Question

Quizplus · Accepted Answer

PLC communications protocol is the standardized method used for transmitting data between different devices. This includes communication between PLCs and other devices such as HMIs and SCADA systems. PLC protocols are responsible for establishing rules for data transfer, ensuring reliability and accuracy of data, and providing a seamless flow of information between interconnected devices. While programming PLCs and connection of input/output devices are important aspects of PLC operation, they are not directly related to the communications protocol used for data transfer.
