Digital Output Modules
The digital output modules provide one bit as the process value per channel that
indicates the status of the respective channel. These bits are mapped into the
output 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). For some I/O modules, the data bits also have
be evaluated with the set diagnostic bit.
If analog output modules are in the node, the digital data is grouped in bytes and
added after the analog output data in the output process image.

15.3.2.2 2-Channel Digital Output Modules with Diagnostics and Input Data
In addition to the 2-bit process values in the output process image, the digital
output modules provide 2 bits of data in the input process image. A diagnostic bit
for each output channel indicates an overload, short circuit or wire breakage.
