Data
750-418,
753-418
The 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.
