I’m having some difficulties with the 2025 version of PLCNext Engineer. I have a laptop on a location that does not have internet that runs this version. The PLCs at that location are on a 2023 firmware. It looks like the Modbus TCP 15 library that I’m using is not compatible with the 2025 version as it was with 2024. I get error code SEM1190 on functions like TLS_SOCKET_2. I am unable to get the laptop off site and I am unable to transfer files to the site location. Is there a way to remedy this issue. Why am I getting these errors when I haven’t from other versions of PLCNext. I have replicated the problem on my personal computer by trying to load the 2024 file to the 2025 application.
