(d) Calculating Tmax-OutTrans
There is only one EtherCAT Slave Terminal, so the value is as follows:
Tmax-OutTrans = T#1-OutTrans
The following parameters are required to calculate T#1-OutTrans.
Total byte size of the out-
put data of the NX Unit
Number of NX Units
Number of NX Units with
BOOL output data
Refer to Unit Configuration and Data Sizes in the EtherCAT Slave Terminal on page 12-10
for the values of the above parameters.
Therefore, the value of Tmax-OutTrans is as follows:
Formula: Tmax-OutTrans = T#1-OutTrans
(e) Calculating Tmax-InProc
Tnx-InProc for an NX-ID3343 Digital Input Unit and an NX-AD4608 Analog Input Unit is 0
μs.
Therefore, the value of Tmax-InProc is as follows:
Formula: Tmax-InProc = 0.00
(f) Calculating Tmax-OutProc
Tnx-OutProc of an NX-OD3153 Digital Output Unit is 0 μs.
Tnx-OutProc of an NX-DA3605 Analog Output Unit is defined as the conversion time times
the number of points. The conversion time is 10 μs per point and there are 4 points.
Therefore, the value of Tmax-OutProc is as follows:
Formula: Tmax-OutProc = Conversion time × Number of points = 10 × 4 points = 40.00

= 11.71 × (Integer quotient of total byte size of the output data of the NX Unit ÷32)
+ 0.46 × (Remainder of total byte size of the output data of the NX Unit ÷32)
+ (0.19 × Number of NX Units with BOOL output data + 2.93)
+ 0.38 × Number of NX Units
+ 0.014 × Total bytes size of NX Unit output data
+ 30.40
= 11.71 × (Integer quotient of 12 bytes ÷32) + 0.46 × (Remainder of 12 bytes ÷32)
+ (0.19 × 8 Units + 2.93) + 0.38 × 18 Units + 0.014 × 12 bytes + 30.40
= 11.71 × 0.00 + 0.46 × 12.00 + (0.19 × 8 Units + 2.93)
+ 0.38 × 18 Units + 0.014 × 12 bytes + 30.40
= 47.38
Remarks
This is the total output data size of the NX Unit.
