Function blocks Description
FB_KL8524 [
}
41]
Function block for the configuration of the KL8524, for reading out the digital signals
and for setting the outputs/LEDs.
4.2.2.1 FB_KL8524
Fig. 25: Function block FB_KL8524
Application
This function block is used to configure the KL8524 [
}
14] , 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).

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 , byKBusOff , byOutMode , byTurnOnDelayCh1 , byTurnOnDelayCh2 ,
byTurnOnDelayCh3 and byTurnOnDelayCh4 are written to the terminals. bBusy goes TRUE. Note that the
inputs/outputs are not updated during this time.
