 Output Data
This section describes the maximum I/O response time when an EtherNet/IP Coupler Unit is con-
nected.
For information on timing charts and calculation methods for I/O response times for NX Units in Ether-
net/IP Slave Terminals, refer to
I/O Response Times in the NX-series EtherNet/IP Coupler Unit User's
Manual (Cat. No. W536).
The following NX Unit parameters are necessary to calculate I/O response times.
• Tin: Input response time of the NX Unit
• Tout: Output response time of the NX Unit
The parameter values and calculation methods for the IO-Link Master Unit are given below.
I/O data type
IO-Link process output data from IO-Link
communications in IO-Link Mode
Digital output data in SIO (DO) Mode
Parameter
Tnx-OutProc
0[ms]
Tnx-Outdelay
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 + IO-Link
communications cycle
*1
[ms]
*1. For information on how to determine the IO-Link communications cycle, refer to 5-3-4 Determining the IO-Link
Communications Cycle on page 5-11.
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
[ms]
