11.1.2 Time required for each processing included in scan time
The scan time is the sum of the processings and execution times shown in Section 11.1.1.
This section explains how to calculate the processing and execution times shown in
Section 11.1.1.
(1) I/O refresh 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)
Note1
Calculation method
Use the following expression to calculate the I/O refresh time.
(I/O refresh time) = (number of input points/16) N1 + (number of output points/
16)
N2
Refer to Table11.1 for N1 and N2.
