Remark
•
PA912 verifies the disconnection as minor error via PROFIBUS Slave I/Os within 500ms just after
some traffic accident happens (such as cable disconnection).In nV-Tool, User are able to confirm
disconnection as minor error at I/O status in System view.
•
All PROFIBUS Slave I/Os are disconnected via PA912.PA912 registered the error logs as "
PROFIBUS request Timeout". In this case , the below problem ,will be suspected to have been
occured and confirmed the equipment and peripherals.
・
All Slave I/Os are not able to operate normally.
・
The PROFIBUS cable connected to PA912 is not disconnected.
Note
・
The value of I/O bus healthy settings in nV-Tool are not any meaning to PA912.the I/Os which are
indicated in nV-Tool does not mean the PROFIBUS -bus I/Os belongs to PA912.
