10-6-1 Maximum I/O Response Time
Output Data
*1 Pout_size: The larger of the total IO-Link output data sizes for IO-Link communications between ports 1 and 4
and ports 5 and 8.
*2 For information on how to determine the IO-Link communications cycle, refer to "10-6-2 Determining the
IO-Link Communications Cycle" in Page 10 - 20.
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
Slave output
response time
0.091 × Pout_size
*1
+ 0.001 × (Total size (in
bytes) of IO-Link process output data from
IO-Link communications from port 1 to port
8) + 3.04 + IO-Link communications cycle
*2
[ms]
0.091 × Pout_size
*1
+ 0.001 × (Total size (in
bytes) of IO-Link process output data from
IO-Link communications from port 1 to port
8) + 3.04 [ms]
Example: When the IO-Link output data
sizes of the IO-Link devices (actuators) for
port 1 through port 4 are all 2 bytes, the
IO-Link output data sizes of the IO-Link
devices (actuators) for port 5 through port 8
are all 4 bytes, and the IO-Link
communications cycle for those IO-Link
devices (actuators) is 2.1 [ms]: 0.091
× 4
bytes
× 4 devices + 0.001 × Total of 24
bytes + 3.04 + 2.1 = 6.62 [ms]
Example: When port 1 through port 7 are
used by IO-Link devices with an IO-Link
output data size of 2 bytes and port 8 is
used by a non-IO-Link device (actuator):
0.091
× 2 bytes × 4 devices + 0.001 × Tota l
of 14 bytes + 3.04 = 3.782 [ms]
