Internal data point _RK512

The driver notifies its status to the WinCC OA via an internal data point of type _RK512. This data point can also be used for changing the driver settings during runtime. Each driver with driver number num uses the internal data point _RK512_num. The data point _RK512 has the following structure:

_RK512
	AliveSndDp
	AliveSndTimeout
	AliveRcvDp
	AliveRcvTimeout
	ReadComponent
	ConnState
	ErrorSPS
	ErrorDriver

Table: Meaning of the data point elements.

data point name	Type	Meaning
AliveSndDp	string	Peripheral address for sending Alive messages.
AliveSndTimeout	natural number	Time period in seconds in which Alive messages are sent. A value of 0 disables sending of Alive messages.
AliveRcvDp	string	Peripheral address from which Alive messages are expected. Messages, which can be assigned to this address, are evaluated in no further way by the driver.
AliveRcvTimeout	natural number	Time period in seconds in which the driver waits for messages from the PLC. These can be, but need not be, Alive messages. If no message is received within the specified time, the connection is flagged as broken. A value of 0 disables this procedure.
ReadComponent	string	If a peripheral address is entered here, the corresponding data block is read.
ConnState	boolean	Using this data point the WCCOArk512 driver informs the WinCC OA system whether there is a connection to the PLC . A value of false means it is disconnected, true means connected.
ErrorSPS	natural number	The most recent error code not equal to 0 that was sent by the PLC in an acknowledgement message.
ErrorDriver	natural number	The most recent error code not equal to 0 that was sent by the driver to the PLC in an acknowledgement message.

Note

For data blocks, the value of "ReadComponent" must also contain a value for the data word, i.e. a full peripheral address. The data word is ignored in this case.
