6.4 Diagnosis via PROFIBUS−DP
Structure of the slave
diagnosis of the SPC200 The slave diagnosis of the SPC200 reacts in accordance with
standard EN 50170 part 2. The following 12 bytes are reĆ
served for slave diagnosis in the SPC200.
Byte Diagnostic address Meaning
1 Station status 1 Gives an overview of the communication status
and the general status of the SPC200
2 Station status 2
and the general status of the SPC200.
3 Station status 3
4 Master PROFIBUS address PROFIBUS address of the DP master via which the
SPC200 was parametrized and which has both
read and write access.
5 Manufacturer identifier
(for SPC200
00C8 )
Describes the type of the DP slave
(here 00C8 )
6
(for SPC200 = 00C8
H
) (here 00C8
H
)
7 Header
(for the device−related diagnosis) Specifies the length of the device−related
diagnosis incl. header.
1)
8 Device−related diagnosis 1
(bits 4...7 = additional information [8]
bits 0...3 = additional information [7] ) Describes in detail the status of the SPC200 in the
form of an 8−figure hexadecimal fault message.
2)
9 Device−related diagnosis 2
(bits 4...7 = additional information [6]
bits 0...3 = fault number [5] )
10 Device−related diagnosis 3
(bits 4...7 = fault number [4]
bits 3...0 = axis identifier [3] )
11 Device−related diagnosis 4
(bits 4...7 = fault class [2]
bits 3...0 = fault class [1] )
12 Reserved Reserved for later extensions
1) The SPC200 enters fixed value 6 in this byte. 6 bytes of device−related diagnosis incl. header byte
are made available/transmitted.
2) [n] = position of the hexadecimal fault message
