Profibus DP provides diagnostic information for each slave unit. The Profibus Technology
Option uses the 'ExtDiagData' of the diagnostic telegram (bytes 7, 8 and 9) to provide Trip status
and user specified events. The Profibus master is notified whenever any of the monitored events
change state. The documentation supplied with the master should provide details on how to
access diagnostic information.
An example 605A & B diagnostic response telegram:
Octet 1 Octet 2 Octet 3 Octet 4 Octet 5 Octet 6 Octet 7 Octet 8 Octet 9 Octet 10
00 0C 00 01 16 49 04 01 6A B5
Octet 7 signifies 4 bytes of information is included.
Octet 8 indicates a "Link Overvolts" Trip
Octets 9 and 10 indicate that the EXT DIAGNOSTIC parameter is set to 6AB5.

Octet 8, bits 0 to 4, contain the reason why the drive has tripped. (Bits 5 to 7 are reserved for
future use.) The value contained in bits 0 to 4 have the following meaning:
0 = No Trip
1 = Link Overvolts
2 = Link Undervolts
3 = Link Overcurrent
4 = Heatsink Temperature
5 = External Trip
6 = Input 1 Break
7 = Input 2 Break
8 = Motor Stalled
9 = I*t
10 = Brake Resistor
11 = Brake Switch
12 = Operator Station
13 = Lost Communications
17 = Motor Temperature
18 = Current Limit
20 = 24V Failure
21 = Low Speed Current
Octets 9 and 10 are the most significant byte and least significant byte of the EXT
DIAGNOSTIC input parameter of the TEC OPTION Function Block.

The interface cannot distinguish the reason why the drive has tripped. The value contained in bits
0 to 4 have the following meaning:
0 = No Trip 31 = Tripped
