Section 3-2
Unit Numbers and I/O Word Allocation
For example, suppose word 28 is set on a Remote Terminal and word multi-
plier 2 is assigned to the Master of that Remote Terminal. The I/O word allo-
cated to the Remote Terminal, viewed from the PC, is computed as follows:
32 words x 2 + 28 words = word 92
A word multiplier is not assigned to a Master to which only Slaves are con-
nected because words will be automatically allocated to the I/O Units on
these Slaves. The I/O words assigned in Remote I/O Systems must not be
the same as the I/O words allocated elsewhere.
The same word multiplier can be assigned to more than one Master as long
as the word settings for the Units connected to the Masters are different, i.e.,
as long as the allocated words differ.
