Setting Method

Make the Master Control Communications Mode Setting in the IO-Link Device Configuration
Settings for each port with the IO-Link Master Unit Configuration Tool.
Related Parameters
Set the parameters to the following values from the IO-Link Master Unit Configuration Tool.
You can also set the parameters with communications instructions addressed to the IO-Link Master
Units. Refer to 3-2 IO-Link Master Unit Parameters on page 3-3 for objects to access.

Operations for Communications Modes of Connected Devices
The operations for the types of devices that are connected to ports in each communications mode are
given in the following table.
Communi-
cations
mode for
the port
IO-Link Operation is performed.
Mode
SIO (DI) The IO-Link devices operate in
Mode the Standard I/O Mode (SIO
Mode) with conventional con-
tact point input.
SIO (DO) No operation is performed.
Mode An error will not be detected.
Disable Port No operation is performed.
*1. To continue the IO-Link communications startup operation, the output from non-IO-Link actuators turns ON
and OFF in the internal signal data to establish IO-Link communications. Therefore, before you connect a
non-IO-Link actuator, make sure that the communications mode is already set to SIO (DO) Mode.
Precautions for Safe Use
Do not connect a non-IO-Link actuator to a port that is set to IO-Link Mode.
Depending on the operation to establish IO-Link communications, the actuator may unexpect-
edly and repeatedly turn ON and OFF in a short cycle.
