Hello,
If I use PLCnext Engineer 2025.9 and AXC F 2152 with firmware 2025.6, can I also use PLCnext Technology Toolchain 2024.6? Or should I be strictly using PLCnext Toolchain 2025.0?
Thank you in advance.
The new 2025 SDK produces binaries that are incompatible with pre-2025 firmwares.
Normally binaries from older SDKs can also run on newer firmwares, but with 2025 that won’t work.
