YINGD Posted October 8, 2014 Report Posted October 8, 2014 I need to come up with a panel design that use a Unistream HMI but can be used in a hazardous area. The Area could be C1 or C2 and D1 or D2. Since the Unistream HMI is only rated for use in a NEMA 4/4X area, I would need to put a window over the HMI. The problem then is that the operator cannot touch the screen. I need to find a way to select items on teh screen without touching the screen. I am hoping that there is a way I could use a joystick or mouse to be able to control a cursor on the screen and then click where needed. Is there a way to do this? If not, are there any plans to impliment mouse or joystick control on the HMI?
ahoover Posted October 8, 2014 Report Posted October 8, 2014 I have found that it works to plug a USB mouse into one of the USB ports on the UniStream. A message will come on the display asking to do a reset, after that a mouse pointer appears & you can click on HMI elements similar to touching them. In one of my applications, I use the "System>General>Touched Bit" & "System>General>Coordinate X/Coordinate Y" values(for detecting location of a touch on HMI). Unfortunately, a mouse click does not activate these values, but otherwise it is a really neat feature. 1
John Anastasiades Posted October 8, 2014 Report Posted October 8, 2014 Y. INDS, Ahoover is correct, it is possible to plug a mouse into the unit via the USB Hosts on the side of the panel. If the unit is powered before a mouse is plugged in, you will receive a prompt that alerts the mouse has been detected. This prompt will provide two options, either "Reset Display" or "Postpone." The mouse will not be available until the display is reset.
s.pratt Posted October 15, 2014 Report Posted October 15, 2014 rcerva, The mouse driver feature is not included with the V570. This feature is only included with the UniStream USB host ports. They have a standard keyboard and mouse driver already installed to them.
