FB_KL6831KL6841Config

The function block FB_KL6831KL6841Config is used to configure the KL6831/KL6841. The configuration is executed when the PLC program starts, or it can be triggered by a positive edge at the input bConfigurate. The parameters are stored in the respective registers of the KL6831/KL6841 in a fail-safe manner. In addition, some general information, such as the firmware version, is read from the KL6831/KL6841.

Example:

The function block is called in the same task as the function block FB_KL6831KL6841Communication().

The function block FB_KL6831KL6841Config() is linked to the process image of the KL6831/KL6841. Once the configuration is complete, the function block FB_KL6831KL6841Communication() receives the process values of the KL6831/KL6841. No SMI commands can be sent while the configuration is in progress.

Name	Type	Description
bConfigurate	BOOL	Configuration of the bus terminal is started by a positive edge at this input.
eCommandKBusWatchdog	E_SMIConfigurationCommands	Defines the SMI command that is sent as soon as the bus terminal is no longer addressed via the K-bus. Corresponds to register 33 to 35 of the bus terminal.
eCommandDI1RisingEdge	E_SMIConfigurationCommands	Defines the SMI command that is sent as soon as a rising edge is detected at input 1 of the bus terminal. Corresponds to register 36 to 38 of the bus terminal.
eCommandDI1FallingEdge	E_SMIConfigurationCommands	Defines the SMI command that is sent as soon as a falling edge is detected at input 1 of the bus terminal. Corresponds to register 39 to 41 of the bus terminal.
eCommandDI2RisingEdge	E_SMIConfigurationCommands	Defines the SMI command that is sent as soon as a rising edge is detected at input 2 of the bus terminal. Corresponds to register 42 to 44 of the bus terminal.
eCommandDI2FallingEdge	E_SMIConfigurationCommands	Defines the SMI command that is sent as soon as a falling edge is detected at input 2 of the bus terminal. Corresponds to register 45 to 47 of the bus terminal.
dwOptions	DWORD	Reserved for future extensions

  wTerminalDescription : WORD;
  wFirmwareVersion     : WORD;
  sDescription         : STRING;
END_VAR

Name	Type	Description
bBusy	BOOL	This output is set as soon as the function block processes a command and remains active until the command has been processed.
bError	BOOL	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. The output is reset to FALSE by the reactivation of the function block via the input bStart.
udiErrorId	UDINT	Contains the command-specific error code of the most recently executed command. It is reset to 0 by the reactivation of the function block via the input bStart (see error codes).
wTerminalDescription	WORD	Contains the terminal name (e.g. 6831). Corresponds to register 8 of the bus terminal.
wFirmwareVersion	WORD	Contains the firmware version. Corresponds to register 9 of the bus terminal.
sDescription	STRING	Terminal name and firmware version as string (e.g. 'Terminal KL6831 / Firmware 1D')
