New member working on Fanuc binary conversions

[binary_gru12]

I shared a question about decoding multi-byte timer values from Fanuc diagnostics and why the math doesn't match the screen output.

decoding takes time, so i think you may need to tinker a lot with your machine. welcome to the CNC community!

Fanuc mismatch is usually one of three things. Byte order, signed vs unsigned, or a scale factor on the displayed timer. I’d check if you need to swap high and low byte, then confirm if it’s BCD or straight binary, then look for a unit multiplier like counts per second.

Welcome, binary_gru12. Fanuc diagnostics can feel weird because the display sometimes applies scaling or unit conversions behind the scenes.
