2 Channel Digital Input Module with Diagnostics and Output Process
Data
750-418, 753-418
The 750-418, 753-418 digital input module supplies a diagnostic and ac-
knowledge bit for each input channel. If a fault condition occurs, the diagnos-
tic 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.
