Troubleshooting and Diagnosis Options
11.2.1.4 Master address
Standard diagnosis byte 4
The slave enters the station address of the master into this byte, after the master has
sent a valid parameterization telegram. To ensure correct function on the PROFIBUS
it is imperative that, in the case of simultaneous access of several masters, their
configuration and parameterization information exactly matches.
11.2.1.5 Manufacturer's identifier
Standard diagnosis byte 5 + 6
The slave enters the manufacturer's ID number into the bytes. This is unique for each
device type and is reserved and stored by the PNO. The ID number of the measuring
system is 0x0CE3.
11.2.1.6 Length (in bytes) of the extended diagnosis
Standard diagnosis byte 7
If additional diagnosis information is available, the slave enters the number of bytes
(including this one) at this point, which still follows in addition to the standard
diagnosis.
11.2.2 Extended diagnosis
In addition to the DP standard diagnosis report the measuring system provides an
extended diagnosis report which contains the module status:
Status block
Byte 7 Byte 8 Byte 9 Byte 10 Byte 11
Header Status type Slot no. Status-ID Module status
0x09 0x82 0x__ 0x00 0x00 or 0x03

Header:
– Number of bytes in addition to standard diagnosis, including Byte 7
Status type:
– Status block with module status
Slot no.:
– Specification of slot no., which is defective
Status-ID:
– No further differentiation
Module status:
– 0x00 = valid data from this module
– 0x03 = invalid data, missing module
Is reported by the measuring system if a CRC error is present in the
F-Parameters or iParameters
Bytes 12 to 15 are intended for service purposes
