It also seems to use for the education of PLC. ===================================== = Manipulation You can switch on/off bit devices with buttons and change values of word devices with slider controls. = Monitor With irPanel you can monitor conditions, warnings and alarms of machineries. = Editing Of Manipulation Panales And Monitors You can add or change manipulation panels and monitors in irPanel, without any special editor application. Because we have some patterns for manipulation panels which contain 1-10 buttons and 0-2 slider controls, you just need to choose what you like, then set a title and devices for it. To create a monitor view, just register both start point and end point of the target range of devices. = Connection irPanel connects PLC via wireless LAN so that you can take irPanel with you. If your PLC supports Ethernet, you only need to have wireless LAN. Otherwise ioTouch2 can connect them through a Serial-Ethenet converter. "PLC Share" is no longer necessary. * irPanel supports most of KEYENCE, MITSUBISHI, YOKOGAWA and OMRON PLCs. More details to see http://iphone.itosoft.com/irpanel/spec . ===================================== --- C A U T I O N --- irPanel 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. =====================================
