5. CONFIGURATION
Output parameters Type Description
DONE BOOL
This variable is true when the block is com-
pletely executed. It is false otherwise.
EXEC BOOL
This variable is true while the block is be-
ing executed. It is false otherwise.
ERROR BOOL
This variable is true when the block con-
cludes the execution with an error. It is
false otherwise. It is connected to the vari-
able DONE, as its status is showed after the
block conclusion.
STATUS SERIAL_STATUS
In case the ERROR variable is true, the
STATUS structure will show the error
found during the block execution. The
possible states, already described in the
SERIAL_STATUS data type, are:
- NO_ERROR
- ILLEGAL_SERIAL_PORT
- ILLEGAL_SERIAL_MODE
- ILLEGAL_BAUDRATE
- ILLEGAL_DATA_BITS
- ILLEGAL_PARITY
- ILLEGAL_STOP_BITS
- ILLEGAL_HANDSHAKE
- ILLEGAL_UART_RX_THRESHOLD
- PORT_BUSY
- HW_ERROR_UART
- HW_ERROR_REMOTE
- DCD_INTERRUPT_NOT_ALLOWED
- CTS_INTERRUPT_NOT_ALLOWED
- DSR_INTERRUPT_NOT_ALLOWED
