750-506, 753-506
The 750-506, 753-506 digital output module has 2-bits of diagnostic informa-
tion for each output channel. The 2-bit diagnostic information can then be de-
coded 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 Proc-
ess Image.

4 Channel Digital Output Modules with Diagnostics and Input Process
Data
750-532
The 750-532 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.
