The digital output modules have a diagnostic bit for each output channel. When
an output fault condition occurs (i.e., overload, short circuit, or broken wire), a
diagnostic bit is set. The diagnostic data is mapped into the Input Process Image,
while the output control bits are in the Output Process Image.

The digital output module has 2-bits of diagnostic information for each output
channel. The 2-bit diagnostic information can then be decoded to determine the
exact fault condition of the module (i.e., overload, a short circuit, or a broken
wire). The 4-bits of diagnostic data are mapped into the Input Process Image,
while the output control bits are in the Output Process Image.
