Input Status Bits

The PROFINET Scanner's 32 bits of input status provide information about the scanner

GFK-2721A
Indicates the health of the module. A value of 0 indicates
the module is powering up or has failed. A value of 1
indicates the module is functioning properly.
Diagnosis data is available. Set to 1 whenever the
FAULT LED is On; otherwise it is set to 0.
1 = port is connected to another device and is operating
correctly.
0 = port is not connected to another device, or the port
has some sort of error preventing communications.
Set to 0
Indicates whether or not the Power Supply is providing
power to the PROFINET Scanner.
Set to 0
Used to acknowledge the slot's Clear Faults REQ
command bit.
When the PROFINET Scanner sees a Clear Faults REQ
bit transition from 0 to 1, it clears the fault conditions for
that slot. Once that process has completed (whether or
not it succeeds), the PROFINET Scanner sets the
corresponding status bit to 1. This signals to the
application program that the attempt to clear the faults
has completed.
When the PROFINET Scanner sees the Clear Faults
REQ transition from 1 to 0, it immediately sets this status
bit to 0 too. This signals to the application program that
the PROFINET Scanner has seen the transition to 0, so it
is possible to signal another Clear Faults request.
Set to 0
