Time Required For Each Processing Included In Scan Time - Mitsubishi 00JCPU User Manual

10.1.2Time required for each processing included in scan time

This section describes how to calculate the processing and execution time described in Section 10.1.1.
(1) I/O refresh time
The I/O refresh time is time required 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
Calculation method
Use the following expression to calculate the I/O refresh time.
(I/O refresh time) = (number of input points/16)
For N1 and N2, refer to Table10.1.
