PA: Remote Operation
Diagnostics
All diagnostic information shown below is viewable via PDM.
Diagnosis reply (applies only to cyclic masters)
This is a response to a GET-DIAG message.
During DPV0 data exchange, the PROFIBUS PA slave will notify the Master when a
serious error occurs. The Master will then send a Diagnosis request. The reply to this
request is normally logged in the PLC and is referred to as the "Hex values."
The reply may contain two parts. The first part is 6 bytes long and is defined by the
PROFIBUS standard. If there is a second part, it is called the ’extended diagnostic’ and it
is eight bytes long. The last four bytes of the extended diagnostic message give the error
code shown below. (The same information is also available acyclically via the Diagnosis
Object.
Status Codes for Bad Quality
Values in hex notation Description
0x10
The LOE timer has expired: this could be caused by
LOE or by a sensor malfunction: value is BAD.
0x01
There is an error in the configuration of the function
blocks in PROFIBUS PA
a
.
0X1F
The function block has been placed out of service.
(You will see this only if you read status word via
acyclic services, after placing the function block out of
service.)
0xC4 Bad configuration: value is BAD.
0XDE AI block out of service: value is BAD.
a.
This could happen when a firmware download has been done, but a system
reset has not been done. This could also happen if the function blocks are not
configured properly using PDM or acyclic services.
Status Codes for Uncertain Quality
Values in hex notation Description
0x4B Value is a substituted value (normally used in Failsafe).
0x4C/0x4F Initial value.
0x47 Last usable value.
