computers. What does a PLC do? A PLC on a simple level uses logic to convert an input into a set output. This is much like a computer turns you pushing a button on your keyboard (input) into a ...
The article focuses on innovations related to the combination of microprocessors and programming logic design. It is mentioned that the combination of these two will lead to the designing of a truly programmable reconfigurable...
What Is an FPGA? Field-Programmable Gate Arrays (FPGAs) are semiconductor devices that are based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnects. Unlike traditional integrated circuits (ICs) - for example,CPUsorGPUs- which have a fixed function once ...
