About

I/O Field

Features
Read full description

The “WAGO I/O Field” app is for monitoring and full operation of the WAGO I/O System Field. This app allows you to display device information for both fieldbus modules and IO-Link hubs, make settings and adjust all device parameters. The communication this requires takes place through the Bluetooth® interface of the mobile device once Data Matrix has been scanned to select the device. Users and the associated access rights can be set up and managed. Outputs can be forced and inputs set in order to support commissioning of systems. The current measured values of a port can be displayed (temperature, voltage, current and states) and configured (including operating mode and filters). Devices can be reset to the factory settings and firmware restarted. License Agreement By downloading the app, you agree to the terms of the WAGO’s license agreement (accessible via EULA and the support URL below).
