Description of the connected I/O modules
Read modules 0 ... 64
Length 1-65 words
These 65 registers identify the coupler 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 ->
Bit position 15 ->
Examples:
4 Channel Digital Input Module = 0x8401
bit 15 14 13 12 11 10 9
code 1 0 0 0 0
hex 8
2 Channel Digital Output Module = 0x8202
bit 15 14 13 12 11 10 9
code 1 0 0 0 0
