VAR_OUTPUT
bBusy : BOOL;
bStaSwiAuto : BOOL;
wStaPoti : WORD;
wStaOut : WORD;
bErr : BOOL;
udiErrID : UDINT;
bBusy: bBusy is TRUE as long as the configuration is being written (start with bExecCfg ). Note that the
inputs are not updated during this time.
bStaSwiAuto: Status of the switch. TRUE = "auto" FALSE = "man".
wStaPoti: Status of the potentiometer. CCW stop = 0000
hex
= 0
dec
= 0 V, CW stop = 7FFF
hex
= 32767
dec
=
10 V.
wStaOut: Status of the analog output signal. CCW stop = 0000
hex
= 0
dec
= 0 V, CW stop = 7FFF
hex
= 32767
dec
= 10 V.
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.
VAR_IN_OUT
stInData : ST_KL8548InData;
stOutData : ST_KL8548OutData;
stInData: Process image of the inputs (see ST_KL8548InData [
}
58] ).
stOutData: Process image of the outputs (see ST_KL8548OutData [
}
58] ).

Fig. 30: Function block FB_KL8548Ex
Application
This function block is used to configure the KL8548, 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 standard function of the LEDs cannot be deactivated.
