Output Description¶
DONE (done)
Data type: BOOL
Output DONE indicates the processing of the Function Block. If DONE = FALSE, the Function Block is not processed due to EN = FALSE and all outputs are set to 0.
For that reason, the other outputs always have to be considered together with output DONE. All other outputs are only valid, if DONE = TRUE.
DONE is set to TRUE for one cycle. For that reason, the output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERR (error)
Data type: BOOL
Output ERR indicates whether an error occurred during block processing. This output always has to be considered together with output DONE. If DONE = TRUE and ERR = TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERNO (error number)
Data type: WORD
Output ERNO provides an error identifier, if an invalid value was applied to an input or if an error occurred during request processing. ERNO always has to be considered together with the outputs DONE and ERR. The value output at ERNO is only valid, if DONE is TRUE and ERR is TRUE.
The encoding of the error messages output at ERNO is explained in a separate table of Error Messages (see, error messages): Error Messages of the Function Block Libraries
ERNO1 (error number 1)
Data type: WORD, Default value: 0, Range: ³0
Output ERNO1 provides additional error information in case an error occurred during processing. ERNO1 always has to be considered together with the outputs DONE, ERR and ERNO. The value applied at ERNO1 is only valid, if DONE = TRUE, ERR = TRUE and ERNO = 6036 HEX (24630 DEC).
The encoding of the error messages output at ERNO is explained in a separate table “Error Messages” (see, error messages): Error Messages of the Function Block Libraries
Encoding of ERNO1 Parameter error messages
ERNO1 of the DPV1 Function Blocks is encoded as follows. The upper nibble (the higher significant 4 bits) describes the error class, the lower nibble represents the error cause.

ERNO2 (error number 2)
Data type: WORD, Default value: 0, Range: ³0
Output ERNO2 provides an additional DPV1-specific error information, if an error occurred during processing. ERNO2 always has to be considered together with the outputs DONE, ERR and ERNO. The value applied at ERNO2 is only valid, if DONE = TRUE, ERR = TRUE and ERNO = 6036 HEX (24630 DEC). The encoding of ERNO2 is completely manufacturer-specific.
