NX-series IO-Link Master Unit User’s Manual (W567)
• Tnx-OutProc: Output data processing time of the NX Unit
• Tnx-Outdelay: Output delay time of the NX Unit
The parameter values and calculation methods for the IO-Link Master Unit are given below.
Input Data
Output Data
I/O data type
IO-Link process input data
from IO-Link communica-
tions in IO-Link Mode
Digital input data for pin 2
in IO-Link Mode
Digital input data in SIO
(DI) Mode
Parameter
Tnx-InProc

0.072 × (Total size (in bytes) of IO-Link process input data
from IO-Link communications from port 1 to port 4) + 2.61+
Input filter time [ms]
Example: When port 1
through port 4 are all used
by IO-Link devices (sensors)
with an IO-Link input data
size of 2 bytes, and the
IO-Link communications
cycle for those IO-Link
devices (sensors) is 2.1
[ms]: 0.072 × 2 bytes × 4
d 2.61 + 2.1 = 5.286
[ms]
Example: When port 1
through port 4 are all used
by IO-Link devices (sensors)
with an IO-Link input data
size of 2 bytes and no input
filter is used: 0.072 × 2 bytes
× 4 d 2.61 = 3.186
[ms]
Example: When port 1
through port 3 are used by
IO-Link devices with an
IO-Link input data size of 2
bytes and port 4 is used by a
non-IO-Link device with no
input filter: 0.072 × 2 bytes ×
3 d 2.61 = 3.042
[ms]
I/O data type
IO-Link process output
data from IO-Link commu-
nications in IO-Link Mode
Digital output data in SIO (DO) Mode
Parameter
Tnx-OutProc

5-3-4 Determining the IO-Link
Communications Cycle
on page 5-11.
0.044 × (Total size (in bytes) of IO-Link process output data
from IO-Link communications from port 1 to port 4) + 1.47
[ms]
Example: When only port 4
is used by an IO-Link device
(actuator) with an IO-Link
output data size of 2 bytes,
and the IO-Link communica-
tions cycle for that IO-Link
device (actuator) is 2.1 [ms]:
0.044 × 2 bytes × 1
1.47 + 2.1 = 3.658 [ms]
Example: When port 1 through port 3 are used by IO-Link
devices with an IO-Link input data size of 2 bytes and port 4
is used by a non-IO-Link actuator: 0 + 1.47 = 1.47 [ms]
