Digital Input Modules

The digital input modules provide a process value of one bit per channel, which
indicates the status of the respective channel. These bits are mapped into the
input process image.
Some digital input modules have an additional diagnostic bit per channel in the
input process image. The diagnostic bit detects faults (e.g., wire breakage,
overloads and/or short circuits).
If analog input modules are in the node, the digital data is grouped in bytes and
added to the analog input data in the process image. 1 sub-index is assigned for
each 8 bit.
Each input channel occupies on instance in the "Discrete Input Point Object"
(Class 0x65).
