10.1.2 Time required for each processing included in scan time
The I/O refresh time is the time for refreshing I/O data to/from the following modules
mounted on the main base unit and extension base units.
• Input module
• Output module
• Intelligent function module (special function module)
Calculation method
Use the following expression to calculate the I/O refresh time.
(I/O refresh time) = (number of input points/16)
16) N2
Refer to Table10.1 for N1 and N2.
