Swervomotor Posted March 20, 2019 Report Share Posted March 20, 2019 Why does Unilogic force me to update the firmware on the PLC even to just upload from the PLC? I'm trying to make a small change (ethernet IP scanner IP addresses) and when I try to open older version of unilogic it won't let me create a blank program to be able to go "online" and upload. So I go to newer version of Unilogic and create a blank program try to go "online" an it tells me I need to update the firmware on the PLC. So now I have to: 1. download the latest version of Unilogic onto a laptop 2. go find the PLC on the factory floor 3. OPEN THE CABINET 4. Connect USB drive or cable 5. Update Firmware 6. Hope the firmware update doesn't wipe the existing "upload" file Has anyone ever considered backwards compatibility??? This program was created less than 7 months ago.
