Please describe how PLC works?
before plc signal first from the external device. Continue to put on cpu. after receiving a processing signal according to a preset program.
PLC receives the input signal from push buttons, switches, sensors, and feeds it to the central processor cpu. And control output such as lights, motors ...
A signal from peripheral devices such as sensors, contacts, ... is put into the CPU input for processing after the processing is completed, the CPU will output and output to lateral controlled devices. out according to the program I have available
PLC receives signals from connected input devices and processes data and activates the output based on previously programmed numbers.
Please describe how PLC works?
The PLC executes the program in a loop order. Each loop is called a scan loop. Each scan cycle begins with a data transfer phase from digital input ports to the input virtual buffer area, followed by program execution phase.
We enter the request data into the PLC. The data is then encoded at the CPU and output to the device control.
PLC receives the input signal from push buttons, switches, sensors, and feeds it to the central processor cpu, it control output such as lights, motors
We conected PLC inputs/outputs with necessary equipments. Read input conected. CPU of PLC start executing the program and Run it, and display the results in the output

The PLC takes input signals from devices such as push buttons, switches, sensors and sends that signal to the central processor CPU. And control outputs such as lights, motors, bells ...
PLC will check input signals first. Next, based in the installed program the PLC will output the output signals accordingly. This will be repeated to get the corresponding output to the input is changed.
when the device is activated. the programmable controller will continuously repeat the user preset program and wait for the signals to appear on the input and output the output signal
PLC controller works by scanning the states on the output and the input. When there is a change in the input, the output will change accordingly
Plc has one input takes the digital signal and converts it to a logic signal. The output converts control commands from the CPU to control different devices.
The signals from peripheral devices are send to the cpu through the input module.the CPU will process and send it to output module to control the device according to the program.
PLC will check the input signal first. It will then output the corresponding output signal thanks to the PLC program installed earlier. This will be repeated to get the output corresponding to the changed input.
PLC based on input signals and algorithms controls inside written by the grogram it with output signals to control other devicer
PLC is the control logic can be driver set-up and is called a controller set-up
PLC receives information from the sensor, presses a button and another device end is already set. The PLC operations will be controlled by the CPU.
A PLC, also known as (Programmable Logic Controller), takes input signals from devices such as buttons, switches, and sensors and sends that signal to the central processing CPU. And then take out the processed parts such as lights, .....
