(g) Calculating Tnx-Indelay
Tnx-Indelay of an NX-ID3343 Digital Input Unit is defined as the ON/OFF response time
plus the input filter time. The ON/OFF response time is 0.10
*1
s.
μ
*1. Calculation condition (5) says there is no filter, so the time is 0 μs.
Therefore the value of Tnx-Indelay for the NX-ID3343 Digital Input Unit is as follows:
Tnx-Indelay = 0.10
(h) Calculating Tnx-Outdelay
The Tnx-Outdelay of an NX-OD3153 Digital Output Unit is defined as the ON/OFF
response time. The ON/OFF response time is 0.30
Therefore the value of Tnx-Outdelay for the NX-OD3153 Digital Output Unit is as follows:
Tnx-Outdelay = 0.30
 Calculating the I/O Response Times
The I/O response times are as follows based on the calculation results for the elements.
Formula:
Maximum I/O response time
Formula:
Minimum I/O response time
