Digital Input Modules

Digital input modules supply one bit of data per channel to specify the signal state
for the corresponding channel. These bits are mapped into the Input Process
Image.
Some digital modules have an additional diagnostic bit per channel in the Input
Process Image. The diagnostic bit is used for detecting faults that occur (e.g., wire
breaks and/or short circuits).
When analog input modules are also present in the node, the digital data is always
appended after the analog data in the Input Process Image, grouped into bytes.
