What Is A Fail Safe Mode? What Does A Fail Safe Mode Mean?

1.	What Is A Fail Safe Mode? What Does A Fail Safe Mode Mean?
Answer» This mode defines the status of signals in IO modules if a BUS or system failure occurs. It is common that all output signals are going to the zero VOLTAGE level in a FAILSAFE situation. The status is important in FUNCTIONAL safety applications where a profile such as PROFIsafe is USED. This mode defines the status of signals in IO modules if a bus or system failure occurs.
