With the input data, actual values are specified, and with the output data
target values.
Please note that the amount of provider data (input data) is variable. The
amount depends on whether the transfer of diagnostic data has been
selected. The modules provide one byte for the slot or channel diagnosis,
known as the
module information byte . The diagnostic data is added to the
standard process input data as additional bytes.
8.1 16DI module
8.1.1 Assembly instance ID 101 (input data with diagnosis)
8.1.2 Assembly instance ID 102 (input data without
diagnosis)
8.1.3 Key:

X1-A...X8-A: Input status, channel A (contact pin 4) of slots X1 to X8

