Therefore, the value of T#1-Free_I/OCycle is as follows:
(f) Calculating Tnx-InProc
Tnx-InProc of an NX-ID3343 Digital Input Unit is 0 μs.
Therefore the value of Tnx-InProc for the NX-ID3343 Digital Input Unit is as follows:
(g) Calculating Tnx-OutProc
Tnx-OutProc of an NX-OD3153 Digital Output Unit is 0 μs.
Therefore the value of Tnx-OutProc for the NX-OD3153 Digital Output Unit is as follows:
(h) 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 μs and the input filter time is 0
μs.
*1
*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:
(i) 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 s.
Therefore the value of Tnx-Outdelay for the NX-OD3153 Digital Output Unit is as follows:
Formula: T#n-Free_I/OCycle = T#n-InTrans + T#n-OutTrans + T#n-exsoft
= 156.12 + 47.38 + 176.14
= 379.64
