'ioTouch2 Lite' is a Lite edition of 'ioTouch2'. "ioTouch2" is an iPhone/iPod touch application which enables you to monitor and manipulate PLC(Programmable Logic Controller*1) devices easily, without the expert knowledge. *1 PLC - A digital computer used for control of machinery on factory assembly lines, etc. = The difference from 'ioTouch2 Pro' 'ioTouch2 Lite' has a restriction time (30 min. in a day) to communicate with real plc. There are Add-on items for each PLC provider. If you bought an item, it can connect to your selected provider's PLCs. More details to see http://iphone.itosoft.com/iotouch2/diff_pro_lite = What It Changes In general, there must be at least 2 people for checking I/O at the startup of a device; one for switch-on, another for monitoring. With ioTouch, you can do this by yourself, because you can monitor the device's change at the same time you are switching it, with iPhone/iPod touch in hand. Because full knowledge of PLC is not required to use ioTouch2, an assembler can adjust machines through ioTouch2. = Easy To Use A device's status appears as a lamp. You can manipulate it by pushing buttons. It's really easy to use. = How To Connect PLC devices ioTouch2 connects PLC devices(*2) by Wi-Fi, so that you can take it with you easily. If your PLC devices support Ethernet, you just need to build a Wi-Fi. Otherwise ioTouch2 can connect them through a Serial-Ethenet converter. "PLC Share" is no longer necessary. *2 ioTouch2 supports most of KEYENCE, MITSUBISHI, YOKOGAWA and OMRON devices. More details to see http://iphone.itosoft.com/iotouch2/spec . ===================================== --- C A U T I O N --- ioTouch2 can switch on/off devices. If you need to interlock devices controlled by PLC, you need to configure that on PLC. If there are some devices of which you are not sure about safety, please set the permission of them readonly and don't use that function. =====================================

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.
