• The maximum number of nodes can vary depending on the specific model and configuration of the PLC.

The scan cycle of a PLC refers to the time it takes for the PLC to complete one full cycle of scanning all inputs, executing the program logic, and updating outputs.

• The scan cycle consists of three main steps: input scan, program scan, and output scan.

• During the input scan, the PLC reads the state of all input devices connected to it.

• In the program scan, the PLC executes the user-defined program logic based on the inpu...read more
