2 Channel Digital Input Modules with Diagnostics and Input Process
Data
750-507, -522
The 750-507 and 750-522 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.

750-506
The 750-506 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.
