Hi Raghu,

Have you checked the list file to see if the bits actually end up at the addresses you expect?

My Raisonance assembler lets me do this:

DSEG AT 20H

IOBYTE_1:    DS   1

10HPMOTOR BIT  IOBYTE_1.0
SOL_LOAD  BIT  IOBYTE_1.1
....
....
SOL_REV   BIT  IOBYTE_1.7

Which will correctly overlay the bits for certain. If your ASEM_51 supports this syntax, I would use it if I were you.


Best regards,
Rob.
