bErr: The bErr or output goes TRUE as soon as an error occurs. This error is described via the udiErrID
variable.
udiErrID: In the event of an error the output issues an error code (see error codes [
}
59] ). bError goes
TRUE at the same time.

Fig. 28: Function block FB_KL8528Ex
Application
This function block is used to configure the KL8528, to read out the digital signals and to set the outputs/
LEDs.
The function block must be called once per cycle.
The parameters are transferred to the terminal with a positive edge on bExecCfg .
The variable byDisCh switches the standard function of the LEDs off. The LEDs can now be switched
independently of the digital input signal via the PLC with the variables byLEDGn or byLEDYe . Each LED can
be changed individually here.
The respective output can be set to "TRUE" with byKBusOff in the event of a K-bus error (or PLC stopped)
and switch position "auto". Bit 0..7 for the outputs 1..8. If the flag in byKBusOff is not set the output goes
"FALSE" in the event of a K-bus error (or PLC stopped).
VAR_INPUT
bEn : BOOL;
bExecCfg : BOOL;
byDisCh : BYTE;
byKBusOff : BYTE;
byOut : BYTE;
byLEDGn : BYTE;
byLEDYe : BYTE;
bDisManMode : BOOL;
dwOpt : DWORD;
bEn: The function block is enabled by setting bEn to TRUE in the PLC program. With bEn = FALSE the
execution of the function block will be stopped and all outputs reset.
bExecCfg: The configurations byDisCh and byKBusOff are written to the terminals on a positive edge.
bBusy goes TRUE. Note that the inputs/outputs are not updated during this time.
