I am a teacher in a technical school. I am using PLCnext PLC’s (AXC F 2152) in my lessons. The PLC’s are configured so that we don’t need the password to log in. We’ve given each PLC a different IP-address. When my students start up a new project, it often happens that the PLC loses his IP-address. Why does this happen, and how can I solve it?
Hi snitsig20,
I dunno how your students work with PLCnext but since you opened this thread in the PLCnext Engineer section of the forum I assume you work with it. Regarding your question why it happens, I’d say your students either reset the PLC to factory defaults or overwrite the PLCs settings with the project settings.
Reset to factory defaults:
Write project settings (name, IP, Subnet, Gateway) to the PLC:
In that case you could prepare projects for your students, that already contain the correct IP parameters, so they don’t have to meddle with those settings.
If you want them to create their own projects they should avoid the commands shown above and use:
Apply PLC settings to the project:
Project IP Settings:
Or the Ad-hoc IP address for the communication between workstation and PLC:
