Message

Unknown bytecode instruction

The VM encountered an undefined bytecode opcode. This is an internal error indicating the bytecode is corrupted or was produced by an incompatible compiler version.

This error should not occur during normal operation. It indicates a bug in the IronPLC compiler or VM, or a version mismatch between the compiler and the VM.

Report this as a bug at https://github.com/ironplc/ironplc/issues with the .iplc file and the source program that produced it.
