NXType of NX Unit Tnx-Indelay Remarks
Digital Input Units ON/OFF response time + Input
filter time The ON/OFF response time depends on the model of
the Unit.
You can set the input filter time for each Unit.
Analog Input Units Conversion time × Number of
points The conversion time and number of points depend on
the model of the Unit.
Refer to the user’s manuals for individual NX Units or to the NX-series Data Reference Manual
(Cat.No. W525) for the definition of Tnx-Indelay in the above table and use it in the calculations.
l
Tnx-OutProc
This is the output data processing time of the NX Unit. It is the time from when the NX Unit reads
the output data that was sent by the EtherNet/IP Coupler Unit until preparations to update the out-
put data are completed. There is a unique value for each type of NX Unit.
The NX Unit output data processing time has a different definition or value for each type of NX Unit.
The following table gives the value or definition of Tnx-OutProc for each type of NX Unit.
Type of NX Unit Tnx-OutProc Remarks
Digital Output Units 0 μs ---
Analog Output Units Conversion time × Number of
points
The conversion time and number of points depend
on the model of the Unit.
If a formula rather than a value is given for Tnx-OutProc in the above table, refer to the user’s man-
uals for individual NX Units or to the
NX-series Data Reference Manual (Cat. No. W525) for the
values of the items to make the calculation.
l
Tnx-Outdelay
This is the output delay time of the NX Unit. This is the time required to change the output terminals
according to the updated output data in the NX Unit. There is a unique value for each type of NX
Unit.
The NX Unit output delay time has a different definition or value for each type of NX Unit. The fol-
lowing table gives the value or definition of the output delay time for each type of NX Unit.
Type of NX Unit Tnx-Outdelay Remarks
Digital Output Units ON/OFF response time The ON/OFF response time depends on the model of the Unit.
Analog Output Units 0 μs ---
If a formula rather than a value is given for Tnx-Outdelay in the above table, refer to the user’s
manuals for individual NX Units or to the
NX-series Data Reference Manual (Cat. No. W525) for
the values of the items to make the calculation.
Additional Information
To calculate the I/O response times between a Safety I/O Unit and a standard I/O Unit, add the
input response time or output response time to the FSoE watchdog timer value of the Safety I/O
Unit.
