KL6301

This function block deals with the KL6301 EIB Bus Terminal communication. It is used for configuring the KL6301 and for starting the data exchange with the EIB network.

	Restrictions Only one call per instance Call must be made once per PLC cycle Instance must be called in the same PLC task as the send and receive blocks assigned to it Maximum 64 instances per PLC project allowed

Inputs

VAR_INPUT
  bActivate        : BOOL;
  idx              : INT := 1;
  EIB_PHYS_ADDR    : EIB_PHYS_ADDR;
  EIB_GROUP_FILTER : ARRAY [1..8] OF EIB_GROUP_FILTER;
  iMode            : INT;
  tTimeout         : TIME := T#5s;
END_VAR

Name	Type	Description
bActivate	BOOL	Activates the function block that configures the KL6301 and then activates the data exchange. If FALSE, any tasks that are still running will be completed and the data exchange will be terminated. If the outputs bActive and bReady are then FALSE, the function block can be reactivated.
idx	INT	If more than one bus terminal per PLC program is used, each KL6301 must have a unique idx number. Valid values from 1...64.
EIB_PHYS_ADDR	EIB_PHYS_ADDR	Physical EIB address. The default address is 1.2.3. This address must be unique in the EIB network!
EIB_GROUP_FILTER	ARRAY OF EIB_GROUP_FILTER	Group address filter. A maximum of 8 filters are possible.
iMode	INT	0 - For firmware B0 and higher - 4 filters with 64 entries each 1 - For firmware B1 and higher - 8 filters with 32 entries each 2 - For firmware B3 and higher - 8 filters, each with 32 inverted entries. In the case of cross communication within the KNX/EIB network of telegrams that are not connected with the KL6301, care must be taken to ensure that these group addresses are contained in the filter so that the terminal does not send an ACK. 100 - For Firmware B1 and higher - Monitor function, all group address telegrams are received. The telegrams are not acknowledged (no ACK is sent). Sending is disabled in this mode.
tTimeout	TIME	Time allowed for a transmit function block to transmit an EIB telegram before a timeout is signaled.

Inputs/outputs

VAR_IN_OUT
  KL6301_IN  : ARRAY [1..24] OF BYTE;
  KL6301_OUT : ARRAY [1..24] OF BYTE;
END_VAR

Name	Type	Description
KL6301_IN	ARRAY OF BYTE	Is linked with the KL6301 input addresses.
KL6301_OUT	ARRAY OF BYTE	Is linked with the KL6301 output addresses.

Outputs

VAR_OUTPUT
  bActive      : BOOL;
  bReady       : BOOL;
  bError       : BOOL;
  iErrorId     : EIB_Error_Code;
  str_Data_Rec : EIB_REC;
END_VAR

Name	Type	Description
bActive	BOOL	The function block was activated.
bReady	BOOL	The function block is ready for sending and receiving data.
bError	BOOL	This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable.
iErrorId	EIB_ERROR_CODE	iErrorId: The output issues an error code in the event of an error. bError goes TRUE at the same time.
str_Data_Rec	EIB_REC	Connected with the send and receive function blocks.
