DI1 assignment in IO Map saying not assigned for both DI1 low or DI1 high.

Published date: 22 February 2019

Why does the DI1 assignment show 'Not assigned' for both DI1 low or DI1 high in IO Map?

Product Line:
ATV600, ATV900


Customer checked DI1 assignment in I/O Map but didn't see DI1 current assignment 'Forward'.

Check menu 5.5 (Command and Reference), and Control Mode to see if it is set to "I/O profile", DI1 assignment only show "Forward" if the control mode is set to "Not Separate" or "Separate".
