|
iq_TeSysIslandRef |
FB_TeSys_island |
Reference to the TeSys island device. |
|
i_xExecute |
BOOL |
Upon a rising edge of this input, the function block starts the execution. The outputs q_xDone, q_xError, q_etResult, and q_etResultMsg are reset with the falling edge of i_xExecute. Refer to Behavior of Function Blocks with the Input i_xExecute. |
|
i_xResetMaxVRMS |
BOOL |
If this input is set to TRUE, the value of the parameter q_udiResetMaxVRMS is reset. |
|
i_xResetMaxUnbalanceVltg |
BOOL |
If this input is set to TRUE, the value of the parameter q_udiResetMaxUnbalanceVltg is reset. |
|
i_xResetVltgFlctnStatus |
BOOL |
If this input is set to TRUE, the value of the parameter q_udiResetVltgFlctnStatus is reset. |
|
Output |
Data type |
Description |
|---|---|---|
|
q_xError |
BOOL |
If this output is set to TRUE, an error has been detected. For details, refer to q_etResult and q_etResultMsg. |
|
q_etResult |
ET_Result |
