Using FW 2023.0 and PLCnext Engineer 2023.0.4, both AXC F 2152/3152, I seem to have an issue with saving the retain data after sending program changes. After stopping the runtime and a warm start, it works again. Is this a known issue or possibly something I am doing wrong?
To help investigate this problem:
What steps can we take to reproduce this issue?
What is the incorrect behaviour that we will see?
What is the expected (correct) behaviour?
For me, it seems to happen with every program/controller/configuration. Not to say that rules out being user error, but it is consistent.
1. Write and start project to PLC.
2. Save retain data via button in PLCnext Engineer cockpit. PLCnext Engineer shows message: "The retain data was backed up successfully. (MSG_PCW0002)".
3. Make some change to the program. Write and start project changes.
4. Attempt to save retain data again, but this time an error occurs. PLCnext Engineer shows message: "Cannot backup retain data. (MSG_PCW0004)".
5. Stop PLCnext runtime via PLCnext Engineer.
6. Warm start PLCnext runtime via PLCnext Engineer.
7. Save retain data via button in PLCnext Engineer cockpit. PLCnext Engineer shows message: "The retain data was backed up successfully. (MSG_PCW0002)".
If it would be helpful to have a copy of my program, email me to request a copy.
