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.

END_VAR

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

  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. For some errors (e.g. faulty parameters), bError is set immediately after the positive edge at bConfigurate without bBusy switching to TRUE.
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 bConfigurate input.
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 bConfigurate(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')
