Hello, I’m seeking assistance regarding backing up a PS4-341 Moeller CPU that lacks a memory card. It appears that backing up isn’t possible in my current situation. Additionally, I need help resolving a PLC error since the PLC is in boot mode, and I’m unable to upload a new program to the CPU. Could you please provide guidance on how to address this issue? Thank you!
