|---|---|---|
|
i_stRotationMatrix |
SE_MATH.ST_Matrix3D |
A 3D rotation matrix. |
|
i_etOrientationConvention |
ET_OrientationConvention |
Orientation convention used to evaluate the resulting orientation. |
|

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 |
Provides diagnostic and status information. If q_xError = FALSE, then q_etResult provides status information. If q_xError = TRUE, then q_etResult provides diagnostic/error information. The enumeration ET_Result contains the possible values of the POU operation results. |
|
|
q_sResultMsg |
STRING[80] |
Provides additional information about the current status of the POU. |
