NX-series IO-Link Master Unit


IO-Link makes sensor level information visible and solves the three major issues at manufacturing sites! The screwless clamping terminal block reduces wiring work.

Downtime can be reduced.

Notifies you of faulty parts and such phenomena in the Sensor in real time.

The frequency of sudden failure can be decreased.

Condition monitoring of sensors and equipment to prevent troubles.

The efficiency of changeover can be improved.

The batch check for individual sensor IDs significantly decreases commissioning time.

[Omron’s IO-Link Compliant Equipment] Masters and Sensors Can Be Chosen to Match Your Setup Situation

Omron provides two types of Masters, a Master Unit with screw-less clamp terminal blocks and a Master Unit for M12 Smartclick connectors, as IO-Link compliant devices and Sensors for connecting to the screw-less clamp terminals or to the M12 connector terminals that support each Master.

NX-ILM400 Features 4

[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

NX-ILM400 Features 5

Past 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...

NX-ILM400 Features 6

[With an IO-Link Photoelectric Sensor/Proximity 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.

NX-ILM400 Features 7

[To those in charge of maintenance “Condition monitoring” for predictive maintenance (1)] The Proximity Sensor Indicates an Excessive Proximity to the Sensing Object. Understand the Changes in Device Condition in Advance and Reduce Sudden Stops

NX-ILM400 Features 8

Existing problems

The detection position changes due to wear and vibration in the device’s mechanical parts and as a result, false detection and collision with the sensor have a negative impact on the device...

NX-ILM400 Features 9

[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 device.

NX-ILM400 Features 10

[To those in charge of maintenance “Condition monitoring” for predictive maintenance (2)] Understand Unstable Situations in the Incident Level of the Photoelectric Sensor in Advance and Reduce Sudden Stops

NX-ILM400 Features 11

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 device to stop...
∙ Water drops stick to the sensing surface of the reflective sensor causing reflected light to enter...

NX-ILM400 Features 12

[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.

NX-ILM400 Features 13

[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

NX-ILM400 Features 14

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...

NX-ILM400 Features 15

[With an IO-Link Photoelectric Sensor/Proximity 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.

NX-ILM400 Features 16

[Setup] Setting all sensors from a host device at the same time

Program all at once to reduce commissioning time and inconsistent settings

NX-ILM400 Features 17

[I/O check] Use identification checks with HMI to prevent installation mistakes

Makes it possible to check for sensor installation mistakes before commissioning
