Redundant PROFIBUS DP interface

SIPROTEC PROFIBUS DP - Bus mapping 6MD662/3/4
C53000-L1840-B011-03
1.4.2
Extended Slave_Diag diagnosis data
“Red_State”
diagnosis
Every redundant PROFIBUS DP interface of the SIPROTEC devices provides six
bytes standard diagnosis and additionally eight bytes extended diagnosis data.
The structure of this extended diagnosis data is defined as “Red_State” diagnosis in
the PROFIBUS DP diagnosis Status Model and these data are sent with every
Slave_Diag message to the PROFIBUS DP master.
Figure 1-8 shows the contents of the “Red_State” diagnosis structure. This structure
contains information about the current status of the slave module which is connected
to the PROFIBUS DP master as well as of the partner module in the redundant slave.
Figure 1-8 Data in the Slave_Diag message of the redundant slave of the SIPROTEC devices
•
Octet 7: Headerbyte
Bits 7 and 6 indicate with the value ’00’ that it is a Device Related Diagnosis.
Bits 5 to 0 contain the diagnosis block length including the Headerbyte (8 bytes).
•
Octet 8: Status_Type
Bits 7 indicates with a ’1’ that it is a Status Model Diagnosis.
The value 1F
hex
in the bits 6 to 0 defines a “Red_State” diagnosis.
•
Octet 9 to 11: Slot_Number, Specifier and Function
These three bytes are not used in the implementation of the redundant slave for
SIPROTEC devices and always set to 00
hex
.
•
Octets 12 and 13: Red_State_1 and Red_State_2
Red_State_1 contains status information of the slave interface (PROFIBUS DP
module) which sends the diagnosis data. Red_State_2 contains status information
from the partner module in the SIPROTEC device.
The meaning of the individual bits in this byte are explained in Figure 1-9.
•
Octet 14: Red_State_3
This application-specific byte is not used in the implementation of the redundant
slave for SIPROTEC devices and always set to 00
hex
.
