Thank You for answer, but I'm afraid You understood me wrongly. I mean a software loading like PLC booting with image on SD card or USB flash without using a computer as an initiator of software update. I mean this feature must be useful for screenless controllers working locally. I suspect I want too much....
My question about UniStream controllers without HMI. Is it possible to update software from SD card or USB flash without a command from computer utilities? Another words, can service specialist update software with only USB flash or sd-card locally?
