scanning time:
In general: scanning time: it is the time taken to read all inputs then execute the program and apply on outputs.
In PLC: it is only 1 processor check the previous procedures so its scan time depend on the quantity of data and program.
In DCS: There are several processors each processor has its inputs and outputs and its private program so each processor in DCS has its private scan time applied on each loop.

Galvanizing.
