FB_DMXGetSensorValue

VAR_INPUT

bStart                      : BOOL;
wDestinationManufacturerId  : WORD;
dwDestinationDeviceId       : DWORD;
byPortId                    : BYTE;
bySensorNumber              : BYTE := 0; 
dwOptions                   : DWORD := 0;

bStart: The command is started by a positive edge at this input.

wDestinationManufacturerId: Unique manufacturer ID of the DMX device.

dwDestinationDeviceId: Unique device ID of the DMX device.

byPortId: Channel within the addressed DMX device. Sub-devices are addressed through the Port ID. The root device always has the Port ID 0.

bySensorNumber: Number of the sensor whose values are queried.

dwOptions: Options (currently not used).

VAR_OUTPUT

bBusy               : BOOL;
bError              : BOOL;
udiErrorId          : UDINT;
stDMXSensorValue    : ST_DMXSensorValue;

bBusy: When the block is activated the output is set, and it remains active until execution of the command has been completed.

bError: This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in udiErrorId. Only valid if bBusy is FALSE.

udiErrorId: Contains the command-specific error code of the most recently executed command. Only valid if bBusy is FALSE. See Error codes.

stDMXSensorValue: Structure with information about the current state of the sensor.

VAR_IN_OUT

stCommandBuffer         : ST_DMXCommandBuffer;

stCommandBuffer: A reference to the structure for communication (the buffer) with the FB_EL6851CommunicationEx() block.
