2 Channel Digital Input Module with Diagnostics and Output Process
Data
The 750-418 digital input module supplies a diagnostic and acknowledge bit
for each input channel. If a fault condition occurs, the diagnostic bit is set.
After the fault condition is cleared, an acknowledge bit must be set to re-
activate the input. The diagnostic data and input data bit is mapped in the
Input Process Image, while the acknowledge bit is in the Output Process
Image.
