You can download and install Support software Wave Inspire HUB.

[Making design easy] Auto‑connect to devices from over 100 manufacturers Instantly usable sensor data

Just wire and power on to instantly monitor the status of various sensors. [Patent pending]*1

GD Series Features 2

OMRON’s unique easy connection function

Automatically searches, downloads, and assigns IODD files from over 100 manufacturers.

GD Series Features 4

*Note: Easy automatic connection requires an internet-connected PC and powered devices.

In such cases...

Want to start designing even though the IO-Link master unit or devices are not yet available

You can do it even without actual devices.

Unable to connect the PC to the internet during on-site commissioning

If you download the IODD files in advance to a specified folder on your PC, you can connect without any issues.

*1. “Patent pending” and “Patented” refer to patent status in Japan (as of January 2026).
*2. Estimated time under OMRON-specified conditions. Actual time may vary depending on the number of connected devices and internet environment.
*3. This service is provided by the IO-Link Community.

Automated Generation of "Address Comment Tables" for easy PLC Communication

Replace hours of manual reading and debugging with simple copy-and-paste.
You can easily see which IO-Link device’s process data is assigned to each address.

GD Series Features 9

Simple wiring without input units

Previously, ON/OFF signals and analog signals were transmitted using separate wiring and I/O units. Now, they can be consolidated into a single communication master unit. This simplified wiring reduces both design and wiring time.

GD Series Features 10

Easily obtain accurate data

Digital data transmission eliminates A/D and D/A conversion errors, removing the need for noise countermeasures and scaling. Data can be easily collected.

GD Series Features 11

[Making startup easy] No manual configuration required Quickly duplicate settings across multiple sensors

Copy the sensor settings with one click

GD Series Features 13

One‑click transfer of sensor and master unit settings

GD Series Features 14

Even sensors in hard-to-reach places can be configured from the support software

GD Series Features 15

Easy-to-use, unified setting menu

Previously, you had to remember the menu hierarchy and button layout for each sensor, but now you can operate all sensors with the same interface, regardless of sensor type or manufacturer.

GD Series Features 16

Automatic output of setting reports

The configured data can be output as a report. This makes it easy to compare and verify detection parameters and manage evidence at shipment, which previously required handwritten notes or Excel input.

GD Series Features 17

Set thresholds while viewing graphs.*1

Measurement values can be displayed as a time trend graph, allowing you to set thresholds while viewing the graph.

GD Series Features 18

*1. These will be supported in a future version upgrade.

[Making maintenance easy] Quick recovery in the event of trouble Prevent issues in advance by leveraging data

Backup sensor settings to the GD unit for each sensor – quick recovery with just replacement and startup

GD Series Features 21

In such cases...

Previously, it took a lot of time to recover from sensor failures.

GD Series Features 22

Easily identify and restore changed items [Patent pending]*1

You can compare the initial startup settings saved in the support software with the current sensor settings.
Any differences from normal conditions are immediately highlighted. If an unintended setting change is detected, it can be restored with a single click.

GD Series Features 23

Quickly identify causes during troubles

With the GD series, you can instantly identify errors or faulty sensors. You can immediately start recovery work, greatly reducing downtime.

GD Series Features 24

Take preventive measures before malfunctions

By managing not only ON/OFF signals but also numerical data such as sensor incident level with the support software, you can detect sensor contamination and build a predictive maintenance system.

GD Series Features 25

*1. “Patent pending” and “Patented” refer to patent status in Japan (as of January 2026).

Compact design supporting 16-channel connection IO-Link Master Unit GD Series

[Smallest in its class] Half the space compared to conventional models*1

Achieves approximately half the size (W110×D31.4×H63mm) of a typical 8-channel IO-Link master.
Furthermore, with double the number of channels (16ch), it contributes to space saving inside equipment.

GD Series Features 29

*1. Compared to the size of a typical 8-channel IO-Link master (according to OMRON investigation in January 2026).

Compatible with a wide range of field networks, easily connectable to familiar PLCs

IO-Link master unit lineup

GD Series Features 32

*2. These will be supported in a future version upgrade.

Display and operation panel usable even without a PC

GD Series Features 33

Not only IO-Link devices, but also mixed connection of NPN/PNP devices is possible

The type of I/O connection can be set for each port, allowing effective use of unused ports.

GD Series Features 34

OMRON IO-Link device

GD Series Features 35

Three features for safe and secure use

Locator function to identify pairing [ZP-L] [E3NX-FA] [K3CV]

When a command is sent from the support software, the indicator light on the connected device blinks, making it easy to identify which device is connected at a glance.

Key lock function that cannot be released by button operation [ZP-L] [E3NX-FA] [E3AS-HF]

Key lock can be enabled via IO-Link command, making it impossible to release by button operation.

GD Series Features 38

Smart verify function that notifies the PLC of setting changes [ZP-L] [E3NX-FA] [Patent pending]*1

The sensor outputs alarms for parameter changes and unintended setting modifications, enabling immediate detection of abnormalities.

GD Series Features 39
