The PLC I/O capacity of the distributed control system of several hydro power stations of a major generating company was assessed. The assessment included determining the number of used and spare I/O, studying the past I/O usage and estimating the number of I/O that would be required over the following 6 years, identifying and costing options to provide additional capacity (if required), and recommendation of a preferred option.
