Data Length	The following table shows the relationship between the actual data length of the
	island and the length of the code on INTERBUS. The actual data length (anywhere
	from 0 to 16 words) represents the greater of the input or output data length.

Actual Length of Island Data		INTERBUS Data Length	Data Length Code (Hex)

2 words		2 words	2

3 words		3 words	3

15 to 16 words		16 words	12

17 to 24 words**		24 words	13

25 to 26 words**		26 words	11

* The status word is included in the data length, so the minimum allowable data length for an Advantys island is 2
words (data word + status word).
** The STB NIB 1010 INTERBUS NIM supports only up to 16 words in each direction (input/output).
