Issue:
How to configure ATV212 to have control and ref via terminals but monitoring over serial (LONworks)?

Product Line:
Altivar 212

Environment:
All

Cause:
Programming

Resolution:
If logic input function 48 is not used, then whenever communication is established, it overrides the control. This means that if LON is not operational, commands come from Cmod definition (e,g F input) and frequency from Fmod (e.g. VIB). But as soon as lon works is operational, the drive automatically switches to control via LON. To change this behavior, you have to use function 48. Set forced local to be permanently active by setting F108=48. This will allow command and reference to always come from Cnod/Fnod.
