Scan time is usually the process cycle time taken by the plc for reading the status of inputs , evaluating the control logic and then updating the outputs.
This is a continous sequential process as the PLC is constantly assesing the input and changing the output based on the contorl logic.
Scan time of plc is about 0.1 ms to 10 ms.
