bBusy : BOOL;
bErr : BOOL;
bErrornumber : DWORD;
END_VARName | Type | Description |
|---|---|---|
bBusy | BOOL | This output remains TRUE until the function block has executed a command. While Busy = TRUE, no new command will be accepted at the inputs. Note that it is not the execution of the service that is monitored in terms of time, but only its acceptance. |
bErr | BOOL | This output shows the error state. |
bErrornumber | DWORD | Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. |
Command-specific error code (decimal) | Description |
|---|---|
1 | Communication timeout |
2 | ASI slave address not available |
3 - 10 | Reserved |
11 | ASI slave is not activated (slave is not in LAS). |
