PROFIBUS DP Communications 35
Publication 2711-6.3
Profibus DP provides a 32 byte diagnostic service (the PanelView
manages and transfers only 20 bytes). Bytes 1 through 6 are defined
by the PROFIBUS DP standard. Bytes 7 through 20 of the diagnostic
data are PROFIBUS DP–Slave specific. The PanelView extended
diagnostics are defined as follows:
Byte Description
7
This is the header byte. Per the DP standard, bits 6 & 7 are 0 which indicates
device related diagnostics. Bits 0 through 5 contain the length of the extended-
diagnostics including this byte. The length is fixed at 14 bytes.
8 & 9 The number of the fault that has occurred (if any).
10
The following bits are set, if the corresponding conditions apply.
Bit 0 – The PanelView was locked by the DP Master, but communications from
the DP Master ceased. This code will be available to the DP Master once com-
munications have been restored.
11
The value of an invalid output block number received by the PanelView in the
multiplex command word.
12
The value of an invalid input block number received by the PanelView in the
multiplex command word.
13
The following bits are set if a type error was detected in the Check–Config re-
quest for one or more of the modules.
Bit 0 – The Type of Module 1 is incorrect.
Bit 1 – The Type of Module 2 is incorrect.
Bit 2 – The Type of Module 3 is incorrect.
Bit 3 – The Type of Module 4 is incorrect.
14
The following bits are set if a consistency error was detected in the Check–Con-
fig request for one or more of the modules.
Bit 0 – The Consistency of Module 1 is incorrect.
Bit 1 – The Consistency of Module 2 is incorrect.
Bit 2 – The Consistency of Module 3 is incorrect.
Bit 3 – The Consistency of Module 4 is incorrect.
15
The following bits are set if a format error was detected in the Check–Config
request for one or more of the modules.
Bit 0 – The Format of Module 1 is incorrect.
Bit 1 – The Format of Module 2 is incorrect.
Bit 2 – The Format of Module 3 is incorrect.
Bit 3 – The Format of Module 4 is incorrect.
16
The following bits are set if a length error was detected in the Check–Config
request for one or more of the modules.
Bit 0 – The Length of Module 1 is incorrect.
Bit 1 – The Length of Module 2 is incorrect.
Bit 2 – The Length of Module 3 is incorrect.
Bit 3 – The Length of Module 4 is incorrect.
17 Module configuration of the Real Time Output module.
18 Module configuration of the Real Time Input module.
19 Module configuration of the Multiplexed Output module.
