Interpretation of process data
Following process data are provided:
The interpretation of the process data depend on the mode (BiSS-C or SSI).
Name | Description for BiSS-C mode |
|---|---|
Status_Warning | Status bit “Warning” is part of the BiSS-C frame and is directly communicated from the slave. The bit is active HIGH. For troubleshooting please refer to slave documentation. |
Status_Error | Status bit “Error” is part of the BiSS-C frame and is directly communicated from the slave. The bit is active HIGH. If the error bit is HIGH, it will be also displayed in the “TxPDO State”. For troubleshooting please refer to slave documentation. |
Status_Ready | In the idle state of BiSS-C communication the slave indicates his ready state with high value. Only if the ready bit is HIGH, data transmission can be started. If the ready bit is LOW, please check chapter error handling. |
Status_Diag | Indicates that a new message is available in the “Diag History”. |
Status_TxPDO State | Validity of the data of the associated TxPDO 0 = valid |
Status_Input cycle counter | 2-bit counter for synchronization, is incremented only if a new value is present. |
Position | BiSS-C position value |
Name | Description for SSI mode |
|---|---|
Status_Warning | Status bit “Warning” is deactivated by default in SSI mode. If status bits are activated (0x80p8:02 “Disable Status Bits” = FALSE), the last 2 bits of the SSI frame are directly mapped as warning and error bit. |
Status_Error | Status bit “Error” is deactivated by default in SSI mode. If status bits are activated (0x80p8:02 “Disable Status Bits” = FALSE), the last 2 bits of the SSI frame are directly mapped as warning and error bit. |
Status_Ready | In the idle state of SSI communication the slave indicates his ready state with HIGH value. Only if the ready bit is high, data transmission can be started. If the ready bit is LOW, please check chapter error handling. |
Status_Diag | Indicates that a new message is available in the “Diag History”. |
Status_TxPDO State | Validity of the data of the associated TxPDO 0 = valid |
Status_Input cycle counter | 2-bit counter for synchronization, is incremented only if a new value is present |
Position | SSI position value |
