IR n+3
This IR word contains information about the PROFIBUS-DP error
status.
IR n+3 will indicate the error type and the station address of the
station that is in error. If more than one station is in error, it will
report on the first station that is detected to be in error. After
removing the cause of the error it will report on the next station
that was found in error. If the error is in the master itself, the
Station address will show the value FFh.
The following table lists the error types.

Note
When the PROFIBUS hardware does not function properly (P-DP
H/W failure, IR n+2.06 bit is ON), the contents of this word is set
to 0.
IR n+4
Unit Number and Message Length
When IR n+2.13 is set (Reply in output mailbox), this IR word
contains the length of the message that can be retrieved with an
IORD instruction. Combined with the Unit number, this constitutes
the correct source information for the IORD instruction. Refer to
section 6-3 for more details about the IORD instruction.
Note
When the PROFIBUS hardware does not function properly (P-DP
H/W failure, IR n+2.06 bit is ON), the contents of this word is set
to 0.
