In this case write response is already indicating with 0xDF that the service cannot be run. The service
cannot be passed on th the E/A module, ensuring that the error code is immediately present. In all eror
cases, the DPV1 error codes on the one hand (see section
Error during DPV1 communication), and on the
other the general DPV1 error codes (EN50170, PROFIBUS guideline 2.082) are of assistance.
In the example, 0x80 means that error refers to DPV1. D2 00 („module has non PCP“- see section
Error
codes during DPV1 communication) indicates that the modle has no PCP. At this point the procedure
should already have been cancelled after the write. However, if you try to read the result on Slot 2, you will
receive D4 00 („wrong service“ – see section
Error codes during DPV1 communication). That is, this
command is currently not expected, there are no read data available on the slot.
In example 6 you will recognize the other, possible error case:
Function code 0xDE (Error Read), respectively function code 0xDF (Error Write) in connection with error
code 0x80. In these cases, errors on at the DPV1 level are implied. Use the table in the section
Error
codes during DPV1 communication as a reference with regard to the individual error codes.
