 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 EtherCAT Coupler Unit until preparations to update the output 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.
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 val-
ues of the items to make the calculation.
 Tnx-Indelay
This is the input delay time of the NX Unit. It is the time required to read the status of the input termi-
nals into NX Unit memory.
There is a unique value for each type of NX Unit. The NX Unit input delay time has a different defini-
tion or value for each type of NX Unit. The following table gives the value or definition of the input
delay time for each type of NX Unit.
If a formula rather than a value is given for Tnx-Indelay in the above table, refer to the user’s manu-
als for individual NX Units or to the
NX-series Data Reference Manual (Cat. No. W525) to make the
calculations.
 Tnx-Outdelay
This is the output delay time of the NX Unit. This is the time to change the output terminals accord-
ing 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 follow-
ing table gives the value or definition of the output delay time for each type of NX Unit.
