Failed to load program with error on PLCnextBaseServices

After a good build, i can’t get the program to load to the plc. But the basic library is updated to support the v25 FW
PLC FW 2025.6 - 25.6.0.41
PLC Next engineer 2025.0.3
PLCnextBase 1.7.2
ReSyBasic_V3010
ReSyBasic_V3001_Lib

Hi AMWaninge,
The error message indicates that a deprecated library is being referenced. (“Deprecated” means the library is outdated and no longer recommended for use.) The message also mentions compatibility with versions 2019 and 2024.6, which suggests that:

  • Something may not have been updated correctly, or
  • There’s a lingering reference to an older version still present in the system.
  1. To resolve this, please:
    Remove all existing versions of the PLCnext Base, including the currently installed one.
  2. Ensure no residual files or references remain, this includes checking inside other libraries that may still contain older PLCnext Base components.
  3. Install the latest version**** of the PLCnext Base and its associated libraries to ensure full compatibility.

This should eliminate the deprecated references and prevent version conflicts going forward.
Let me know if you need help identifying or cleaning up any leftover components.

Best regards,

I think it is the lingering reference to an older library. But have no clue yet to get it to work. deleted the old libraries from the library foder.
PLCnextBase 1.7.2 is the latest version in the store and installed it.
I allso deleted the old binaries folder befor a new rebuild.

You could also remove the .so file on the PLC manually, maybe it’s a fragment of an older project.

The PLC does not allow to manually delete the .so file via a FTP Client

Does plc fw in project configuration is 2025.x aslo?
To enable root login you have to set root password and enable root login via ssh.

And edit /etc/ssh/sshd_config file

And reboot plc or restart sshd service.
