8 Channel Digital Output Modules with Diagnostics and Input Process
Data
750-537
The 750-537 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.

3.1.5.4.3 Analog Input Modules

The hardware of an analog input module has 16 bits of measured analog data
per channel and 8 bits of control/status. However, the Ethernet
coupler/controller does not have access to the 8 control/status bits. Therefore,
the Ethernet coupler/controller can only access the 16 bits of analog data per
channel, which are grouped as words and mapped in Intel format in the Input
Process Image.
When digital input modules are also present in the node, the analog input data
is always mapped into the Input Process Image in front of the digital data.
