This section describes the maximum I/O response time of the IO-Link Master Unit when the CPU Unit is
connected.
For information on timing charts and calculation methods for I/O response times for NX Units when con-
necting to the CPU Unit, refer to
Specifications and Basic Operation of Tasks for NX1P2 CPU Units
in
the
NJ/NX-series CPU Unit Software User’s Manual
(Cat. No. W501).
The following NX Unit parameters are necessary to calculate I/O response times.
• Tnx-InProc: Input data processing time of the NX Unit
• Tnx-Indelay: Input delay time of the NX Unit
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

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 ×

I/O data type

0.044 × (Total size (in bytes) of IO-Link pro-
cess output data from IO-Link communica-
tions 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
communications 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
