[To those in charge of maintenance “Condition monitoring” for predictive maintenance (1)] Reduction of Sudden Stops by Grasping the Flow Rate Simultaneously with the Temperature of Cooling Water and Hydraulic Oil Circulating in Equipment
Existing problems
While the presence or absence of cooling water is checked by means of the ON/OFF-based pressure sensor, it is unable to detect any drop in the flow rate of the cooling water or any rise in the cooling water temperature. For that reason,
∙ The transformer is not cooled, and gets overheated, potentially leading to sudden stops of the equipment and the entire line.
∙ The tip may be deformed, causing defective products.
With an IO-Link IoT Flow Sensor
The flow rate and simultaneously the temperature of the circulation system are measured, substantially reducing sudden error.
Simultaneous monitoring of the flow rate and temperature changes, and informing of those changes, enable you to carry out predictive maintenance and reduce defective products.
[To those in charge of maintenance “Condition monitoring” for predictive maintenance (2)] The Proximity Sensor Indicates an Excessive Proximity to the Sensing Object. Understand the Changes in Equipment Condition in Advance and Reduce Sudden Stops
Existing problems
The detection position changes due to wear and vibration in the equipment’s mechanical parts and as a result, false detection and collision with the sensor have a negative impact on the equipment…
With an IO-Link Proximity Sensor
You are notified of excessive remoteness or proximity, and the occurrence of sudden defects is greatly reduced
Constantly monitoring the position of the sensing object and notifying of excessive remoteness or proximity can be used for predictive maintenance of the equipment.
[To those in charge of maintenance “Condition monitoring” for predictive maintenance (3)] Understand Unstable Situations in the Incident Level of the Photoelectric Sensor in Advance and Reduce Sudden Stops
Existing problems
∙ In a conveyance process operating for 24 hours, dust or dirt accumulated on the detection surface of the photoelectric sensor, leading to a decline in the light incident level that causes the sensor to make false detection and the equipment to stop…
∙ Water drops stick to the sensing surface of the reflective sensor causing reflected light to enter…
With an IO-Link Photoelectric Sensor
A light incident level monitor prevents false detection
With a response time of 1 ms, Photoelectric Sensor’s light incident level is output for monitoring. It is output when the light incident level exceeds the instability detection threshold, so you can check the site before false detection occurs and perform predictive maintenance.
[To those in charge of maintenance “Abnormality detection” for the shortest recovery] Detects Wiring Cable Disconnections and Errors and Improves Equipment Operation Rate Through Quick Maintenance
Existing problems
∙ An abnormality was displayed on the abnormality display screen, but upon going to look at the equipment, no external error was detected and the cause of the stop was not understood…
∙ Those responsible for maintenance investigated the cause of the abnormality from the activity of the stopped equipment, but because the maintenance person relied on the skill he or she has to identify the abnormality and replace the failed sensor, stoppages from 2 hours to several days occur…
With an IO-Link Sensor
Abnormal area and phenomenon of sensors are reported in real time
When an abnormality occurs in a sensor, because you can see where the abnormality occurred and the factors estimated for it, you can go to where the abnormality occurred and recover the equipment in the shortest amount of time.
Also with wire disconnection detection, not only output wires, but also power lines can be detected unconditionally.
Easy replacement of IO-Link sensors with Non-IO-Link sensors
You need a quick recovery but you have only Non-IO-Link sensors with no IO-Link sensors in stock. You probably think in such a case, the control program needs modifications, and requires additional time for the recovery.
With IO-Link Master, since the IO-Link ON/OFF data and the data for Non-IO-Link sensors are located in the same memory, replacement with Non-IO-Link sensors can be carried out without any modification of the control program, resulting in a reduction of the equipment downtime.
[To those in charge of production engineering “Individual identification” for the reduction of man-hours] Improving System Commissioning and Changeover Efficiency by Checking Identifications in Batches
Existing problems
∙ During system start-up or changeover, operators had to perform the I/O check for each of the thousands of sensors installed on the line, and it took an enormous amount of time…
∙ When a sensor is installed wrong or an error occurs, wasteful work occurred that would normally be unnecessary…
With an IO-Link Sensor
Without going to the site, you can check individual sensor identifications in batches, resulting in a sharp reduction of commissioning time
By checking the sensor identification (manufacturer/sensor type/model number), you can easily check mistakes such as misconnected or unconnected sensors and installation mistakes.
Also, because it is possible to program multiple sensors at once using the command language used only for the controller, it is also possible to reduce commissioning time sharply.

Function Specifications
| 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 enables partial troubleshooting for NJ/NX-series Controllers and NY-series Industrial PCs. |
|
* This function is supported with the unit version 1.1 or later.
