I'm using a unitronics plc unistream usp-070-b10 , second hand and there is a program on it which i do not need. mini USB to USB won't work for me so i tried Ethernet and I cant access UniApps when i hold down the top right hand corner, it prompts password and I don't no what it is.
Is there any way of rebooting the PLC & HMI back to factory settings so I can get into UniApps to get the IP address as the guys before hand changed the IP address.
