Description of the connected I/O modules
Read modules 0 ... 64
Length 1-65 words
These 65 registers identify the controller and the first 64 modules present in a
node. Each module is represented in a word. Because item numbers cannot
be read out of digital modules, a code is displayed for them, as defined
below:
Bit position 0
->
Bit position 1
->
Bit position 2-7
->
Bit position 8-14

Length 1-64 words
These 64 registers identify the 2nd block of I/O modules present (modules
65 to 128). Each module is represented in a word. Because item numbers
cannot be read out of digital modules, a code is displayed for them, as
defined below:
