Slave Diagnostics Message
Error decode byte
Bit Name
00 Error decode
~
07
In case the Error decode byte is 128, i.e. PROFIBUS DP-V1, the Error code 1 byte can have the possible val-
ues defined in the table below.
Error code 1 byte
Error class code
0 ~ 9 Reserved
10 Application
11 Access
12 Resource
13~15 User specific
Error code 2 byte
This error code will always contain user specific error codes. If necessary, refer to the slave device's documen-
tation for decoding the returned byte.
The code determines the protocol type of the slave which returned the error
code. Since this error scheme can also be used in network applications contain-
ing protocol converters (i.e. gateways), non-PROFIBUS protocols are also
defined in this list.

Description
Description
Error codes related to the application, i.e. the
slave device it self or I/O modules connected to
this device.
Error codes related to accessing the requested
data area in the slave device or I/O modules
connected to the slave device.
Error codes related to resources inside the
slave device which are required to process the
requested data, e.g. functions required to
implement a requested action.
