Function Specification

Function Description
Communications Cyclic
communications
I/O data (process data) in the IO-Link devices is cyclically exchanged with the IO-Link Master Unit as the IO-Link communications master.
At the same time, this data and the status of the IO-Link Master Unit is cyclically exchanged with the controller, with the IO-Link Master Unit operating as a slave of the controller.
Cyclic communications can be used to check the amount of detection performance deterioration in devices, and to check changes in usage conditions, such as the amount of incident light for photoelectric sensors, stability detection margins, and excessive proximity for proximity sensors.
Message
communications
The controller can send messages (commands) to the IO-Link Master Unit and receive the response from the IO-Link Master Unit.
The IO-Link Master Unit can also function as a gateway to send messages (commands and responses) between the controller and the IO-Link devices.
During operation, you can change and adjust device parameters, such as threshold settings, tuning execution, and ON-delay time changes, from a program.
Or, during operation, you can check the internal status, such as the operating times of devices.
Communications mode settings You can select any of the following modes for each port:
IO-Link Mode, SIO (DI) Mode, SIO (DO) Mode, and Disable Port
This allows you to combine IO-Link communications and digital I/O in a single unit.
Digital inputs for pin 2 In IO-Link Mode, you can perform digital input with pin 2 while performing IO-Link communications.
Automatic baud rate setting for
IO-Link communications
The IO-Link Master Unit automatically matches the specific baud rates (COM1, COM2, or COM3) of the IO-Link devices to communicate with the IO-Link devices.
Therefore, it is not necessary to set the baud rate of the connected device for each port.
Connected device verification This function is used to verify the configuration of IO-Link devices that are connected to the IO-Link Master Unit against the registered IO-Link device configuration settings when the power supply is turned ON.
The user can enable or disable connected device verification.
IO-Link communications error
detection
This function detects I/O cable breaks, disconnections from IO-Link device ports, error-level device events, device configuration verification errors, and IO-Link device malfunctions.
Detection of short-circuits in I/O
cables
This function detects short-circuits in I/O cables
Notification of input data validity The controller can use the Input Data Enabled Flags to determine whether the process input data for IO-Link communications is valid.
Load rejection for controller
communications error
This function turns OFF outputs from the IO-Link Master Unit when a communications error occurs in communications with the controller in IO-Link Mode or in an SIO mode.
This prevents incorrect output operations when communications error occurs.
IO-Link total communications lost
frames
The IO-Link total communications lost frames can be read from the CX-ConfiguratorFDT.
You can use this function to determine communications status as affected by I/O cable noise or other factors.
Digital input filter This function is used to eliminate chattering and noise of the input signal for digital inputs in SIO(DI) Mode or for digital inputs for pin 2 in IO-Link Mode. It prevents data change and stabilizes the input signal even in situations where the input data changes due to chattering or noise and the bit status is unstable.
Digital input collection* In IO-Link Mode, this function reflects the specified bit data in the input data from the IO-Link device on the digital input data of the IO-Link Master Unit. As a result, the bit data in the input data from the IO-Link device can be aggregated into the digital input data of the IO-Link Master Unit. One bit for each IO-Link port can be aggregated. This function cannot be used in SIO (DI) Mode and SIO (DO) Mode.
If you use this function, digital inputs with pin 2 cannot be used.
Backup and restoration of
parameter settings in IO-Link
devices
This function is used to back up parameter settings in IO-Link devices in the IO-Link Master Unit or restore them to IO-Link devices.
This eliminates the need to set parameters again after replacing an IO-Link device.
Event log This function records events, such as errors and status changes, that occur in the IO-Link Master Unit and the IO-Link devices.

* This function is supported with the unit version 1.1 or later.
