PROFINET Scanner Status and Control Data
The VersaMax PROFINET Scanner provides 32 bits of input status data and receives 32 bits of
output control data. The application program in the IO Controller system can monitor the input
status bits and clear faults using the output control bits. This data is associated with slot 0
submodule 1 in the configuration.
Output Control Bits
The PROFINET Scanner's 32 bits of control output data can be used to trigger module actions.

Used to initiate a clear of all Fault conditions and PROFINET
Diagnosis data on the slot. If the attempt to clear the faults succeeds
(and no other faults are present and no faults recur) the FAULT LED
will be OFF after this completes.
A transition from 0 to 1 initiates the clear. The application program
must ensure this bit remains asserted until the Clear Faults ACK
status bit indicates that the remote node has executed the command.
If this is not done, then the request may not be seen / performed by
the PROFINET Scanner because the PROFINET I/O production
cycle is asynchronous to the IO Controller system's application
program.
A transition from 1 to 0 is required before another clear request can
be sent. The application program must keep this value cleared until
the Clear Faults ACK status bit indicates that the remote node has
seen the 0-value.
This request is the only way to clear fault conditions on the
IC200MDL730. It can also be used to attempt to clear fault
conditions on the other intelligent modules more quickly.
Must be 0
