## What is ioTouch2 Pro?

"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. 

*** There is the Lite edition(Free); Try it first. ***

= 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.
