Command / Response Reference
Response Codes
Slot number (Command)
The parameter Slot_Number is used in the destination device for addressing
the desired data slot (typically an I/O module). The number ranges from 0 to
254.
Index number (Command)
The parameter Index is used in the destination device for addressing the
desired data block within a specified slot. The number ranges from 0 to 254.
Data length (Bytes) (Command)
The Data length indicates the number of bytes, which have to be read. If the
actual data block length is less than requested, the length in the response will
be the actual length of the data block. If the actual data block length is greater
or equal than requested, the response will contain the requested length of
data. The number ranges from 0 to 240.
Data (Response)
Requested data block as retrieved from the PROFIBUS DP-V1 slave device.
Error decode (Response)
The Error decode byte defines the type of errors reported in the Error code 1
and Error code 2, e.g. a PROFIBUS DP-V1 error.This response will only be
returned if the FINS message was delivered successfully, but the PROFIBUS
service returned an error. Refer to Appendix B-5 PROFIBUS DP-V1 Error
codes for more information.
Error code 1, Error code 2 (Response)
The contents of the Error code bytes depends on the contents of the Error
decode byte and the slave device. Refer to Appendix B-5 PROFIBUS DP-V1
Error codes for more information.
