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.
