4.1 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.
4.1.1 Output Control Bits
The PROFINET Scanner’s 32 bits of control output data can be used to trigger module
actions.
Table 11
Output Bits Name Description
1 Slot1 Clear Faults REQ 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.
