FB_KL6831KL6841Config
This function block 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 non-volatile 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() received the process values of the KL6831/KL6841. No SMI commands can be sent while the configuration is in progress.
VAR_INPUT
bConfigurate : BOOL := FALSE;
eCommandKBusWatchdog : E_SMIConfigurationCommands := eSMICommandDoNothing;
eCommandDI1RisingEdge : E_SMIConfigurationCommands := eSMICommandUp;
eCommandDI1FallingEdge : E_SMIConfigurationCommands := eSMICommandStop;
eCommandDI2RisingEdge : E_SMIConfigurationCommands := eSMICommandDown;
eCommandDI2FallingEdge : E_SMIConfigurationCommands := eSMICommandStop;
dwOptions : DWORD := 0;
bConfigurate: Configuration of the Bus Terminal is started by a positive edge at this input.
eCommandKBusWatchdog: Defines the SMI command that is sent as soon as the Bus Terminal is no longer addressed via the K-bus (see E_SMIConfigurationCommands). Corresponds to register 33 to 35 of the Bus Terminal.
eCommandDI1RisingEdge: Defines the SMI command that is sent as soon as a rising edge is detected at input 1 of the Bus Terminal (see E_SMIConfigurationCommands). Corresponds to register 36 to 38 of the Bus Terminal.
eCommandDI1FallingEdge: Defines the SMI command that is sent as soon as a falling edge is detected at input 1 of the Bus Terminal (see E_SMIConfigurationCommands). Corresponds to register 39 to 41 of the Bus Terminal.
eCommandDI2RisingEdge: Defines the SMI command that is sent as soon as a rising edge is detected at input 2 of the Bus Terminal (see E_SMIConfigurationCommands). Corresponds to register 42 to 44 of the Bus Terminal.
eCommandDI2FallingEdge: Defines the SMI command that is sent as soon as a falling edge is detected at input 2 of the Bus Terminal (see E_SMIConfigurationCommands). Corresponds to register 45 to 47 of the Bus Terminal.
dwOptions: Reserved for future extensions.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
udiErrorId : UDINT;
wTerminalDescription : WORD;
wFirmwareVersion : WORD;
sDescription : STRING;
bBusy: When the function 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. Reactivating the function block via the bConfigurate input sets the output to FALSE again.
udiErrorId: Contains the command-specific error code of the most recently executed command. It is reset to 0 by activating the function block again via the input bConfigurate. See Error codes.
wTerminalDescription: Contains the terminal designation (e.g. 6831). Corresponds to register 8 of the Bus Terminal.
wFirmwareVersion: Contains the firmware version. Corresponds to register 9 of the Bus Terminal.
sDescription: Terminal designation and firmware version as string (e.g. 'Terminal KL6831 / Firmware 1D').
