3 Calculate the number of input/output points.
Calculate the number of input/output points on the whole system.
1. Calculate the number of input/output points of the main unit and extension devices.
2. Calculate the number of remote I/O points on the network.
Since this system uses CC-Link, calculate the number of the remote I/O stations.
3. Calculate the total number of input/output occupied points (number of input/output points).
