- Save the project as a .cpr or .zip file
- Move the file to the new device and open it in CICON
How do I make a range of registers retentive (non-volatile)?
You can make M, L, C, S, and D registers non-volatile by adding the range to a Latch in the PLC Parameter section. For example, to retain D20–D4000, configure that range within the Latch settings.
