16.25.3 HMI Memory Map Designations.
Device Name
MB (bits)
MW (words)
Only 512 words are allocated for use. The first 255 words are also used as bit addresses. Word 0 contains bits 0000 through
000F, word 1 contains bits 0010 through 001F etc. Beware of using words that already have some of their bits designated for
use in the lower area. The same applies for long (double) words. Long words use up two words of memory and must be
designated with even numbered addresses.
