3.1.4.3.2 Digital Output Modules
Digital output modules use one bit of data per channel to control the output of
the corresponding channel. These bits are mapped into the Output Process
Image.
When analog output modules are also present in the node, the digital image
data is always appended after the analog data in the Output Process Image,
grouped into bytes.

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.
