 Tmax-InProc
This is the longest input data processing time of all of the NX Units in all of the EtherCAT Slave Ter-
minals in the same EtherCAT network.
The input data processing time of an NX Unit (Tnx-InProc) is the time from reading the status of the
NX Unit input terminals into memory until preparations to pass the read data to the EtherCAT Cou-
pler Unit are completed. There is a unique value for each type of NX Unit. With synchronous I/O
refreshing, this is the time from the NX Unit input synchronization timing until preparations to pass
the data are completed. The NX Unit input synchronization timing is when all of the NX Units that
use synchronous input refreshing in all of the EtherCAT Slave Terminals on the same EtherCAT net-
work simultaneously read the input data.
The NX Unit input data processing time (Tnx-InProc) depends on the NX Unit.
The following table gives Tnx-InProc for each type of NX Unit.

 Tmax-OutProc
This is the longest output data processing time of all of the NX Units in all of the EtherCAT Slave Ter-
minals in the same EtherCAT network.
The output data processing time of an NX Unit (Tnx-OutProc) 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. With synchronous I/O
refreshing, each NX Unit completes processing before the NX Unit output synchronization timing.
The NX Unit output synchronization timing is when all of the NX Units that use synchronous output
refreshing in all of the EtherCAT Slave Terminals on the same EtherCAT network simultaneously
update the output data.
The NX Unit output data processing time (Tnx-OutProc) 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 Units
Digital Output Units
Analog Output Units
Pulse Output Units
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.
