2 Built-in I/O
 Maximum I/O Response Time
The I/O response time is maximum when the input values change immediately after the CPU Unit
executes I/O refreshing.
The response time at this time can be calculated as follows.
Maximum I/O response time = Input ON/OFF response time + Input filter time + Task period x 3 +
Output ON/OFF response time
Primary periodic task:
Input terminal status:
Read input values:
Input device variables:
Output device variables:
Output terminal status:
Additional Information
The input ON/OFF response time and the output ON/OFF response time vary depending on
the terminal that is used.
Refer to the NX-series NX1P2 CPU Unit Hardware User's Manual (Cat. No. W578) for the
specifications of each terminal.
