Description of the connected busmodules
read modules 65 ... 128
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 de-
fined below:
Bit position 0
Bit position 1
Bit position 2-7
Bit position 8-14
Bit position 15
Description of the connected I/O modules
read modules 129 ... 192
Length 1-64 words
These 64 registers identify the 3rd block of I/O modules present (modules
129 to 192). Each module is represented in a word. Because item numbers
cannot be read out of digital modules, a code is displayed for them, as de-
fined below:
Bit position 0
Bit position 1
Bit position 2-7
