Three types of sensing methods and three types of connection methods are available.

[To those in charge of maintenance “Condition monitoring” for predictive maintenance] Reduction of Sudden Stops by Grasping the Flow Rate Simultaneously with the Temperature of Cooling Water and Hydraulic Oil Circulating in Equipment

E3Z-[]-IL[] Features 5

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.

E3Z-[]-IL[] Features 6

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] The Proximity Sensor Indicates an Excessive Proximity to the Sensing Object. Understand the Changes in Equipment Condition in Advance and Reduce Sudden Stops

E3Z-[]-IL[] Features 9

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...

E3Z-[]-IL[] Features 10

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] Understand Unstable Situations in the Incident Level of the Photoelectric Sensor in Advance and Reduce Sudden Stops

E3Z-[]-IL[] Features 13

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...

E3Z-[]-IL[] Features 14

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.

E3Z-[]-IL[] Features 16

[To those in charge of maintenance “Condition monitoring” for predictive maintenance] Incident Light Level Monitoring Minimizes Machine Downtime

E3Z-[]-IL[] Features 17

Existing problems

When a light curtain is installed in a harsh environment, its optical surface gets dirt easily.
It is hard to notice the light intensity drop until the machine stops...

E3Z-[]-IL[] Features 18

With an IO-Link Safety Light Curtain

Incident light levels are monitored to warn of low light intensity

Incident light levels of light curtains are monitored to provide advance warning of light intensity drops due to dirt or other factors, preventing false detection by light curtains.

E3Z-[]-IL[] Features 20

Use for scan monitoring

Monitoring incident light levels of all beams of the light curtain enables workpiece shapes to be detected, which helps identify workpieces.

E3Z-[]-IL[] Features 21

[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

E3Z-[]-IL[] Features 22

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...

E3Z-[]-IL[] Features 23

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.

E3Z-[]-IL[] Features 25

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.

E3Z-[]-IL[] Features 26

[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

E3Z-[]-IL[] Features 27

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...

E3Z-[]-IL[] Features 28

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.

E3Z-[]-IL[] Features 30

[To software designers and production engineers] Reduce Time to Design, Set up, and Maintain IO-Link Systems

E3Z-[]-IL[] Features 31

Existing problems

∙ IO-Link increases possibilities, but it takes time to make many settings and check that all settings are made correctly.

∙ It takes a great deal of effort to enter settings while reading the manual or instruction sheet.

∙ Time-consuming system changes don’t lead to improvement in uptime.

E3Z-[]-IL[] Features 32

With Omron’s IO-Link

Automatic parameter setting and automatic device variable generation reduce configuration time

Just select and place a device on the integrated development environment Sysmac Studio to automatically set all parameters at once and automatically generate device variables on the I/O map.
This reduces configuration time by 90% or more compared to our conventional IO-Link systems and also reduces omission of setting.

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

For the connection of IO-Link Sensors and IO-Link Masters, two types are available: a screw-less clamp terminal block and an M12 connector.
In addition, NX-ILM400 IO-Link Master with screw-less clamp terminal block is connectable not only to EtherCAT, but also to EtherNet/IP communication coupler units, and you can choose between them according to the system configuration.
